Before upgrading to current 1879 svn (I was in 1801 svn) this worked, now the splitter sets always about on middle.

#include <CtrlLib/CtrlLib.h>

using namespace Upp;

class TestSplitter : public TopWindow
{
	private:
		// pages column list
		ColumnList pageList;
		
		// page container
		StaticRect pagePane;

		// the splitter
		Splitter splitter;
		
	public:
		TestSplitter();
};

TestSplitter::TestSplitter()
{
	// adds the splitter
	SizePos();
	Add(splitter);
	
	// setup pagelist appearance
	pageList.Columns(1).SizePos();
	
	// adds the columnlist on left
	splitter.Horz().SetPos(100).Set(pageList, pagePane);
}
	
GUI_APP_MAIN
{
	TestSplitter().Run();
}

Hi,

I noticed your trouble with splitter and as I tinkered with it recently I thought I should take a look at it.

Re-order:

splitter.Horz().SetPos(100).Set(pageList, pagePane);


to:

splitter.Horz().Set(pageList, pagePane);
splitter.SetPos(100);


..and your code works. The reason is that in Splitter::Layout, newly added panels cause a re-initialization of splitter position array. I do not think that I did that change... I hope.

I already figured out this with Mirek's help, thanks Smile

Anyways, I guess that some previous (working) code will have to be changed in order to avoid this "bug".

Ciao
