How do you position a window on the screen?

When I run a application how do I make the window open in the middle of the screen instead of the top left?

Ah, a JFrame, then try this;-
   Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
   Dimension frameSize = frame.getSize();
      if (frameSize.height > screenSize.height) {
         frameSize.height = screenSize.height;
      if (frameSize.width > screenSize.width) {
         frameSize.width = screenSize.width;
frame.setLocation((screenSize.width - frameSize.width)/2,(screenSize.height - frameSize.height)/2);
frame.setVisible(true);

Moving layers leaves the old position lines ghosted on the screen!

Hello guys,
I don't know if this is an easy fix or not but this issue has randomly shown it's ugly head and is very irritating!
When I move layers now from position A to position B, the old lines are still shown on screen in position A. Shown in this picture: http://i.imgur.com/6B1mcZq.jpg
Any help on how to remove this issue would be greatly appreciated!

Hi nskmartinez,
For me it sounds like a hardware malfunction Either these lines are caused by internal monitor or graphic card itself. Easiest way to check this is connecting an external monitor. If the same happens on external monitor its graphic card problem and the mainboard needs replacing.
If you need spare parts you can contact an authorized service provider in your country. The guys are able to order all Toshiba parts. Furthermore they can help you to replace the parts if you are not familiar with notebook disassembling.
Sorry for this more or less standard answer but here its user to user forum only and if its really a hardware malfunction you need professional help to get spare parts and replace them. Furthermore you have already tried the recovery disk that should always and work and if not => Hardware problem.

How do I bypass trust computer if the screen doesn't work

Hi,
I have an iphone 5 that has a damaged screen. The phone was water damaged which has affected the screen. The screen turns on and shows the time as it usually would, but the 'touch' component of the screen has been damaged so I can't unlock the phone. The phone still turns on and works. I can receive calls if I have the headset plugged in and play music. I can also use Siri to make calls. . When plugged in to a computer the phone is registered but I need to trust the computer on the phone which I can't do. Is there any way I can bypass the 'trust computer ' while the phone is plugged into a computer so I can access the hard drive on the phone so I can copy all of the photo's?
Any help would be appreciated.

Get the screen replaced.
Also, it's always a really bad idea not to activate iCloud and Find My iPhone.

How to get absolute screen position for component in borderlayout?

I am trying to get the screen location for a point in a component in a panel. The panel has a borderlayout(). The component is currently in the CENTER position of the layout.

How to get the caret position of component embedded in JTextPane?

Hi great java developers ;-)
I want to get the caret position of component which is embedded in StyledDocument / JTextPane.
How has it to be done?
Thank you very much!!!

The Document doesn't know which textPane it belongs to. (It could even be shared by mulitple textPanes).
You get the caret position of a any text component by using:
textComponent.getCaretPosition();

Why does the screen shift to the last tool position

I have a large diagram, so it involves sliding the screen back and fort to see the whole diagram.
If I wire an item then slide the screen over to select another item, the item is selected, however, the screen shifts automatically back to were the previous tool position was. Then I have to re-slide the screen to see my newly selected item. It does this all the time with a large diagram.
Why does LV do this?

Save the vi, even though the title does not show "*", but save it just after your move your screen and want to maintain that view.

I know how to choose to lock the screen in landscape position, though now in iOS7 it doesn't lock. I've tried restarting from various settings (with it to start up in unlocked position, in locked position, in upright position etc.)

Swipe up from the bottom of the screen to display Control Panel.
Tap the Lock icon.

How do you return the screen to default position?

I'm having problems with the position of the desktop screen, it appears at an angle with the left side higher than the right and the right side lower than the left which is very frustrating.
I have updated the firmware correctly, fitted a new PRAM battery and reset the PRAM and NVRAM but still the screen appears at an angle.
I can obviously re-position the screen in the OS manually but it is hard to get the exact position correct.
I was hoping to return the machine to its factory settings, which I would have thought would have returned the screen to its correct straight position. Would this work? Any ideas? Os is this a fault which can't be corrected?
Is this a common problem with the iMac G3?
Any help or info would be appreciated!

Hey Gazzola and Welcome to Apple Discussions,
I can obviously re-position the screen in the OS manually but it is hard to get the exact position correct.
Right using the monitor adjustments.
I was hoping to return the machine to its factory settings, which I would have thought would have returned the screen to its correct straight position. Would this work?
I doubt it. You could try using open firmware reset. From:
http://www.macintouch.com/panfirmware.html
"Open Firmware reset: Hold down command-option-o-f at boot until a white screen appears, and then type the following at the prompt (press return after each line):
reset-nvram
set-defaults
reset-all
Any ideas?
Yes, most likely it's a bad capacitor in the PAV section of the iMac. This can be repaired but it's a pain. You can run an external monitor via the VGA spigot under the oval grill under in the back. Just pop it off (I use a butter knife) and plug in the external. Actually you should do that just to verify it's an internal monitor problem anyway.

My send button on the iMessage screen will not function. I have tried it in every screen position ie. rotated the screen 90 degrees each time. With no results. Any suggestions?

My send button in iMessage does not function. I have tried it in every position ie rotated the screen 90 degrees each time but still will not send the message. Any ideas or sugestions?

Try this:
First you can try signing out messages and then back in.
Make sure IOS is updated to latest version
Reboot device by pressing both the home button and sleep/wake (power) buttons at the same time for 10-15 seconds until the apple logo appears on the screen, then let go.
If that doesn't work then reset the device by going to settings/general/reset/reset all settings
