TreeCtrl display bug [message #48108]

U++ has this nice feature when some item can't be displayed in a rect, a tool-tip appears with the full text.

This works fine with a narrow TreeCtrl where you add a very wide child. Mouse-over the child and it will popup perfectly.

But if I add a display to the TreeCtrl, the popup jumps up about 2-3 pixels vertically.

This is an incredibly serious mega bug Laughing

treetest::treetest()
{
	CtrlLayout(*this, "Window title");
	
	tree.SetRoot(Image(), "test");
	tree.SetDisplay(Single<ItemDisplay>());
	tree.Add(0, Image(), "aaaaaaaaaaaaaaaa");
	tree.Open(0);
}

Comment out the tree.SetDisplay(Single<ItemDisplay>()); and the tool-tip vertical jump is no more.

Test case attached.

Hello,

Please create redmine ticket for that issue with the url to forum thread. It is more easier to track them there. And, of course there is less change that the bug will be missed.

Sincerely,
