Help with "simple" JFileChooser problem...

Hi all,
how do I set the font in a JFileChooser???
I have tried everything, but it always uses the Look & Feels default font setting. Can I change the default Look&Feels font setting?
Greatfully for any suggestions!
Cheers
Anders ;-D

Hello!
You can use the UIManager, e.g. UIManager.put("FileChooser.font", new Font("Arial",
Font.BOLD, 14);
Well, that didn't seem to help with my case either. So I tried something else: I overrided all of the defaults by using UIManager.put(key, value) this way I got all of the Fonts in the JFileChooser to change.
Correct me if I'm wrong... ;)
- Cathra -
Sample Code that performs the requested:
// Prepare the resources
FontUIResource font12Arial = new FontUIResource( "Arial", Font.PLAIN, 12 );
// Put values into UIDefaults (before initializing the JFileChooser)
UIManager.put( "ToolTip.font", font12Arial );
UIManager.put( "OptionPane.messageFont", font12Arial );
// shown for example
UIManager.put("FileChooser.openButtonText", "OpenUp");
UIManager.put("Button.font", font12Arial);
UIManager.put("Label.font", font12Arial);
UIManager.put("Table.font", font12Arial);
UIManager.put("TextField.font", font12Arial);
UIManager.put("ScrollPane.font", font12Arial);
UIManager.put("ComboBox.font", font12Arial);
UIManager.put("CheckBox.font", font12Arial);
UIManager.put("TitledBorder.font", font12Arial);
UIManager.put("RadioButton.font", font12Arial);
UIManager.put("ToolTip.font", font12Arial);
UIManager.put("TextPane.font", font12Arial);
UIManager.put("TextArea.font", font12Arial);
UIManager.put("Tree.font", font12Arial);
UIManager.put("List.font", font12Arial);
UIManager.put("MenuBar.font", font12Arial);
UIManager.put("Menu.font", font12Arial);
UIManager.put("MenuItem.font", font12Arial);
UIManager.put("TableHeader.font", font12Arial);
UIManager.put("TabbedPane.font", font12Arial);
// somewhere in the code:
JFileChooser c = new JFileChooser();
c.showOpenDialog(aParentFrame);

Small Help Needed in JFileChooser

I've a small problem in using JFileChooser.
I want to disable the doubleclick option if chosen is a file and enable if it is a folder
or
i want both the properties of singleclick and doubleclick to be same.
i.e, if it is a folder as it gets inside the folder. incase of file it shudn't do anything (filechooser shudn't get closed). But as of now the file chooser is getting closed on double click on a file and it returns the selected file's name when i printed using chooser.getSelectedFile(). what i want now is, the filechooser shudn't return anything until i click the open button on the filechooser window.
Can someone help me out in terlling me how to do this
TIA

um.... how about get the JDK?
Also, please don't try to use a non-applet program as if it were an applet. It won't work.
Also, please go through the Sun Java tutorials, especially the first ones about getting started.

Help with custom JFileChooser

Hello everyone,
I would like to customize JFileChooser to display a panel with some text above the folder browse section.
Is this possible... if so, could anyone provide some sample code on how to get this started?

I'm afraid you're on your own. Noone has [ever done something like that before|http://www.google.com/search?q=customizing jfilechooser].

Help needed regarding JFileChooser

hi, this is ravikiran,
I am having a situation where when a save dialog appears, I must provide a default name for the file to be saved in the "File Name" field of save dialog.
Which property of the JFileCooser must be set in order to do this.
help me.
thanx in advance.

The is a method to set the directory and a method to set the file name.
If you need further help then you need to create a [url http://homepage1.nifty.com/algafield/sscce.html]Short, Self Contained, Compilable and Executable, Example Program (SSCCE) that demonstrates the incorrect behaviour, because I can't guess exactly what you are doing based on the information provided.

Submiting forms returns a "Save As File" dialog box

I've got a form that users return via email, one user always gets a Save As File dialog box and since this doesn't match the instructions. User doesn't return the form as others do. Any help greatly appreiciated.

How do I add a JCheckBox to a JTable - URGENT HELP NEEDED

JFileChooser weird problem (Help!!!)

Does anyone here have loading problem with JFileChooser?
I have a class that inherited the JFileChooser class and another class that inherited the JFrame class and this class create an instance of the JFileChooser class.
My program sometime will not show (but sometime will: no changes at all) and they are no exception being shown on the console window what so ever. I can solve my program by initializing the JFileChooser object after showing the application and not before but that stupid JFileChooser is so slow to initialize. What the hell is going on? Any help hint would be appreciated.

I also want to add that the following code is in my JFileChooser class:
protected JDialog createDialog(Component Parent)
JDialog CustomDialog=super.createDialog(Parent);
CustomDialog.setLocationRelativeTo(Parent);
CustomDialog.setResizable(false);
return CustomDialog;
Aside from the abnormally, I don't not what else could be causing the problem!

JCheckBox/Action Listener help

Hey
I'm trying to make an applet with two tabs, a PurchasePanel and a StorePanel, and have data altered in one of them affect the data in the other. On the StorePanel, the data is input infields and through a ButtonListener command it is stored as both a String in a text field on the StorePanel, and as a check box on the PurchasePanel. Now, from the PurchasePanel I need to make an ActionListener function that when the CheckBoxes are pressed, some data is added to another textfield, and when it is unchecked the data is removed. I'm not sure I implemented the actionlistener correctly as the buttonlistener and the actionlistener commands aren't recognizing variables from each other. Any help is appreciated.

