[SOLVED] Openbox + fullscreen wine = focus problems
Hi everyone,
I've got this problem with Openbox: when i play a game via WINE (such as World of Warcraft or Guild Wars 2) in fullscreen, the screen become darker and unresponsive after a few mouse clicks. Then if I alt+tab twice, the wine screen become active again... until i decide to click again.
If I play in non-fullscreen windowed mode, it somehow works (WoW and Hearthstone work but GW2 windows blinks dark for like 1 seconde everytime i click).
If I use only the keyboard, everything's fine.
If I set winecfg to create a virtual desktop, everything's fine too.
If I use any other window managers (i tried with xfce, fluxbox, dwm...) i have no problem so i guess is something with the way Openbox and WINE interract.
Any idea what this could be ?

Do you use a composition manager? Any application specific settings in rc.xml?

LXDE (Openbox) Fullscreen and Layer Problems
Hi,
I run the console "Terminator" as a wallpaper and I sometimes use in fullscreen mode on occasion. I've noticed that once Terminator is in fullscreen, it's "always on top" despite being in the bottom layer. From fullscreen back to normal mode, it's in the bottom again. It's not just with Terminator but all applications are behaving the same way (fullscreen ==> always on top).
I've then binded the "F6 key" to toggle the Raise/Lower window functionality in my ~/.config/openbox/lxde-rc.xml file. That did not do the trick either. Is there a way to make an application to keep their layers even in fullscreen?
Thanks in advance~Do you use a composition manager? Any application specific settings in rc.xml?

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.

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.

FLICKR & PRINTROOM -
I have a swing application of a JFrame with a JMenuBar and JTextfields, JButtons, etc... It works great as a standalone application, or when run as an executable .jar. The problem is when I use JBuilder 7 Native Executable Builder and make a .exe out of the application. It also works fine, but when I click on a JMenuItem that does not bring up a JDialog, just performs a function, it performs the function, but refuses thereafter to give focus to the JTextfields and JTextArea, unless I click on a JButton to bring up a JDialog or JFileChooser, close, then the JTextfields accept focus again (what a workaround!!).
I have added code for a JTextField to requestFocus, grabFocus after the function was performed, and even had the SwingFocusManager disabled, all of which still did not allow focus after the function was performed.
Once again, this is only in the .exe version of my application- the other "normal" ways run fine. Has anyone else had this problem? Has anyone thought up a solution, or is this just a JBuilder unfixable for their cool neat new feature??
Thanks for any ideas,
JimWell, your that did not work either. I think it is not anything to do with the code necessarily- as it is not always reproducible!!- The only commonality is that it occurs only with JBuilders .exe created from the source code- all else works fine. And then, the .exe only has this focus problem on my Dell Inspiron laptop running win 2k- strange- and not always (the first time works-sometimes- and then not afterwards- even when shut down and restarted!!) maybe I'll knock it up to just a OS/Platform problem....well I'll give you the duke anyway for the try-

[SOLVED] HIdden windows stealing focus
Well, I can't be sure is a FOCUS problem, this is the issue:
I'm using compiz, with emerald as window decorator.
Sometimes when emerald crashes (still can't find the trigger, is totally random), or just randomly; minimized windows are like invisible in desktop, if placing the mouse in top of where the window was, it still gets mouse focus, this "invisible" window can't be minimized or closed, the only way to remove it is to restore the hidden window and then minimize again.
Last edited by axelectrik (2015-06-02 23:31:51)Until now, I've had no problems changing that setting and the problem hasn't presented again.
Still, it wasn't something that occured everytime, so in case it happens I'll remove the solved mark.
Thank you a lot -

[SOLVED]Xorg.conf, mouse config problem
The Rapoo M765 mouse can not work properly under normal mouse configuration.
The mouse goes beyond controll when config as below:
hacksign@XSign [14:13:13] : ~
>> cat /etc/X11/xorg.conf.d/50-mouse-acceleration.conf
#Section "InputClass"
# Identifier "Mouse2"
# MatchProduct "RAPOO RAPOO 2.4G Remote Mouse"
# MatchIsPointer "yes"
# MatchDevicePath "/dev/input/event*"
# Driver "mouse"
# Option "Protocol" "auto"
# Option "Emulate3Buttons" "no"
# Option "Buttons" "7"
# Option "ButtonMapping" "1 2 3 6 7"
#EndSection
When there is no any configuration, the mouse can work abnormally. Movement and right/left click work fine, but I can not use scroll wheel,and the "go forward"&"go backward" mouse key can not work too.
(I know Option "ZAxisMapping" "4 5" is the configuration of scroll wheel emulation.)
The real problem is 'mouse beyond controll',the cursor goes crazyly on screen ....
I guess it is something wrong of ButtonMapping option. But when I tried to get button number from command xev,when scroll wheel scrolles, I get something below(the scroll wheel movement is identified as a key event~):

change Driver 'mouse' to Driver 'evdev',solved cursor goes beyond controll problem.
but I still can not use scroll button and 'go forward'&'go backward' button.
(BTW:evdev_drv.so is from local/xf86-input-evdev-trackpoint, and local/xf86-input-evdev-trackpoint package is from AUR)
I think, maybe something wrong with my button number mapping, but I still can not get scroll button number with 'xev' command....

Try to remove xf86-input-mouse and xf86-input-keyboard (same as before, this is deprecated and handled by evdev) and remove also a "joystick" driver if you have it (I have had problem with it conflicting with the evdev driver).

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.

<p>
<input type="button" onClick="document.blah.callMeFromJavascript();" value="Init Applet via Javascript">
</form>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 thorstenTwo 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?

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.

How to solve Oracle SQL Developer connection problem ?
Folks,
Hello. I am using Oracle Database 11gR1. The Database Control Console https://localhost.localdomain:1158/em works correctly. I can create a Database and a table successfully.
My OS is Linux and connects to internet successfully.
In order to run SQL statements. we need to use Oracle SQL Developer. I connect Oracle SQL Developer in the following way:
Connection Name: DB1 (this is my database name as well)
Username: SYS (this is the user name I used to login to the Console)
Password: SYS (this the password used to login to the Console)
Connection Type: Basic
Host Name: localhost
Port: 1158
SID: DB1 (this is created during installing the Database)
But the error message comes up: "Status: Failure - IO exception Connection Reset."

password: enter_your_correct_password given at the time of oracle installation
role: select sysdba if you would connect as sysdba else select normal for users other than sys
hostname: enter your oracle server hostname or ip address eg:- 192.168.11.12
to find the hostname open terminal/command prompt in oracle installed machine
type ---> hostname
type ---->ping hostname
you can find the ipaddress of the server

Reader X - Firefox focus problem
Since I first started using Adobe Reader X, I have had an intermittent keyboard focus problem with Firefox (mostly recently 3.6.14, on Windows 7). If I open a PDF document in a browser tab, sometimes keyboard focus is not returned to Firefox iteself. For instance, I may try to type something into the Firefox search box or URL box, but cannot get keyboard focus there: I cannot get a blinking cursor, though I can select the text there.
I have not been able to duplicate this problem consistently.
The workaround is to go to another application entirely, click to move focus there, and then return to Firefox.I don't know that "focus" is the right term to use, but I have the same exact problem. Do you have a scroll mouse? I've also noticed that when I scroll within an instance of Adobe Reader that's opened in Firefox using the scroll button on my mouse that the scroll bar does not register the change until I move my cursor over it, then the bar will jump to where it's supposed to be. This is really annoying because I can't quickly judge how far along I am in a .pdf.

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,
GeoffI 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
