I'm looking at how to make fltk widgets resize fonts along with it's size and I
miss a function that I'll call "get_full_size" I think it'll facilitate some
layout management for instance Fl_Pack doesn't resize at all like other
widgets, I implemented and tested this function with 1.3 trunk:
/**
Returns the full rectangle occupied by a widget plus it's external label if any
*/
#ifndef intmax
int intmax(int a, int b) {return a > b ? a : b;};
#endif
void Fl_Widget::get_full_size(int &full_x, int &full_y, int &full_w, int
&full_h) {
int W = 0, H = 0;
label_.measure(W, H);
W += 5; // Add a little to the size of the label to cover overflow
H += 5;
if (align() && !(align() & FL_ALIGN_INSIDE)) {
// If the label is not inside the widget, compute the location of
// the label and redraw the window within that bounding box...
if (align() & FL_ALIGN_BOTTOM) {
full_x = x();
full_y = y();
full_w = intmax(w(), W);
full_h = h() + H;
return;
} else if (align() & FL_ALIGN_TOP) {
full_x = x();
full_y = y() - H;
full_w = intmax(w(), W);
full_h = h() + H;
return;
} else if (align() & FL_ALIGN_LEFT) {
full_x = x() - W;
full_y = y();
full_w = w() + W;
full_h = intmax(h(), H);
return;
} else if (align() & FL_ALIGN_RIGHT) {
full_x = x();
full_y = y();
full_w = w() + W;
full_h = intmax(h(), H);
return;
}
}
// The label is inside the widget, so just return the widget itself
//plus adjustments in case the label overflow
full_x = x();
full_y = y();
full_w = intmax(w(), W);
full_h = intmax(h(), H);
}
