How to make a swing app aware of screen size change?

阅读更多关于 How to make a swing app aware of screen size change?

while my swing app is running I change the size of the screen (e.g. from 1024x768 to 800x600). Is there any event I can listen to to be notified about this? Alternatively I could check the screen size in every couple of second, but the Toolkit.getScreenSize() keeps telling me the old value. How could I get the real screen size after the change? Environment: Linux (tested on SuSE ES 11 and Ubuntu 9.04) I appreciate your help. Marton The following worked for me, but I'm on a Mac, so I can't say for sure that it will work on Linux: System.out.println(GraphicsEnvironment

Custom collection crashes DataGrid on Edit

阅读更多关于 Custom collection crashes DataGrid on Edit

Im currently trying to bind the DataGrid.ItemsSource to a custom RowCollection, which implements IList and INotifyCollectionChanged: Public Class RowCollection(of T) Implements IList(Of T) Implements INotifyCollectionChanged Private _List As New List(Of T) ... (Sorry for the VB code, I'll be translating all my code to C# soon.) Notice the class does not derive from any existing CLR collection. I created my own class because I need to override GetItemAt, in order to implement record paging. The Collection Internally adds and removes objects from its own private List _List . Now, I am able to

Extendscript Toolkit debugger fails: Can't start debug session

阅读更多关于 Extendscript Toolkit debugger fails: Can't start debug session

Not a programming problem per se, but rather a programming environment problem that I have been unable to find a solution to. The problem relates to Adobe's Extendscript Toolkit (both 3.5 and 4), but so far I haven't been able to solve the problem, so here I am... The error I get has appeared more or less over night. I didn't experience this problem yesterday, nor this morning. But exactly WHAT has happened is beyond me. I have removed preferences, I have uninstalled, reinstalled, created a new user, restored old preferences from Time Machine and I'm now pretty much lost for options. Basically

I wanted to get scaled instance of a buffered image and I did: public void analyzePosition(BufferedImage img, int x, int y){ img = (BufferedImage) img.getScaledInstance(getWidth(), getHeight(), Image.SCALE_SMOOTH); .... } but I do get an exception: Exception in thread "AWT-EventQueue-0" java.lang.ClassCastException: sun.awt.image.ToolkitImage cannot be cast to java.awt.image.BufferedImage at ImagePanel.analyzePosition(ImagePanel.java:43) I wanted then to cast to ToolkitImage then use the method getBufferedImage I read about in other articles.

问题 I am using silver-light numeric up-down control. Control is set for decimal numbers. Maximum limit 28 and minimum limit is -28 Increment steps are 0.25 using this control in dutch culture so it accept value in the form 1,2 and converts it in to 1.2 3,5 and converts it in to 3.5 10,3 and converts it in to 10.3 27,5 and converts it in to 27.5 Now my issue is that when try to enter value 1.2 it converts it into 12,00 ( I want 1.2 should reflect to 1,2 ) How do I achieve it? or How do I get
