Trait containing all ToolButton methods.

Implementors

MenuToolButton, ToggleToolButton, ToolButton

Required Methods

Returns the name of the themed icon for the tool button, see set_icon_name().

Returns

the icon name or None if the tool button has no themed icon

Return the widget used as icon widget on self. See set_icon_widget().

Returns

The widget used as icon on self, or None.

Returns the label used by the tool button, or None if the tool button doesn’t have a label. or uses a the label from a stock item. The returned string is owned by GTK+, and must not be modified or freed.

Returns

The label, or None

Returns the widget used as label on self. See set_label_widget().

Returns

The widget used as label on self, or None.

Returns whether underscores in the label property are used as mnemonics on menu items on the overflow menu. See set_use_underline().

Returns

true if underscores in the label property are used as mnemonics on menu items on the overflow menu.

Sets the icon for the tool button from a named themed icon. See the docs for IconTheme for more details. The property::ToolButton::icon-name property only has an effect if not overridden by non-None property::ToolButton::label-widget, property::ToolButton::icon-widget and property::ToolButton::stock-id properties.

icon_name

the name of the themed icon

Sets icon as the widget used as icon on self. If icon_widget is None the icon is determined by the property::ToolButton::stock-id property. If the property::ToolButton::stock-id property is also None, self will not have an icon.

icon_widget

the widget used as icon, or None

Sets label as the label used for the tool button. The property::ToolButton::label property only has an effect if not overridden by a non-None property::ToolButton::label-widget property. If both the property::ToolButton::label-widget and property::ToolButton::label properties are None, the label is determined by the property::ToolButton::stock-id property. If the property::ToolButton::stock-id property is also None, self will not have a label.

label

a string that will be used as label, or None.

Sets label_widget as the widget that will be used as the label for self. If label_widget is None the property::ToolButton::label property is used as label. If property::ToolButton::label is also None, the label in the stock item determined by the property::ToolButton::stock-id property is used as label. If property::ToolButton::stock-id is also None, self does not have a label.

label_widget

the widget used as label, or None

If set, an underline in the label property indicates that the next character should be used for the mnemonic accelerator key in the overflow menu. For example, if the label property is “_Open” and use_underline is true, the label on the tool button will be “Open” and the item on the overflow menu will have an underlined “O”.

Labels shown on tool buttons never have mnemonics on them; this property only affects the menu item on the overflow menu.

use_underline

whether the button label has the form “_Open”

This signal is emitted when the tool button is clicked with the mouse or activated with the keyboard.
