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

FontDialogButton

public FontDialogButton()

Calls FontDialogButton(org.gnome.gtk.FontDialog) with dialog = null

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

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".

Returns:

the font

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

getLanguage

public Language getLanguage()

Returns the language that is used for font features.

Returns:

the language

getLevel

public FontLevel getLevel()

Returns the level of detail at which this dialog lets the user select fonts.

Returns:

the level of detail

getUseFont

public boolean getUseFont()

Returns whether the selected font is used in the label.

Returns:

whether the selected font is used in the label

getUseSize

public boolean getUseSize()

Returns whether the selected font size is used in the label.

Returns:

whether the selected font size is used in the label

setDialog

public void setDialog(FontDialog dialog)

Sets a GtkFontDialog object to use for creating the font chooser dialog that is presented when the user clicks the button.

Parameters:

dialog - the new GtkFontDialog

setFontDesc

public void setFontDesc(FontDescription fontDesc)

Sets the font of the button.

Parameters:

fontDesc - the new font

setFontFeatures

public void setFontFeatures(@Nullable
 @Nullable String fontFeatures)

Sets the font features of the button.

Parameters:

fontFeatures - the font features

setLanguage

public void setLanguage(@Nullable
 @Nullable Language language)

Sets the language to use for font features.

Parameters:

language - the new language

setLevel

public void setLevel(FontLevel level)

Sets the level of detail at which this dialog lets the user select fonts.

Parameters:

level - the level of detail

setUseFont

public void setUseFont(boolean useFont)

If useFont is TRUE, the font name will be written using the selected font.

Parameters:

useFont - If TRUE, font name will be written using the chosen font

setUseSize

public void setUseSize(boolean useSize)

If useSize is TRUE, the font name will be written using the selected font size.

Parameters:

useSize - If TRUE, font name will be written using the chosen font size

onActivate

public SignalConnection<FontDialogButton.ActivateCallback> onActivate(FontDialogButton.ActivateCallback handler)

Emitted when the font dialog button is activated.

The ::activate signal on GtkFontDialogButton is an action signal and emitting it causes the button to pop up its dialog.

Parameters:

handler - the signal handler

Returns:

a signal handler ID to keep track of the signal connection

See Also:

• FontDialogButton.ActivateCallback.run()

emitActivate

public void emitActivate()

Emits the "activate" signal. See onActivate(org.gnome.gtk.FontDialogButton.ActivateCallback).

builder

public static FontDialogButton.Builder<? extends FontDialogButton.Builder> builder()

A FontDialogButton.Builder object constructs a FontDialogButton with the specified properties. Use the various set...() methods to set properties, and finish construction with FontDialogButton.Builder.build().
