Fl_Widget.H
Fl_Widget, Fl_Label classes .
Fl_End
This is a dummy class that allows you to end a Fl_Group in a constructor list of a class:
Definition: Fl_Group.H:218
Fl_End::Fl_End
Fl_End()
All it does is calling Fl_Group::current()->end()
Definition: Fl_Group.H:221
Fl_Group
The Fl_Group class is the FLTK container widget.
Definition: Fl_Group.H:41
Fl_Group::end
void end()
Exactly the same as current(this->parent()).
Definition: Fl_Group.cxx:75
Fl_Group::add_resizable
void add_resizable(Fl_Widget &o)
Adds a widget to the group and makes it the resizable widget.
Definition: Fl_Group.H:156
Fl_Group::add
void add(Fl_Widget *o)
See void Fl_Group::add(Fl_Widget &w)
Definition: Fl_Group.H:98
Fl_Group::focus
void focus(Fl_Widget *W)
Definition: Fl_Group.H:188
Fl_Group::child
Fl_Widget * child(int n) const
Returns array()[n].
Definition: Fl_Group.H:79
Fl_Group::children
int children() const
Returns how many child widgets the group has.
Definition: Fl_Group.H:75
Fl_Group::_ddfdesign_kludge
Fl_Widget *& _ddfdesign_kludge()
This is for forms compatibility only.
Definition: Fl_Group.H:191
Fl_Group::remove
void remove(Fl_Widget *o)
Removes the widget o from the group.
Definition: Fl_Group.H:111
Fl_Group::resizable
void resizable(Fl_Widget &o)
See void Fl_Group::resizable(Fl_Widget *box)
Definition: Fl_Group.H:117
Fl_Group::clip_children
void clip_children(int c)
Controls whether the group widget clips the drawing of child widgets to its bounding box.
Definition: Fl_Group.H:168
Fl_Group::clip_children
unsigned int clip_children()
Returns the current clipping mode.
Definition: Fl_Group.H:176
Fl_Group::insert
void insert(Fl_Widget &o, Fl_Widget *before)
This does insert(w, find(before)).
Definition: Fl_Group.H:104
Fl_Group::resizable
Fl_Widget * resizable() const
See void Fl_Group::resizable(Fl_Widget *box)
Definition: Fl_Group.H:152
Fl_Group::as_group
virtual Fl_Group * as_group()
Returns an Fl_Group pointer if this widget is an Fl_Group.
Definition: Fl_Group.H:179
Fl_Group::current
static Fl_Group * current()
Returns the currently active group.
Definition: Fl_Group.cxx:84
Fl_Group::resizable
void resizable(Fl_Widget *o)
