Hi,
when using new GUI with scripting you should follow the rules:
1. At the beginning of your macro define all components you will use
to ensure their visibility in global scope
2. After that define functions for creating widget sets and processing
function
So if you want to use the example do the following:
1. Cut&Paste text between ** Cut Here ** lines into file called
StrDialog.C
2. start ROOT as:
root StrDialog.C or
root StrDialog.C("My String", "My Value") or
root
#include <iostream.h>
.L StrDialog.C
StrDialog("My String", "My Value");
3. The way we use such a dialog window in our macros is:
- paste the text at the beginning of your macro in which you want to
call the dialog
- call the StrDialog(..., ...) function somewhere in the macro
Hope this helps.
Happy ROOTGUIing
Radovan
