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.

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..]]> Fri, 31 Oct 2008 01:11:56 +0000 http://forum.codejock.com/forum_posts.asp?TID=12420&PID=42521&title=cxtptreectrl-drawing-bug#42521 <![CDATA[CXTPTreeCtrl drawing bug : Hi Oleg I think it&#039;s something...]]> http://forum.codejock.com/forum_posts.asp?TID=12420&PID=42172&title=cxtptreectrl-drawing-bug#42172 Author: adrien

Hi Oleg

I think it's something to do with being inside a Pane, and how sizes are updated.

It doesn't happen in the tree control sample.

even if it were using the wrong font to calculate width, that wouldn't put the width out by a factor of about 20.

The thing thinks it's width is my entire screen width.]]> Mon, 20 Oct 2008 20:42:01 +0000 http://forum.codejock.com/forum_posts.asp?TID=12420&PID=42172&title=cxtptreectrl-drawing-bug#42172 <![CDATA[CXTPTreeCtrl drawing bug : Hi, Guess its CTreeCtrl thing....]]> http://forum.codejock.com/forum_posts.asp?TID=12420&PID=42136&title=cxtptreectrl-drawing-bug#42136 Author: Oleg

Hi,
 
Guess its CTreeCtrl  thing. It calculates width using normal font.

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?]]> Mon, 13 Oct 2008 06:37:52 +0000 http://forum.codejock.com/forum_posts.asp?TID=12420&PID=41943&title=cxtptreectrl-drawing-bug#41943
