Editable ComboBox focus problem

Hi,
I have created a ComboBox with editable property set to true.
The problem is ... when the focus is on the ComboBox.... if I click somewhere outside, the focus still remains in the ComboBox.
Only tabbing out or shifting the focus to some other component, removes the focus from ComboBox.
Any help is appreciated.
Thanks in advance !!

That should be true for any Flex component. Focus is always on something, you have to move it to a new place otherwise it gets restored back to what last had foucs.

Set border color of editable ComboBox on focus

What I want to do, is set BorderBrush of editable ComboBox. I'm using slightly modified default WPF templates. They are structured like below:
<ControlTemplate x:Key="ComboBoxEditableTemplate" TargetType="{x:Type ComboBox}">
<Grid x:Name="templateRoot" ...>
<ToggleButton x:Name="toggleButton" ... />
<Border x:Name="border" ...>
<TextBox x:Name="PART_EditableTextBox" ... />

</Border>
</Grid>
</ControlTemplate>
ToggleButton template:
<ControlTemplate TargetType="{x:Type ToggleButton}">
<Border x:Name="templateRoot" ...> 
<Border x:Name="innerBorder" ...> 
<Border x:Name="splitBorder" ...>
<Path x:Name="arrow" ... />
</Border>
</Border>
</Border>
</ControlTemplate>
And now, what should happen.
When PART_EditableTextBox.IsFocused is equal to true then set
templateRoot.BorderBrush and innerBorder.BorderBrush to another color (for example red and blue).
It would be very simple if there was only one BorderBrush to set, because I could use
TemplateBinding to bind this property to ToggleButton element.
For me, the problem are nested templates. I don't know how to refer to inside of another template.
I hope you can help me.
It would be very good if I didn't need to use C# code, just XAML.

>>I don't know how to refer to inside of another template.
You cannot. But since the PART_EditableTextBox is part of the ControlTemplate of the ComboBox you could add the trigger to this control template and then for example set the BorderBrush property and the Background propery of the ToggleButton and bind these
to the BorderBrush properties of the Borders in its ControlTemplate:
<ControlTemplate x:Key="ComboBoxEditableTemplate" TargetType="{x:Type ComboBox}">
<TextBox x:Name="PART_EditableTextBox" ... />
<ToggleButton x:Name="toggleButton" ... />
<ControlTemplate.Triggers>
<Trigger Property="IsFocused" Value="True" SourceName="PART_EditableTextBox">
<Setter Property="BorderBrush" TargetName="toggleButton" Value="Red"/>
<Setter Property="Background" TargetName="toggleButton" Value="Blue" />
</Trigger>
</ControlTemplate.Triggers>
<Style x:Key="ComboBoxToggleButton" TargetType="{x:Type ToggleButton}">
<Setter Property="OverridesDefaultStyle" Value="true"/>
<Setter Property="IsTabStop" Value="false"/>
<Setter Property="Focusable" Value="false"/>
<Setter Property="ClickMode" Value="Press"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ToggleButton}">
<Border x:Name="templateRoot" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="2">
<Border x:Name="innerBorder" BorderBrush="{TemplateBinding Background}" BorderThickness="2">
<Border x:Name="splitBorder">
<Path x:Name="Arrow" Data="{StaticResource DownArrowGeometry}"
Fill="Black" HorizontalAlignment="Center" Margin="0,1,0,0" VerticalAlignment="Center"/>
</Border>
</Border>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
If you don't want to use the Background property for this, the other option is to create your own custom class that derives from the ToggleButton class and add a dependency property called "InnerBackground" or something to this class and replace
the ToggleButton with your custom ToggleButton and replace the binding to the Background property with a binding to the new dependency property and set this one in the control template for the ComboBox.
Hope that helps.

Losing focus on editable combobox

Hi everyone!
I have created a combobox and setEditable is set to true but it does not react to the focus lost method.But when the setEditable is set to false then the focus lost method is executed. According to the following Sun Developer sites(http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6433257,
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4628933) this is some kind of bug.
Is there no way that I can have an editable combobox that reacts to the focus lost method I mean that loses focus?

When you have an editable combo box the editor has focus, not the combox box. So I guess you would need to add the FocusListener to the editor itself and not the combo box directly.

