MarkAttributes

Provided Methods§

source

fn background(&self) -> Option<RGBA>

Stores background color in background.

Returns

whether background color for self was set.

`background`

a gdk::RGBA.

source

fn gicon(&self) -> Option<Icon>

Gets a gio::Icon to be used as a base for rendered icon. Note that the icon can be None if it wasn’t set earlier.

Returns

An icon. The icon belongs to self and should not be unreffed.

source

fn icon_name(&self) -> Option<GString>

Gets a name of an icon to be used as a base for rendered icon. Note that the icon name can be None if it wasn’t set earlier.

Returns

An icon name. The string belongs to self and should not be freed.

source

fn pixbuf(&self) -> Option<Pixbuf>

Gets a gdk_pixbuf::Pixbuf to be used as a base for rendered icon. Note that the pixbuf can be None if it wasn’t set earlier.

Returns

A pixbuf. The pixbuf belongs to self and should not be unreffed.

source

fn tooltip_markup(&self, mark: &impl IsA<Mark>) -> Option<GString>

Queries for a tooltip by emitting a query-tooltip-markup signal. The tooltip may contain a markup.

`mark`

a Mark.

Returns

A tooltip. The returned string should be freed by using g_free() when done with it.

source

fn tooltip_text(&self, mark: &impl IsA<Mark>) -> Option<GString>

Queries for a tooltip by emitting a query-tooltip-text signal. The tooltip is a plain text.

`mark`

a Mark.

Returns

A tooltip. The returned string should be freed by using g_free() when done with it.

source

fn render_icon(&self, widget: &impl IsA<Widget>, size: i32) -> Option<Pixbuf>

Renders an icon of given size. The base of the icon is set by the last call to one of: set_pixbuf(), set_gicon() or set_icon_name(). size cannot be lower than 1.

widget of which style settings may be used.
