Capturing keyboard shortcuts on my appplication

[Darío Alejandro Guzik]

Hi!

I like to define keyboard shortcuts to do some actions in my application
and I like o know how to do this. The application is an MDI forms
application and the shortcuts should wotk with any form in focus.
Is there a way to do this without adding a KeyDown event on every form?

Thanks

Look at the Win32 API RegisterHotKey() function.

Thanks. Sorry to bother you again but I cannot find the documentation.
Correct me if I wrong:
Ex: I want to capture CTRL-P as a hot key, so in my form, when I create
it I add:

RegisterHotKey(this->Handle, 101, MOD_CONTROL, VK_P);

and I have to add a listener to that message in this form

protected:
void __fastcall FormHotKey(TMessage &Message);
BEGIN_MESSAGE_MAP
MESSAGE_HANDLER(WM_HOTKEY, TMessage, FormHotKey)
END_MESSAGE_MAP(TForm);

and that should be enough?

When I press CTRL-P on any window this method should be triggered?

Never mind... I was usign the wrong virtual code. It works!

Thanks for the advice on the API function

There is an event OnKeyDown in the TForm component.

It's enough to write a function like that.

void __fastcall TForm::FormKeyDown(TObject *Sender, Word &Key,
TShiftState Shift)
{
if (Key == VK_P) ...

}
And dont forget to include

KeyPreview = true;

in the forms constructer
