Hello,
I am trying to get familiarized to the gui functions of the ROOT package. Up
to now I have done most of the gui design with Qt and are used to the signal
slot mechanism.
I do not want to mix QT and ROOT code, therefore I hope to being able to use
ROOT for the analysing as well as for the gui.
I have a problem to connect a signal emited by a button to a function which is
declared as a member in the same class.
class Monitor : public TGMainFrame {
private:
// [..] some vars
public:
Monitor(const TGWindow *win, const TGWindow *main, UInt_t w, UInt_t h);
virtual ~Monitor();
// [..]
void DoDraw();
};
the connect call in the constructor:
[..]
button->Connect("Clicked()","Monitor",this,"DoDraw()");
[..]
The code compiles fine but complains during execution about:
"Error in <TQObject::CheckConnectArgs>: slot DoDraw() does not exist"
I have checked the following thread:
http://root.cern.ch/root/roottalk/roottalk02/0735.html
"[ROOT] cant connect slot to THIS pointer ?"
and created a dictionary with
rootcint "mysourceDict" -c "mysource"
and followed the steps explained in:
http://root.cern.ch/root/CintGenerator.html
but it still does not function as it is mentioned.
In fact my DoDraw() function is not even mentioned in the generated files.
I would be glad if sombody might enlighten me because I think the signal slot
mechanism might save lots of my time.
Best regards,
Ralph
