I am trying to understand goocanvasmm by examining the examples in
goocanvasmm-0.14.0
In the example called 'text' I have added two lines to window.cc as
follows:
void ExampleWindow::update_label()
{
cairo_matrix_t * pMatrix = m_text->property_transform(); // line A
double x0 = pMatrix->x0; // line B
std::stringstream str;
...
etc
My aim is to output the components of the transform matrix so that I can
understand what is happening to it.
The program compiles and links in CDT with no reported error.
If I comment out line B, it runs OK and, as expected, gives the same
output as the original example.
With line B however, the program terminates and outputs a <terminated>
message without opening a window.
It does not report an error.
I should be very grateful if anyone can throw any light on this.
