Interfaces

GtkWidget implements AtkImplementorIface and GtkBuildable.

Interface Derivations

GtkWidget is required by GtkCellEditable, GtkFileChooser and GtkToolShell.

Detailed Description

GtkWidget is the base class all widgets in GTK+ derive from. It manages the widget lifecycle, states and style. GtkWidget introduces style properties - these are basically object properties that are stored not on the object, but in the style object associated to the widget. Style properties are set in resource files. This mechanism is used for configuring such things as the location of the scrollbar arrows through the theme, giving theme authors more control over the look of applications without the need to write a theme engine in C.

Use gtkWidgetClassInstallStyleProperty to install style properties for a widget class, gtkWidgetClassFindStyleProperty or gtkWidgetClassListStyleProperties to get information about existing style properties and gtkWidgetStyleGetProperty, gtkWidgetStyleGet or gtkWidgetStyleGetValist() to obtain the value of a style property.

GtkWidget as GtkBuildable The GtkWidget implementation of the GtkBuildable interface supports a custom <accelerator> element, which has attributes named key, modifiers and signal and allows to specify accelerators.

A UI definition fragment specifying an accelerator

<object class="GtkButton">
  <accelerator key="q" modifiers="GDK_CONTROL_MASK" signal="clicked"/>
</object>

<object class="GtkButton" id="label1"/>
  <property name="label">I am a Label for a Button</property>
</object>
<object class="GtkButton" id="button1">
  <accessibility>
    <action action_name="click" translatable="yes">Click the button.</action>
    <relation target="label1" type="labelled-by"/>
  </accessibility>
  <child internal-child="accessible">
    <object class="AtkObject" id="a11y-button1">
      <property name="AtkObject::name">Clickable Button</property>
    </object>
  </child>
</object>
