Gtkmm - signal_button_press_event() not sending signal?
First of all, let me hint that I am very new to Gtkmm programming, and
relatively new to C++ programming in general. I am trying to write a simple program that draws a bezier curve in a DrawingArea which can be manipulated by clicking and dragging its control points. Right now the program draws a curve, but I have not yet successfully implemented anything to manipulate it. That's what I'm working on. I figured I'd start by figuring out how to detect a button click on the DrawingArea. I know I'll need to get the coordinates of the mouse pointer as well. From reading the tutorial, etc. it seemed that Widget::signal_button_press_event() is the appropriate method to use. I have connected it to a signal handler in my MainWindow class. Everything compiles fine but the code in my signal handler doesn't seem to execute. Here's what code it seems you'd need. In MainWindow's constructor (curveArea is my DrawingArea): Code:
curveArea.signal_button_press_event().connect(sigc::mem_fun(*this, Code:
bool MainWindow::on_curve_button_press_event(GdkEventButton* event) able to find something on a mailing list from 2002 that said it was a bug. Seems like that wouldn't be relevant anymore. Any help would be greatly appreciated. If you want all my source code, let me know. Lastly, my development environment: Fedora Core 3 gcc 3.4.2 gtk 2.4.14 glib 2.4.8 libsigc++ 2.0.6 glibmm 2.4.5 gtkmm 2.4.8 Matthew Hurne |
Don't know if gtkmm is much different at this place than pure gtk (that's what I use), but I use that sequence (modified, of course):
Code:
gtk_signal_connect (GTK_OBJECT (drawingArea), |
