* @Short_description: Deprecated dialog box for selecting a color
|
||
* @Title: GtkColorSelectionDialog
|
||
*
|
||
* The #GtkColorSelectionDialog provides a standard dialog which
|
||
* allows the user to select a color much like the #GtkFileChooserDialog
|
||
* provides a standard dialog for file selection.
|
||
*
|
||
* Use gtk_color_selection_dialog_get_color_selection() to get the
|
||
* #GtkColorSelection widget contained within the dialog. Use this widget
|
||
* and its gtk_color_selection_get_current_color()
|
||
* function to gain access to the selected color. Connect a handler
|
||
* for this widget’s #GtkColorSelection::color-changed signal to be notified
|
||
* when the color changes.
|
||
*
|
||
* # GtkColorSelectionDialog as GtkBuildable # {#GtkColorSelectionDialog-BUILDER-UI}
|
||
*
|
||
* The GtkColorSelectionDialog implementation of the GtkBuildable interface
|
||
* exposes the embedded #GtkColorSelection as internal child with the
|
||
* name “color_selection”. It also exposes the buttons with the names
|
||
* “ok_button”, “cancel_button” and “help_button”.