Calling1.4.1 signed applet from Javascript causes keyboard/focus problems

Pretty sure there's a JRE bug here, but I'm posting to forums before I open one in case I'm missing something obvious :-)
This issue may be specific to IE, I haven't tested elsewhere yet. Our web application is centered around a signed applet that is initialized with XML data via Javascript. We first noticed the problem when our users started upgrading from the 1.3.x plug-in to the 1.4.x plug-in. The major symptom was that shortcut keys stopped working. I debugged the problem off and on for about a month before I boiled it down to a very simple program that demonstrates the issue (included below). Basically, the program has a function that adds a JButton to a JPanel and registers a keyboard listener (using the new DefaultKeyboardFocusManager class) that prints a message to the console. This function is called by the applet's init() method, as well as by a public method that can be called from Javascript (called callMeFromJavascript()). I also included a very simple HTML file that provides a button that calls the callMeFromJavascript() method. You can test this out yourself: To recreate, compile the class below, JAR it up, sign the JAR, and put in the same dir with the HTML file. Load the HTML file in IE 5.0 or greater, and bring the console up in a window right next to it. Now click the button that says init--you should see the small box appear inside the button that indicates it has the focus. Now press some keys on your keyboard. You should see "KEY PRESSED!!!" appearing in the console. This is proper behavior. Now click the Init Applet from Javascript button. It has removed the button called init, and added one called "javascript". Press this button. Notice there is no focus occurring. Now press your keyboard. No keyboard events are registered.
Where is gets interesting is that if you go back and make this an unsigned applet, and try it again, everything works fine. This bug only occurs if the applet is signed.
Furthermore, if you try it in 1.3, signed or unsigned, it also works. So this is almost certainly a 1.4 bug.
Anyone disagree? Better yet, anyone have a workaround? I've tried everything I could think of, including launching a thread from the init() method that sets up the components, and then just waits for the data to be set by Javascript. But it seems that ANY communication between the method called by Javascript and the code originating in init() corrupts something and we don't get keyboard events. This bug is killing my users who are very reliant on their shortcut keys for productivity, and we have a somewhat unique user interface that relies on Javascript for initialization. Any help or suggestions are appreciated.

I tried adding the requestFocus() line you suggested... Same behavior.
A good thought, but as I mention in my description, the applet has no trouble gaining the focus initially (when init() is called). From what I have seen, it is only when the call stack has been touched by Javascript that I see problems. This is strange though: Your post gave me the idea of popping the whole panel into a JFrame... I tried it, and the keyboard/focus problem went away! It seems to happen only when the component hierarchy is descended from the JApplet's content pane. So that adds yet another variable: JRE 1.4 + Signed + Javascript + components descended from JApplet content pane.
And yes, signed or unsigned DOES seem to make a difference. Don't ask me to explain why, but I have run this little applet through quite a few single variable tests (change one variable and see what happens). The same JAR that can't receive keyboard events when signed, works just fine unsigned. Trust me, I'm just as baffled as you are.

Focus problem since jre 1.4.2_11

Hi,
I have a awkward focus problem with my java applet. Everything is working fine for jre 1.4.2_10 and all older jre.
The applet is embedded in a large DHTML application running in a shell which uses the internet explorer for rendering. The applet communicates with the sorrounding java script via LiveConnect (JSObjects). We do use the static versioning, in order to determine the adaequate vm version. The controls are all based upon the swing controls, some are a bit modified.
Since the introduction of jre 1.5 update 6 the static versioning does no longer work properly. So, when I run my applet with 1.4.2_11 and all the predecessors a strange focus problem occurs.
When I click outside the applet (focus lost) and the click on a jscript control to get back the focus to the applet, the keyboard input does not reach the applet. The comboboxes do not work anymore. A mouse click is recognized, but the data-list which should appear is only flickering for a moment.
The only way to get the focus back, is to make a mouseclick on a selfmade datepicker (based on swing, implemeted like a popup-window). For sure, the large DHTML application is guilty, but definitely diffrent VM versions do behave differntly.
Does anyone has an idea, has seen similar effects or knows what has been changed in the jre between 1.4.2_10 and 1.4.2_11 ??
Any hint is appeciated! I am lost :-(((
cheers thorsten

Two things: Is there a document detailing manual removal of this JRE (and indeed others); you mention different 'builds' of the same JRE, this is the first time I have read that there are sub-versions/releases of a JRE. Where do I find out the available builds of this JRE and others and how they differ?

2 editable combobox questions

1. addKeyListener(..) not working onto editable combobox.
2. how to scroll the editable combobox when user types into it?
(in case of solving 1st problem, this one is solved too). Maybe there are special methods??
Thank you very much.
Boris.

