How can I prevent Form closing by Ctrl-F4

Cá chu?i posted over 16 years ago

Hi,

I am using TabbedMDIManager and I don't want to close tab when User press Ctrl-F4. In older version(6.3), that is OK but later version(7.1) is not.

I have tried to find property in order to prevent close tab but I can't found. Could anyone show me how to do? By overrides or set propert?

Thanks

I believe there are two ways to get around this:

1. You can override ProcessDialogKey on your mdi child Form and if Ctrl+F4 is pressed, return True.

2. You can set ControlBox on the mdi child Form to False. This prevents Ctrl+F4 functionality.
