Title
Body
I currently have a program that draws lines and rectangles. void mousePressEvent(QMouseEvent *event); void mouseReleaseEvent(QMouseEvent *event); void mouseMoveEvent(QMouseEvent *event); I use mouseMoveEvent to draw temporary preview of a line and when i release i draw the actual line. What I would like to know is how can i make mouseMoveEvent work work only when i have the left mouse button pressed down. I tried the following but then the whole function stops working. void mouseMoveEvent(QMouseEvent *event) { if(event->button() == Qt::LeftButton) { //do stuff } } but then the function doesn't do anything. Any assistance would be much appreciated