If you pass along references to the appropriate panel to the Listeners, then they can update the right thing accordingly eg.
// To enable the StorePanel to add/erase data from a textfield by listening to a checkbox in the PurchasePanel class
// PurchasePanel class
checked.addItemListener(new CheckBoxListener(storePanel));
// CheckBoxListener class
public void itemStateChanged(ItemEvent e) {
    // When checkbox checked
    if(checked)
        storePanel.writeToTextField("blahblah");
    else
        storePanel.writeToTextField("");
}That was pseudocode of course! If you need the PurchasePanel to listen to the button in the StorePanel, you need to do the reverse.

Missing pieces of components (JFileChooser, JButtons, etc) help?

The normal window in the GUI i'm working on, works fine. When i bring up a new NetFrame (e.g. preferences) the components aren't drawn completely. None of the 3 buttons show up, a few check boxes in a tabbed pane show up (not all of them), etc. When i click where a button should be, it appears. When i switch to the other tab in the pane, its contents appear (except for a small missing bottom right corner of the border for a jtextarea), and when i switch back to the first tab, all of its contents appear. When i resize the panel, everything shows up.
I've tried calling validate, revalidate, validateTree, repaint, show, pack, none of them do anything (pack rearranges things, but nothing new appears).
I'm completely out of ideas!
A previous version of the program works fine, so it is something wrong with my code (i.e. not my computer / packages etc).
The thing that really stumps me, is that a JFileChooser appears incomplete -- only showing the file browser section, and the okay button (missing cancel button, and borders etc).
I'm sorry i don't have any sample code to show, there too much to put it all, and i have no idea where the problem is.
I'd appreciate any help or direction you have. THANKS!

Need help for JFileChooser

Hi,
I need help on this one. I have a filechooser class which extended from JFileChooser class. Every thing works fine except this: I want to by hiting the "Enter" key to save the files. The "Enter" key works only when the focus is in the file name text field now, I want it to work when the focus is in the directory area, the file list area and the file type area as well. I try to add the KeyListener but how can I get hold of the component of the three areas of file chooser? I tried to add the KeyListener as Accessory, it didn't work either. Some one please help me.

Try this to let your components react to ActionEvents
comp.addActionListener(new WhatIWantToDo());
// WhatIWantToDo is the inner class.
// Let it do what you want to be the reaction
class WhatIWantToDo implements ActionListener {
public void actionPerformed(ActionEvent event) {
// code on what you want to do
}Or working without an inner class try this
comp.addActionListener(new ActionListener() {
// the event handling
public void actionPerformed(ActionEvent event) {
// your code for behavior
// e.g. System.out.println("There is a reaction");
// or specify a special named component as c1
Object source = event.getSource();
if (source == c1) doSomething();
else if (source == c2) doOtherThings();
});Hope this is of help for what you want. Else let me know.

Customizing JFileChooser (File Size) Need Help

Can you help me with this. I want to customize my JFileChooser. I'm in a Windows environment so the file view that I see is same with that of the option pane of windows. What I would like to do is make the size that is viewed from the screen from ##KB to specific bytes size. (ex. 34421245). Can someone help me on this. I was able to see some codes on the net but those codes are not straightforward. They override the BasicFileChooserUI. Can someone help me on this. I don't want to override the BasicFileChooserUI instead I want to use the JFileChooser and change the size from ###KB to bytes. Thank you. ^_^

Hi Rachel,
My best idea for that is to load the swf files externally, so
that each page is a different swf. A technique like this would be
very simple and quick to use, because it only loads what you need
when you need it.
For example, you'd set the intro page to load right away, and
then when you select "At Work" the intro page unloads and is
replaced by the at work page.
Another thing you may want to consider is holding the images
in an xml file, and then using some basic flash/xml intergration to
load each image as it's called. That way each image isn't stored in
the flash file causing it to increase in size, and instead is
actually loaded externally which is must faster.
There are some great tutorials, if you're intrested, on how
to do both of these at:
http://www.kirupa.com/
Hope I helped some!

Help needed with ItemListeners for JCheckboxes

Hi,
I have created a menu called "Test" and it contains toplevel menu item "File"
and File Menu contains subitems "NEw" and "Exit".
When i click File->NEW it displays a new Frame named f1 which contains 2
Jradiobuttons(r1 and r2 ) and 6 Jcheckboxes(c1,c2,c3,c4,c5,c6).
My Question is how can i write itemlisteners for checkboxes such that after compiling the program when i check anyone of the checkboxes c1,c2,c3 or all c1,c2,c3 then RadioButtob r1 should get enabled.
similarly when i check anyone of the checkboxes c4,c5,c6 or all c4,c5,c6 then RadioButtob r2 should get enabled.
I am sending the code i have written .

JFilechooser .....help please

hi,
while opening file "OPEN" or "SAVE" dialog using JFilechooser, in those dialog, can we have our desired icon instead of Java Application at left most corner in the dialog??
any help please????

setIconImage
public void setIconImage(Image image)Sets the image to be displayed in the minimized icon for this frame. Not all platforms support the concept of minimizing a window.
Parameters:
image - the icon image to be displayed. If this parameter is null then the icon image is set to the default image, which may vary with platform.
See Also:
getIconImage()
That may work...
