Manual

Development Production Line - The Short Story [single html html chunks and pdf].

Just a setup manual triggered by a hard drive crash in 2007, which made it painfully obvious how much time it costs to install and get the different components up and running. But it already proved to be helpful when upgrading certain components because of the documented version numbers.

Thanks to the unmentioned posters/bloggers whose comments and installation pointers helped getting everything up and running, but alas keeping track where I found all those 'little snippets' would be a project in itself.

Note: As you can see in the statistics at the bottom of this page the manual upped the html count of the jmodalwindow project a bit. Maybe I should look for a different location to host this. ;-)

FAQ

Question 1

I can't change the STOP-icon! I've tried:

UIManager.put("swingx.busy.cursor", "/home/images/custom-cursor.gif");1)

but then the STOP-icon is only changed to a smaller red square with a white X in it, which is not my icon… How can I fix this?


1) Since enhancement 14 it is possible to use JModalConfiguration.setBusyCursor(java.awt.Cursor) as well.

Answer

The white cross on the red background is generated with Utils.getMissingImage() to indicate that the specified icon/image couldn't be found.

To make the image available on the classpath there are two options:

  1. Place the image busy_cursor.gif in for example a subdirectory …/classes/images and add the following line to your code:

    UIManager.put("swingx.busy.cursor", "images/busy_cursor.gif");

    Note: if the class files are packaged in a jar make sure the images are also packaged in that jar.

  2. The image cursor.gif is available in the directory /usr/images. Create a zip or jar file …/dist/lib/usr.zip containing the image and including the subfolders /usr/images. Then add the following line to your code:

    UIManager.put("swingx.busy.cursor", "usr/images/cursor.gif")

    And suppose the application is packaged in …/dist/swingx_v0104_demo.jar then run the application with the following command:

    java -classpath "swingx_v0104_demo.jar;lib/usr.zip" nl.jj.swingx.gui.modal.test.TestModalFrame

Note: In UIManager.put("swingx.busy.cursor", "/home/images/custom-cursor"); remove the first slash, because there is a difference between

  •      getInstance().getClass().getClassLoader().getResource(…); which I used and
  •      getInstance().getClass().getResource(…);

in the way they retrieve the resource.

By the way: Due to a Win32 problem the cursor to must be 32 x 32. To create a 16 x 16 icon use for example the upper left 16 x 16 pixels and fill the rest with a transparent color.

Question 2

I'm having a problem using the waitForClose() method. Basically, when I use this method, the entire application freezes and won't respond to events or repaint itself.

Answer

This is due to the fact that wait() shouldn't be called on the event dispatch thread (see How to Use Threads). Which means the waitForClose() is useless in ActionListeners and the like. For this reason waitForClose() now throws the following Error("Cannot call wait from the event dispatcher thread")2) when the method is called on the event dispath thread.

If you need to implement some action, when the window is closed, use the windowClosed method of for example the WindowAdapter and supply this to the addWindowListener method of the window, you want to monitor. For an example of its usage see: TestModalFrame method init() jbNormalWindow.addActionListener(…);


2) Since enhancement 19 it is now also possible to simulate wait on the event dispatch thread (EDT). Just call the enableWaitOnEDT() method of the JModalConfiguration class to activate this. Note: Because this method could throw a java.lang.SecurityException if a security manager exists and its SecurityManager.checkAwtEventQueueAccess() method denies access to the EventQueue, it isn't activated by default.
