Syntaxtree width

[Kyrremann]

I've started working on my ThingML Editor that I've mention in another post. And I'm trying to do some customizing, but I'm having problem setting the width of the syntaxtree area. Any tips?

What specific problems are you having? What container are you putting the tree in?

I'm working on the DemoRootPane.java and the tree is implemented in a JScrollPane (called treeSP in the code), the problem is that when I start the application, the source tree (of the code) is hidden and I have to use the mouse to drag the window bigger. So I'm trying to set the width by code so that the code tree is visible all the time.

I see. I just updated the DemoRootPane in RSTALanguageSupport to handle this better. Try this:

java code:

final JSplitPane sp = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT,
								treeSP, scrollPane);
SwingUtilities.invokeLater(new Runnable() {
	public void run() {
		sp.setDividerLocation(0.25);
	}
});

You unfortunately have to wrap it in a SwingUtilities.invokeLater() since the parent container must be realized for the JSplitPane to be able to figure out the relative sizes of its children. Alternatively, you can pass an int instead of a float to give an absolute size in pixels rather than a relative size.

Thanks that worked like a charm.

PS: I've also started using github to store my code, so take a look if you'd like.
