Question

Using Delphi 2009 on Windows XP to develop desktop application.

Is there any way to make a windows dialog modal to a tab, instead of application. How can I achieve this? Threads? any frameworks supporting this?

Answer 1

One way is to simulate this is:

1. Temporarily disable all child controls of the tab sheet
2. Create a Form
3. Set its Parent to the tab sheet
4. Set FormStyle := fsStayOnTop
5. Set BorderStyle := bsNone

This way you have a dialog on top of a tab sheet and it’s the only thing that users can interact with on this tab sheet, but it doesn’t block the main form ui or other tab sheets.
