Hi all,
I made my own class TaskDrawingPanel inherited from Fl_Widget and put it into a
Fl_Scroll instance, which in turn is a child of my main window.
The draw method of TaskDrawingPanel does nothing else then drawing a rectangle.
My Problem: the rectangle doesn't redraw properly after scrolling.
The main method looks like so:
int main(int argc, char **argv) {
Fl_Double_Window mainWin( 50, 50, 400, 400, "TaskOrganiser" );
mainWin.box( FL_NO_BOX );
Fl_Scroll scroll( 0, 0, 400, 400, "" );
scroll.type( Fl_Scroll::BOTH );
TaskDrawingPanel panel( 0,0, 500, 500, "Panel" );
scroll.callback( (Fl_Callback*)resize_callback, (void*)("test") );
scroll.end();
mainWin.resizable( scroll );
mainWin.show( argc, argv );
return Fl::run();
}
And that's the TaskDrawingPanel class:
class TaskDrawingPanel : public Fl_Widget
{
void draw() {
draw_box();
fl_rect( 20, 20, 100, 100, FL_RED );
}
public:
TaskDrawingPanel(int X,int Y,int W,int H,const char* L) :
Fl_Widget(X,Y,W,H,L) {
align(FL_ALIGN_TOP);
box(FL_FLAT_BOX);
color(FL_WHITE);
}
virtual ~TaskDrawingPanel() {}

private:
};
