Menu demo

[Josh]

The menu system uses multiple windows, one for each menu or submenu. This also demonstrates dialogs and the requester. The behavior here is fairly complex, one of the most difficult parts of this project.

I think a little more work on the spacing would make it look better, but it looks the same as the Windows version.

When i hover Tools or Help and click for the first time, the text in the menu is not shown.

Then it appears after i move the mouse or something.

The file menu doesn't have the above issue.

 

The File -> Recent Files and Help -> Help contents  texts in gui are cut , onyl half of the last s is shown.
