Constructor Details

FontDialogButton

public FontDialogButton(MemorySegment address)

Create a FontDialogButton proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

FontDialogButton

public FontDialogButton(@Nullable
 @Nullable FontDialog dialog)

Creates a new GtkFontDialogButton with the given GtkFontDialog.

You can pass NULL to this function and set a GtkFontDialog later. The button will be insensitive until that happens.

Parameters:

dialog - the GtkFontDialog to use

Since:

4.10

FontDialogButton

public FontDialogButton()

Creates a new FontDialogButton.

Method Details

getType

public static Type getType()

Get the GType of the FontDialogButton class

Returns:

the GType

asParent

protected FontDialogButton asParent()

Returns this instance as if it were its parent type. This is mostly synonymous to the Java super keyword, but will set the native typeclass function pointers to the parent type. When overriding a native virtual method in Java, "chaining up" with super.methodName() doesn't work, because it invokes the overridden function pointer again. To chain up, call asParent().methodName(). This will call the native function pointer of this virtual method in the typeclass of the parent type.

Overrides:

asParent in class Widget

getDialog

public FontDialog getDialog()

Returns the GtkFontDialog of this FontDialogButton.

Returns:

the GtkFontDialog

Since:

4.10

getFontDesc

public FontDescription getFontDesc()

Returns the font of the button.

This function is what should be used to obtain the font that was chosen by the user. To get informed about changes, listen to "notify::font-desc".

getFontFeatures

public String getFontFeatures()

Returns the font features of the button.

This function is what should be used to obtain the font features that were chosen by the user. To get informed about changes, listen to "notify::font-features".

Note that the button will only let users choose font features if Gtk.FontDialogButton:level is set to GTK_FONT_LEVEL_FEATURES.

Returns:

the font features

Since:

4.10

getLanguage

public Language getLanguage()

Returns the language that is used for font features.

Returns:

the language

Since:

4.10

getLevel
