示例1: HandleDrag
void gResizerBar::HandleDrag(int diff) {
Fl_Scroll *grp = (Fl_Scroll*)parent();
int top = y();
int bot = y()+h();
// First pass: find widget directly above us with common edge
// Possibly clamp 'diff' if widget would get too small..
for (int t=0; t<grp->children(); t++) {
Fl_Widget *w = grp->child(t);
if ((w->y()+w->h()) == top) { // found widget directly above?
if ((w->h()+diff) < min_h) diff = w->h() - min_h; // clamp
w->resize(w->x(), w->y(), w->w(), w->h()+diff); // change height
break; // done with first pass
}
}
// Second pass: find widgets below us, move based on clamped diff
for (int t=0; t<grp->children(); t++) {
Fl_Widget *w = grp->child(t);
if (w->y() >= bot) // found widget below us?
w->resize(w->x(), w->y()+diff, w->w(), w->h()); // change position
}
// Change our position last
resize(x(),y()+diff,w(),h());
grp->init_sizes();
