/**
* SECTION:gtkradiobutton
* @Short_description: A choice from multiple check buttons
* @Title: GtkRadioButton
* @See_also: #GtkComboBox
*
* A single radio button performs the same basic function as a #GtkCheckButton,
* as its position in the object hierarchy reflects. It is only when multiple
* radio buttons are grouped together that they become a different user
* interface component in their own right.
*
* Every radio button is a member of some group of radio buttons. When one is
* selected, all other radio buttons in the same group are deselected. A
* #GtkRadioButton is one way of giving the user a choice from many options.
*
* Radio button widgets are created with gtk_radio_button_new(), passing %NULL
* as the argument if this is the first radio button in a group. In subsequent
* calls, the group you wish to add this button to should be passed as an
* argument. Optionally, gtk_radio_button_new_with_label() can be used if you
* want a text label on the radio button.
*
* Alternatively, when adding widgets to an existing group of radio buttons,
* use gtk_radio_button_new_from_widget() with a #GtkRadioButton that already
* has a group assigned to it. The convenience function
* gtk_radio_button_new_with_label_from_widget() is also provided.
*
* To retrieve the group a #GtkRadioButton is assigned to, use
* gtk_radio_button_get_group().
*
* To remove a #GtkRadioButton from one group and make it part of a new one,
* use gtk_radio_button_set_group().
*
* The group list does not need to be freed, as each #GtkRadioButton will remove
* itself and its list item when it is destroyed.
*
* # CSS nodes
*
* |[<!-- language="plain" -->
* radiobutton
* radio
* <child>
* ]|
*
* A GtkRadioButton with indicator (see gtk_toggle_button_set_mode()) has a
* main CSS node with name radiobutton and a subnode with name radio.
*
* |[<!-- language="plain" -->
* button.radio
* radio
* <child>
* ]|
*
* A GtkRadioButton without indicator changes the name of its main node
* to button and adds a .radio style class to it. The subnode is invisible
* in this case.
*
* ## How to create a group of two radio buttons.
*
* |[<!-- language="C" -->
* void create_radio_buttons (void) {
*
* GtkWidget *window, *radio1, *radio2, *box, *entry;
* window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
* box = gtk_box_new (GTK_ORIENTATION_VERTICAL, 2);
* gtk_box_set_homogeneous (GTK_BOX (box), TRUE);
*
* // Create a radio button with a GtkEntry widget
* radio1 = gtk_radio_button_new (NULL);
* entry = gtk_entry_new ();
* gtk_container_add (GTK_CONTAINER (radio1), entry);
*
*
* // Create a radio button with a label
* radio2 = gtk_radio_button_new_with_label_from_widget (GTK_RADIO_BUTTON (radio1),
2014-02-07 18:42:09 +00:00
* "Im the second radio button.");
*
* // Pack them into a box, then show all the widgets
* gtk_box_pack_start (GTK_BOX (box), radio1, TRUE, TRUE, 2);
* gtk_box_pack_start (GTK_BOX (box), radio2, TRUE, TRUE, 2);
* gtk_container_add (GTK_CONTAINER (window), box);
* gtk_widget_show_all (window);
* return;
* }
* ]|
*
* When an unselected button in the group is clicked the clicked button
* receives the #GtkToggleButton::toggled signal, as does the previously
* selected button.
* Inside the #GtkToggleButton::toggled handler, gtk_toggle_button_get_active()
* can be used to determine if the button has been selected or deselected.

