Description: |
The attached script demonstrates a grab interaction problem on Windows-XP. It creates a pop-up transient dialog, and uses grab to make it modal, waiting until the user clicks OK before interaction with the rest of the application continues. For demonstration the script is kept very simple. Whilst the pop-up dialog is visible, click right on some empty space in the Windows-XP taskbar and select "Show Desktop". This minimises all open application windows. It is then impossible for the user to restore the minimised Tk application window. The application has to be killed using the task manager. This problem appears to be another unintended consequence of bug fix 1847002 (also see #2896605). Using wish 8.5.6 works as expected, after the "Show Desktop" the user can click on the minimised application window in the task bar in order to restore it. | |||

I regularly use modal dialog boxes (i.e. grabbed windows) in my apps under Win XP. When such a box is opened, and when "Windows Logo + M" is depressed (minize all windows), then the application gets into an irrecoverable state and has to be killed with the task manager... Here is the code to reproduce the issue. Using "transient" is at the core of the problem : toplevel .modalToplevel button .modalToplevel.b -text Button pack .modalToplevel.b # Removing this line solves the issue, as the modal dialog # remains and is discardable... : wm transient .modalToplevel . grab set .modalToplevel Now hit "Windows Logo" + M and you're doomed. cjmcdonald added on 2011-09-26 23:18:01: File Added - 424542: dialog_demo.tcl |