1) you need to add the listener to the editor of the combobox, no the combobox itself.
2) scroll? I thought it already does an auto select if there is a value in the list which starts with what's typed.

Changing the font of a non-editable ComboBox

Hello everyone,
I need a small combobox. So I set a font of a specific size to the combo's
editor. That works nice als long as the combo is editable; but when it becomes
uneditable, the default bold font is used and some items don't fit in the
field any more. How to prevent this?
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

class ComboEditorFont extends JFrame {
Font fontM= new Font("Monospaced", Font.PLAIN, 13);
public ComboEditorFont() {
    setDefaultCloseOperation(EXIT_ON_CLOSE);
    setSize(100,100);
    setLayout(null);
// Changing the font in the UIManager doesn't work either
/*    Font defaultComboBoxFont= UIManager.getFont("ComboBox.font");
    FontUIResource fui= new FontUIResource(fontM);
    UIManager.put("ComboBox.font", fontM);
//    UIManager.put("ComboBox.font", fui);
    JComboBox cmb = new JComboBox(new String[]{"ABC","DEF","GHI","LMO"});
    cmb.setBounds(20,20, 48,20);
//    cmb.setEditable(true);
    JTextField editor= (JTextField)(cmb.getEditor().getEditorComponent());
    editor.setFont(fontM);
//    cmb.setRenderer(new MyCellRenderer());
    add(cmb);
//    UIManager.put("ComboBox.font", defaultComboBoxFont);
    setVisible(true);

                                                   boolean isSelected,
                                                   boolean cellHasFocus) {
      setFont(fontM);
      setText(value.toString());
      Color background;
      Color foreground;
      JList.DropLocation dropLocation = list.getDropLocation();
      if (dropLocation!=null && !dropLocation.isInsert() &&
       dropLocation.getIndex() == index) {
     background = Color.BLUE;
     foreground = Color.WHITE;
      } else if (isSelected) {
     background = list.getSelectionBackground();
     foreground = list.getSelectionForeground();
      } else {
     background = list.getBackground();
     foreground = list.getForeground();
      setBackground(background);
      setForeground(foreground);
      return this;

Weird focus problems (& 1 workaround)

I am building a wizard with an extension of JDialog. Based on earlier input, I create the JDialog with a bunch of JPanels each with a combobox and a textfield. I have a next, cancel, and back button at the bottom on its own panel. I also have a "Finish" button when I reach the last panel. So I have to change the buttonPanel by putting the finish button on at the end and I put the next button back on when coming back from the last panel.
The problems I have been running into involve getting focus to one of the JTextfields mentioned above. I had a problem when I built my JDialog after clicking the next button. I removed everything from my ContentPane (cp) using cp.removeAll(). After building my JDialog, my code trys to give focus to the first text field. It wouldn't. I tested the text field and it is indeed focusable, visible, and displayable.
The fix was removing each individual component from the content pane instead of doing the removeAll(). Then, after adding everything to the content pane, my textfield could grab the focus.
The only problem that remains is with the back button. When I move back from the final panel the following code is executed:
buttonPanel.removeAll();
//buttonPanel.remove(backButton);
//buttonPanel.remove(finalButton);
//buttonPanel.remove(cancelButton);
buttonPanel.add(backButton);
buttonPanel.add(nextButton);
buttonPanel.add(cancelButton);
Then, as in other cases, the buttonPanel object is added to the content pane. This causes the textfield to be unable to grab focus. I commented out the code and the focus worked fine (but of course my buttonPanel was not correct).
This is happening with 1.4.1 on windows 2000. I don't have another computer to test this one.
Am I doing something inherently wrong or is this a bug?
I've looked around and there are a lot of problems reported with focus and swing, but I wasn't sure if this was a symptom of those problems or if this is something different.
I appreciate any help you can give.
thanks,
Geoff

I won't throw everything at you but this should be plenty. If anyone needs any explanations I am not going anywhere. I'm trying to figure out if the problem is a bug or not.
The workaround is mentioned in a comment for the action listener of nextButton. The problem piece of code that is mentioned at the top of this thread is also commented and it is part of the action listener for backButton.
There are some declarations I have left out and I've left out some helper functions and some private classes, but I looked at it closely. There shouldn't be anything that is a mystery here. But, again, if anything is unclear just give a shout.
thanks in advance,
Geoff

Warranty is valid only in country of original purchase. You have to return
the iPhone to the US for evaluation. Either you return it personally or send
it to a friend/relative/co-worker in the US to take into Apple. Apple will not
accept international shipments for evaluation nor will Apple ship out of the
country after repair/replacement.
Have you tried the standard trouble shooting steps: restart, restore, restore
as new iPhone?

