Make the enter button DO something?? 5

[Jonah86]

This is probably a really dumb question, but: Is there any way to have the enter key execute a button's onclick procedure? So when a user is done typing, they just hit the enter button instead of having to click the button to enter text or whatever it is they're doing.

Probably either really easy, or not possible...I'm hoping I'm just retarded and it's really easy

Thanks!

Have you tried setting the button's "Default" property to True?

You can also use the OnKeyDown event handler of objects on the screen or of the form itself (set KeyPreview to True) to handle the Enter key for specific things on the screen. However, the event handlers only fire for the object that currently has focus.

in the onkeypress..

if key=#13 then
begin
do stuff
end;

#13 is the enter key.

Or you can use the provided constant (its the same as #13 but looks more meaningful.

procedure TForm1.Button1KeyDown(Sender: TObject; var Key: Word;
Shift: TShiftState);
begin
if key = VK_RETURN then
begin
end;
end;

And to actually execute a button's OnClick event, simply call it as you would any other method. If you do nothing with the Sender parameter within your OnClick method then you can pass a nil value, else pass whatever is required.
For example,

  Button1Click(nil);

OR

  Button1Click(Self);

Hope this helps!

Wow, thanks a ton everyone. I imagine at least something up there will work

 

[DelphiAaron]

I personally like to use Button1.Click; better, because it looks like cleaner code

Everyone has a right to my opinion.
