Forums » Prof-UIS Tech Support » Wrong viewport size in CExtTreeCtrl Collapse All
Subject Author Date

Using a CExtTreeCtrl to display files with icon, I noticed that you can’t scroll horizontally far enough to see the end of an item with a too long name. The issue appears also in the sample tree view (ProfUIS controls).

I’ve tried with no success to change the font size or call SetViewportExtEx. Nothing worked.

How can I fix this ?

This is a known issue. The CExtTreeCtrl control currently uses the scrolling provided by the tree view common control. We would have to recode this common control from scratch to fix this issue. We recommend that you switch to a more powerful CExtTreeGridWnd tree grid control.

This implies quite a lot of modifications to have it behave as before (this is only a file tree view).

Is there a fix planed for a future release ?
