I’m working on a GUI with a canvas and a number entry field that shows the position of a TLine on the canvas. Now, I would like for the line to move instantaneously when you change the number entry value by clicking the up/down buttons.
Usually, e.g. for text buttons, you do:
fButton->Connect("Clicked()", "receiver_class", this, "MoveTheLine()");
I tried that and “MoveTheLine()” works as supposed to.
So I tried the same thing for the buttons from the number entry which I get by:
fButtonUp = new TGButton(fNumEntry->GetButtonUp()); fButtonDown = new TGButton(fNumEntry->GetButtonDown());
When you click the buttons, the number in the entry field changes just fine but nothing else is happening.
Any ideas on how to make this work?
