A fix added to Fl_Group.H not by me but by Sebastian Hollington. It makes
the two clip_children functions public instead of protected to remove a
compile error.
The relevant lines are shown below and the modified Fl_Group.H is
attached.
// Line 53 in Fl_Group class
void clip_children(int c) { if (c) set_flag(CLIP_CHILDREN); else
clear_flag(CLIP_CHILDREN); }
int clip_children() { return (flags() & CLIP_CHILDREN) != 0; }
I have tested this fix with the following code in Ubuntu 8.04 but it
should apply to all OS's.
// "clip_children.cxx"
#include <FL/Fl.H>
#include <FL/Fl_Double_Window.H>
#include <FL/Fl_Box.H>
#include <FL/fl_draw.H>
class Application : public Fl_Double_Window
{
Fl_Box *bx; // Child box widget
public:
Application(int w, int h, const char *l, int argc, char *argv[]);
};
Application::Application(int w, int h, const char *l, int argc, char
*argv[])
: Fl_Double_Window(w, h, l)
{
box(FL_DOWN_BOX); // Add 2 pixels border
color(FL_WHITE);
begin();
bx = new Fl_Box(0,0,100, 400);
bx->box(FL_FLAT_BOX);
bx->color((Fl_Color) FL_RED);
end();
resizable(this);
show(argc, argv);
}
int main (int argc, char ** argv)
{
Application myApp(500, 300, "My App", argc, argv);
// Fl_Group.H:53: error: âvoid Fl_Group::clip_children(int)â is
protected
myApp.clip_children(true);
return(Fl::run());
}
