Methods

• FontButton (fontname = null)

  Creates a new font picker widget.

  • @p fontname is Name of font to display in font chooser dialog.

• toNativeHandle (Source)

  Normalizes a constructor argument into a raw pointer carrier. Accepts a raw NativeHandle, a raw NativeBuffer returned from fn.call(...), another generated wrapper exposing handle(), or null. Returns null when the argument carries no pointer.

  • @p Source is the raw handle, raw buffer, wrapper, or null.
  • @r A raw pointer carrier or null when no pointer is present.

• getLib ()

  Returns the opened native library for this generated wrapper.

  • @r The opened native library.

• handle ()

  Returns the wrapped NativeHandle.

  • @r The wrapped NativeHandle.

• isNull ()

  Returns true when the wrapped handle is null.

  • @r A bool.

• describe ()

  Returns a small string for debugging generated wrappers.

  • @r A string.

• asWidget ()

  Wraps this handle as Widget.

  • @r A Widget object.

• asAccessible ()

  Wraps this handle as Accessible.

  • @r A Accessible object.

• asBuildable ()

  Wraps this handle as Buildable.

  • @r A Buildable object.

• asConstraintTarget ()

  Wraps this handle as ConstraintTarget.

  • @r A ConstraintTarget object.

• asFontChooser ()

  Wraps this handle as FontChooser.

  • @r A FontChooser object.

• connectSignal (string Name, CallbackObj)

  Connects one generated callback wrapper to a named signal.

  • @p Name is the signal name.
  • @p CallbackObj is the generated callback wrapper to connect.
  • @r The connected handler id.

• disconnectSignalHandler (int HandlerId)

  Disconnects one retained signal handler id.

  • @p HandlerId is the signal handler id to disconnect.
  • @r None.

• setOnActivate (callback Fn, UserData = null)

  Emitted to when the font button is activated. The ::activate signal on GtkFontButton is an action signal and emitting it causes the button to present its dialog.

  • @p Fn is the Aussom callback.
  • @p Fn is called with (FontButton Self).
  • @p UserData is retained and passed through to the generated callback wrapper when provided.
  • @r The connected handler id.

• setOnFontset (callback Fn, UserData = null)

  Emitted when the user selects a font. When handling this signal, use [method@Gtk.FontChooser.get_font] to find out which font was just selected. Note that this signal is only emitted when the user changes the font. If you need to react to programmatic font changes as well, use the notify::font signal.

  • @p Fn is the Aussom callback.
  • @p Fn is called with (FontButton Self).
  • @p UserData is retained and passed through to the generated callback wrapper when provided.
  • @r The connected handler id.

• getProperty (string Name)

  Reads one generated property by name.

• setProperty (string Name, Value)

  Writes one generated property by name.

• setModal (bool Value)

  Whether the font chooser dialog should be modal.

  • @p Value is the new property value.
  • @r None.

• setTitle (string Value)

  The title of the font chooser dialog.

  • @p Value is the new property value.

• setUsefont (bool Value)

  Whether the buttons label will be drawn in the selected font.

  • @p Value is the new property value.
  • @r None.

• setUsesize (bool Value)

  Whether the buttons label will use the selected font size.

  • @p Value is the new property value.
  • @r None.

• get_modal ()

  Gets whether the dialog is modal.

• get_title ()

  Retrieves the title of the font chooser dialog.

• get_use_font ()

  Returns whether the selected font is used in the label.

• get_use_size ()

  Returns whether the selected size is used in the label.

• set_modal (bool modal)

  Sets whether the dialog should be modal.

  • @p modal is %TRUE to make the dialog modal.
  • @r None.

• set_title (string title)

  Sets the title for the font chooser dialog.

  • @p title is a string containing the font chooser dialog title.
  • @r None.

• set_use_font (bool use_font)

  If @use_font is %TRUE, the font name will be written using the selected font.

  • @p use_font is If %TRUE, font name will be written using font chosen..
  • @r None.

• set_use_size (bool use_size)

  If @use_size is %TRUE, the font name will be written using the selected size.

  • @p use_size is If %TRUE, font name will be written using the selected size..
  • @r None.