How to exit edit mode (editable comboBox)?

I have an editable comboBox. When a user clicks on the text
area, he can rename the text and the idea is to click outside the
comboBox to commit the new value.
The problem now is when the user clicks outside the comboBox,
the comboBox remains in edit mode(with the blinking prompt). How do
I make it get out of that mode?
thanks in advance

Hi,
setting comBox.editable=false in the function where you
commit the vaules will solve this purpose.
Also remember to set it in edit mode when click event on the
combobox happens
Ex.
<mx:ComboBox id="comBox" click="setMode()"/>
public function setMode():void{
comBox.editable=true;
I hope I have given you a direction to think upon.
Take care

Focus Problem on Solaris with jdk 1.3.1

Hi all,
We are having a focus problem on Solaris. The same code works fine on Windows without any problem.
I am sending the test code and run steps below which you can compile and repeat the problem.
NOTE: When we put a comment on the line "f1.requestFocus();" in TestFocus.java it works OK.
Run Steps :
1. Run TestFocus.class
2. A JFrame appears with 2 text field and a button
3. Try to write something on the text fields. It works OK.
4. Click the button to open a new JFrame
5. A new JFrame opens with a single text field and a button.
6. Click the button to close the second frame
7. You are now on the main JFrame
8. Try to write something on the text fields. It works OK.
9. Repeat the steps 4-7
10. Try to write something on the text fields. You are able to focus and write on the first field. BUT you cannot select or write the second Field!

Significant Computer Window Focus Problem With Verizon Access Manager 7.7.1.0 (2707e)

With the newly released Verizon Access Manager 7.7.1.0 (2707e) there is a significant computer focus problem with it.
What I mean by this is that if I am using ANY application on my computer with the Verizon Access Manager minimized to the Windows System Tray, something will go on with the Verizon Access Manager and it steals the window focus - I am unable to work in the other application unless I click on the application to use it again.
An example of this would be my typing to post a message in this forum. Something occurs in the Verizon Access Manager and my typing is rendered useless unless I click with my mouse on the browser window to be able to use it again.
I'm highly suspecting whenever networks are coming and going in the Access Manager is when the problem occurs.
This problem did not exist in the previous version of the Access Manager I was using.
This is extremely annoying - please issue a fix for this ASAP!

I have found by not minimzing the Verizon Access Manager 7.7.1.0 (2707e) the focus problem does not occur - it appears to be a problem when the app is minimzed to the system tray.

Editable Combobox in a JTable

Hi All,
I have a editable combobox in a normal JTable as one of columns.Can any body help me to set the size to the entered text in editable combobox. Means if I set the length to 5 then it should accpet only 5 characters.so how to achive it ??
Regards

First get cell editor that should be a combobox. Then get its editor that should be text box and then set its size.

Focus Problem on the t3i

My t3i is having focusing problems. What can be the cause? Can I fine to the focus like on the fullframe cameras?
Solved!

