InstallOptions supports the new UI enhancements in the new NSIS 2. To support them, InstallOptions now has two new functions, initDialog, and show. The first creates the dialog but doesn't show it. It pushes the HWND of the custom dialog to the stack. To get the HWND of any of the controls use:
+
GetDlgItem (output var) (hwnd of the custom dialog) (12000 + field number - 1)+To finally show the tweaked dialog use the show function. + +Here is a little example: +
+ InstallOptions::initDialog file.ini
+ Pop $0
+ IntCmp $0 0 error
+ ; $0 is now the IO dialog HWND
+ ; use getdlgitem with it and sendmessage
+ GetDlgItem $1 $0 12000 ; 12000 + field number - 1
+ ; $1 is now the HWND of the first field
+ CreateFont $2 "Tahoma" 10 700
+ SendMessage $1 ${WM_SETFONT} $2 0
+ InstallOptions::show
+ Goto done
+ error:
+ MessageBox MB_OK "IO error: $0"
+ done:
