 Topic: CXTPTaskDialog ignoring parentPosted: 09 February 2008 at 4:05pm |

Hi
I've got an app that uses a number of frame windows, each with views in them. One for the main part of the app, and others that are spawned to edit specific content.
Whenever a user closes an edit frame, without saving changes, I post a CXTPTaskDialog-derived dialog to warn them about the changes. I set the parent to be the sub-frame, however it always brings that main frame of the app to the front before displaying the dialog, so the frame the user was working in is immediately covered.
Using spy++ you can see the parent window for the dialog is the desktop, not the window I specified. The dialog centers itself on the parent, but is not a child of the parent.

more on this. this is on XP, so no built-in task dialog.
Inside CXTPTaskDialogFrame::DoModal(), it calls
InitModalIndirect(m_lpDlgTemplate);
this is a CDialog call, it should be passing the parent window pointer in here as well.

looks like there will need to be a m_pParentWnd member added to CXTPTaskDialogFrame to store the pointer from the constructor to be used in DoModal.
Create allows you to pass in a parent, but I need this dialog to be modal.

ignore that last one about adding the member. It derives from CDIalog already.
I worked around it by setting
m_pParentWnd = pParentWnd
in the constructor of my derived class. However, the constructor of the CXTPTaskDialogFrame (and parents) should be modified to allow passing the parent pointer up the constructor chain.
