Setting Focus

I went through the forum looking and havn't managed to find a post regarding my particular circumstances to setting focus with custom dialogs.

I am looking for a way to change the focus of the "Install" to default to "Back" on the buttons at the bottom of the screen. For one of my custom dialogs.

Instructor has wrote a very nice example at this thread,



You need only the SetFocus call with system plugin

That has information on changing information on stuff located in the custom dialog but how do I get focus to a button that belongs to the ui (back button) ?

back button id is 3, so GetDlgItem $0 $HWNDPARENT 3

Just found a thread that is identical to your request,

I currently running with

GetDlgItem $r2 $HWNDPARENT 3
System::Call "user32::SetFocus(i r2)"

When I messagebox the $r2 value it comes out as the right handle according to my spy++ app but I can't seem to get this to actually set focus to cancel.

Is it possible that the installer is setting the Install Button to focus after the fact? thus overriding it?

Hold on a couple of seconds, both we shall learn from kichik

$R2 and $2 are not the same. For the System plug-in r2 is $2 and R2 is $R2.

So then the following should work?

GetDlgItem $2 $HWNDPARENT 3
System::Call "user32::SetFocus(i r2)"

Back is still not getting selected as a focus.. 🙁

Where exactly did you put this code?

Hmm... You probably want to set it as the default button and not have focus on it. For that, there's WM_NEXTDLGCTL. Include WinMessages.nsh and use:

GetDlgItem $2 $HWNDPARENT 3

SendMessage $HWNDPARENT ${WM_NEXTDLGCTL} $2 1

I am loading up a custom dialog using InstallOptions::initdialog so its after loading that, and before InstallOptions::show

Actually that worked perfectly thanks a bunch.
