CXTPTreeCtrl drawing bug

I've got a CXTPTreeCtrl which I use for a navigation menu.

It's embedded inside a docking pane.

All is good until I set one of the labels to be bold.

As soon as I do that, the list control thinks its width is the whole screen width (or thereabouts), and I get a horizontal scrollbar, with the scroll dragger only about 8px wide.

If I set the label back, it doesn't fix it.

I've actually also seen this with a straight CTreeCtrl inside a docking pane.

I'm not sure therefore if it's a problem with the ctrl, or the docking pane?

Hi,

bump again.

I think this is an issue with being inside a pane.

the width that the client area of the pane (e.g. width of tree ctrl) gets set to is the width of my screen.

I've got 3 monitors, the width of the tree ctrl gets set to 4800px.

This doesn't happen if the tree ctrl is not inside a pane..

I found the problem.

My code was highlighting a path in the tree back to the root node,by setting the item bold and red. My tree was only 2 levels deep, but it was calling into SetItemBold 3 times.

Turns out my recursive code was calling SetItemBold and SetItemColor on the root of the tree ctrl as well (TVI_ROOT). This messes up the width of the control completely.

Taking out that last call fixed the problem. don't know if this problem is a known issue with custom ctl tree control or not, but I couldn't find any evidence to support my earlier theory that it was codejock issue.
