Fired event when PrinterSetup dialog gets closed (or page margins changed)

rbuser

Hello,

as the title says, I'm looking for an event, which is being fired, when
PrinterSetup dialog within the designer gets closed (or page margins
changed).

Is there one?

Regards,
Mark

There is no such event. You can create a custom descendant of the dialog and
then register it as a replacement to the built-in dialog. The
PageSetupDialog is defined in ppPgSDlg.pas, the registration appears in the
Initialization/Finalization at the bottom. The dialog is displayed by the
TppDesignDialogController.ShowPageSetupDialog method, defined in
ppDesignDialogController.pas

Thanks for your reply, Nard.

Inbetween I've tried the Designer.Report.PrinterSetup.OnPageDefChange event.
I.e. I'm assigning an event handler at runtime. It *seems* to work for my
purpose (I need to react when page margins are being changed), but not
completely. A kind of "refresh" is missing when I change the margins.
Usually I see the designer space become bigger, if the margins become
smaller, and the other way around - immediately that is.

Once I assign the Designer.Report.PrinterSetup.OnPageDefChange event, I see
the changes only after I change the margins, switch to the preview and back.
Calling "inherited" doesn't help.

Since it works in general, it can't be a completely wrong way, can it?

That approach could cause an issue. Internally the TppReport class uses the
PrinterSetup.OnPageDefChange event. Or to be more precise, TppProducer, the
ancestor to TppReport uses it. In ppProd.pas, check out the constructor,
TppProducer.Create to see where this is assigned.