OK I will but I just relized maybe it's because I am zooming after focusing and recomposing?
Yep - most lenses are "varifocal" -- meaning that if you carefully focus on a subject at some specific focal length in the zoom range... then zoom to a new focal length, then your subject will no longer be accurately focus. You must re-focus the lens.
There are a few lenses which are "parfocal" -- mean that if you zoom the focal length after focusing, your subject will still be accurately focused. However... VERY FEW lenses are technically "parfocal" (though some are close).
The lenses that I'm aware of which are "parfocal" are:
EF 16-135mm f/2.8L USM
EF 17-40mm f/4L USM
EF 70-200mm f/2.8L USM (only the non-IS version)
That's it. If you use any other lens, you have to re-focus the lens after zooming.
But I also notice you were shooting at 1/15th sec. That's a bit slow but you were at 18mm (which helps.) Here's the guideline on that.
In the 35mm days, there used to be a general guideline that if the shutter speed is equal to or faster than 1/focal-length (e.g. if shooting at 50mm the you'd want to be at least 1/50th sec.... at 70mm you'd want to be at least 1/70th or faster, etc.) would be adequate. This number doesn't apply to your T3i, but I'll get to that in a moment.
But there are a few caveats with that...
First, It assumes you are actually using very good camera-holding technique and you are actually TRYING to be steady. Good camera-holding technique means you are supporting the camera from below -- typically your left is palm-up supporting the bottom of the camera and lens and your elbow is in toward your chest/stomach. Your body weight is centered between your legs and you have a wide stance. This means you are not leaning so your muscles don't have to work hard to keep you upright and your arms work like a brace to support the camera to your body and of course your body is nicely balanced and stable.
Second, It's just a "guideline" -- not a rule. Some people are noticeably able to be more steady than others (and if caffiene makes you jittery and you just drank a coffee... and all that sort of thing.) And sometimes it takes a bit of practice to learn good technique.
Third, It's also not the same for APS-C size sensor cameras (like your T3i). For that camera, you'd have to multiple the minimum speed by the crop factor of the camera. For a Canon APS-C camera it's 1.6 (but if you wanted to use 1.5 that'd be pretty close.) That means at 50mm instead of using 1/50th you'd actually have to use 1/75th (technically 1/80th if we use the 1.6 factor). e.g. 50 x 1.6 = 80 so for 50mm we'd use 1/80th.
If you have a lens that includes image stabilization, then you may be able to shoot a bit slower.
Most image stabilization claims to improve lens stability by 2 to 4 "stops". What that means it that you can reduce the speed of the shutter... two to four times slower than you'd normally need because the lens is stabilizing for you. But more caveats apply because it's not as simple as "you get 4 stops". The stabilization isn't a guarantee... it's just a liklihood. If it has to be less ambitious to stabilize your shot it will be far more likely to succeed. If it has to be more ambitious to stabilize your shot then it'll do it's best... but there's no guarantee that it will work.
You were shooting at 18mm. So if you are using excellent posture and camera-holding technique but don't have image stabilization and you're the "average" person trying to hold the camera steady, then we multiply 18 x 1.6 and get 28.8. There is no 1/28.8th shuter speed so we'll round that to 1/30th (because there is a 1/30th.
1 stop slower than 1/30th is 1/15th.. and the image stabilization probably is adequate to get you 1 stop slower successfully.
2 stops slower is 1/8th. Image stabilization that claims "4 stops" will usually do well at 2 stops. So this is less of a sure-fire thing, but it does tilt the odds in your favor.
3 stops slower is 1/4 sec. At this point you're pushing the image stabilization system... you'll notice that if you shoot a lot of frames, that the "keeper" rate (good shots you like) will be lower, but you'll see that you are getting some.
4 stops slower is 1/2 sec (based on the base of 1/30th for an 18mm focal length on an APS-C size sensor camera). If you push any image stabilized lens to 4 stops, do not expect to get a very high keeper rate. It'll sometimes help you, but you have to accept that you're really being ambitious in your expectations.
That's image stabilization by the numbers... take the focal length, multiply it by your crop factor (which is always 1.6 but if you want to use 1.5 because it's a bit easier to do that math in our head it's close enough), round up to the nearest shutter speed available. If you have image stabilization you can speed up the shutter speed by 1, 2, 3, or 4 times faster... but each time you get more ambitious your odds of getting "keepers" go down (but it's still better than no image stabilization at all.)
The summary is that your minimum shutter speed (assuming good holding technique and that you are steady, etc. etc.) with image stabilization OFF the 1/30th would be your minimum speed. At 1/15h sec you were relying on 1 stop of image stabilization help. The image stabilization technology in the lens is good enought that "most of the time" it probably will be able to do this (not guaranteed... just likely.) If you were NOT using good posture and holding technique... you may be challenging your image stabilization system to try to keep up.

Focus problems

for some reason my canon is having focus problems even on auto focus..what is going on??

Yes, a lot of your problem focusing could simply be that you are trying to use the camera in too low light, if shooting indoors. It will vary depending upon the camera and the lens being used on the camera. There are some ways to get focus to work, such as using an accessory flash (or ST-E2 flash controller) that can emit a Focus Assist (as Tim mentioned in his response above).
But, not knowing your experience with the camera and autofocus cameras in general, I first have to suggest some general info on autofocus and how it works....
This video on YouTube is a good place to start: http://www.youtube.com/watch?v=iAx86nblZ2g. This is the first of three half-hour videos about how the Canon AF system works. Good background info to start with. I'd recommend viewing them all, then you may be able to solve the problem yourself.