Add new infrastructure for notifications of failed keyboard navigation and 2006-11-16 Michael Natterer <mitch@imendio.com> Add new infrastructure for notifications of failed keyboard navigation and navigation with restricted set of keys. The patch handles configurable beeping, navigating the GUI with cursor keys only (as in phone environments), and configurable wrap-around. Fixes bugs #322640, #70986, #318827, #334726, #334742 and #309291. * gtk/gtksettings.c: added properties gtk-keynav-cursor-only, gtk-keynav-wrap-around and gtk-error-bell. * gtk/gtkwidget.[ch]: added new signal "keynav-failed" and public API to emit it. Added New function gtk_widget_error_bell() which looks at the gtk-error-bell setting and calls gdk_window_beep() accordingly. * gtk/gtk.symbols: add the new widget symbols. * gtk/gtkcellrendereraccel.c * gtk/gtkimcontextsimple.c * gtk/gtkmenu.c * gtk/gtknotebook.c: use gtk_widget_error_bell() or look at the gtk-error-bell setting instead of calling gdk_display_beep() unconditionally. * gtk/gtkcombobox.c * gtk/gtkentry.c * gtk/gtkiconview.c * gtk/gtklabel.c * gtk/gtkmenushell.c * gtk/gtkspinbutton.c * gtk/gtktextview.c * gtk/gtktreeview.c: call gtk_widget_error_bell() on failed keynav. * gtk/gtkentry.c * gtk/gtklabel.c * gtk/gtkrange.c * gtk/gtktextview.c: consult gtk_widget_keynav_failed() on failed cursor navigation and leave the widget if it returns FALSE. * gtk/gtkmenushell.c * gtk/gtknotebook.c: only wrap around if gtk-keynav-wrap-around is TRUE. * gtk/gtkradiobutton.c: ask gtk_widget_keynav_failed() to decide whether to to wrap-around, and don't select active items on cursor navigation if gtk-keynav-cursor-only is TRUE. Should look at gtk-keynav-wrap-around too, will look into that.

reworked the redrawing heuristics somewhat, this fixed a bunch of existing Tue Jan 12 13:47:07 1999 Tim Janik <timj@gtk.org> * reworked the redrawing heuristics somewhat, this fixed a bunch of existing redrawing problems and majorly reduces overall redrawing needs during normal operation. basically we now only queue redraws when neccessary and much rely on the draw_area coalescing code in gtkwidget.c to optimize the queued portions. widgets will now upon reallocation only get redrawed if their allocation has changed. upon hide/show only the area allocated by the child will be queued for the parent, this has the side effect that parents which change their appearance in dependance on the numer of visible children have to keep track of their children's visiblity and eventually fully redraw themselves. this is a minor constrain with great benefits in terms of redraw reduction, and only got triggered by the notebook widget. * gtk/gtkwidget.c: (gtk_widget_queue_clear): don't bother if width and height == 0. (gtk_widget_queue_clear_child): new static function to queue a redraw of the area obscured by a child on a parent. (gtk_widget_queue_resize): queue_clear the widget if it is drawable. (gtk_widget_show): queue resize on the widget before showing. (gtk_widget_hide): queue resize on the widget after hiding. (gtk_widget_map): queue_draw the widget after mapping. (gtk_widget_unmap): queue_clear_child the widget. (gtk_widget_size_allocate): queue_clear_child and queue_draw if the widget's allocation changed. (gtk_widget_unparent): queue_clear_child so the parent redraws obscured portions. (gtk_widget_real_show): (gtk_widget_real_hide): (gtk_widget_real_map): (gtk_widget_real_unmap): (gtk_widget_real_size_allocate): don't bother with redraw queueing, descendants that override these functions don't do either and we handle all redrawing/resizing related stuff before or after the signal emission now. * gtk/gtkcontainer.c: (gtk_container_resize_children): don't bother about redrawing anymore since gtk_widget_size_allocate handles that for us now. * gtk/gtknotebook.h: * gtk/gtknotebook.c: added a flag have_visible_child to indicate whether we need to draw non child related portions at all, e.g. shadows etc. (gtk_notebook_draw): if have_visible_child changed, do a full paint instead of updating a small area only. Mon Jan 11 20:44:35 1999 Tim Janik <timj@gtk.org> * gtk/gtkstyle.c: changed gtk_style_apply_default_pixmap to gtk_style_apply_default_background which takes an extra argument copy_area to determine NO_WINDOW widget pixmap copying. changed callers accordingly. * gtk/gtktogglebutton.c: (gtk_toggle_size_allocate): (gtk_toggle_button_expose): (gtk_toggle_button_paint): avoid messing with our parent's window if toggle_button->draw_indicator == TRUE and we are a NO_WINDOW widget. * gtk/gtkcheckbutton.c (gtk_real_check_button_draw_indicator): draw the draw_indicator with GTK_STATE_ACTIVE if the toggle button is active. * gtk/check-n.xpm: * gtk/check-y.xpm: * gtk/testgtkrc: set pixmaps for ACTIVE and NORMAL check button bg_pixmaps.
