Just started messing about with the standard actions in Lazarus and came across a minor problem.

Is in possible to cancel the dialog in the BeforeExecute event, my plan was to ask the user to save the current file (Yes/No/Cancel) before opening another, problem is I don't know how to cancel the Dialog if the User selects Cancel.

My apologies if I'm missing something glaringly obvious but I've never used actions before and although I can work around it I was just hoping I could do it within the actions events themselves.

Cannot you check if the current file needs to be saved and prompt the user for it _before_ opening the dialog?

That's one work around, The FileOpen Action is tied to a couple of controls though (Menu, ToolButton) and I was hoping to do all the work inside (so the menu & toolbutton remain synchronised). It kind of defeats the purpose of the actions if I have to handle this myself.

If it can't be done I'll probably write my own action for opening the file but it seems to me that this is a very common situation so canceling the dialog within the BeforeExecute should be possible returning Cancel as the result.

I think I've just answered my own question, changing the dialogs execute event ???, is this the way to go or is their a simpler solution?

then handle it within the FileOpen Action. I guess there you have if(MyFileDialog.Execute) Then OpenTheFile(MyFileDialog.FileName), right?

So check for the file to be saved as first thing. At least, this is what my common sense tells me.
