Tooltips in a tree ctrl clipped when floating

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   We have some docking panes that have dialogs in them that have the windows tree control in them. When resized so that the pane is too small to handle the text, windows will show a tooltip containing the full text of the item that is clipped.

Everything works fine until the user undocks the docking pane. Once it is floated and resized so some of the text in the tree control is clipped, any tooltip that is displayed by the tree control appears to display "under" the floating pane so that only the area of the tip that extends past the right size of the floating pane is visible to the user.

It seems that the floating pane is higher in the z-order than the tooltip.

This does not happen on a 64 bit Vista OS but does happen on a 32 bit XP OS.

Any suggestions on how to resolve this issue?

	I have noticed a similar problem. I have implemented a tooltip control for some dockable views. If the pane is floating, then the tooltip is displayed underneath the window. I am on XP. Were you able to solve this issue? Thx.

	so oleg got back to me with regards to this issue. it is a known issue of the CToolTipCtrl and floating windows. basically, you capture the TTN_SHOW and SetWindowPos to HWND_TOP for the tooltip to ensure proper z order.

	No I have not. I gave up and moved on due to other priorities. So my issue is still open (customer complaint). Oddly enough we have some panes where this doesn't occur so it drove me nuts trying to figure out just what the difference is.

	Not sure if this helps, but make sure your child window's owner is set to the parent window. m_pane.Attach(&m_wndTree); m_wndTree.SetOwner(this);
