pub struct ExpanderBuilder { /* private fields */ }
Expand description

A builder-pattern type to construct Expander objects.

Implementations

Create a new ExpanderBuilder.

Build the Expander.

Whether the label widget should fill all available horizontal space.

Note that this property is ignored since 3.20.

When this property is true, the expander will resize the toplevel widget containing the expander upon expanding and collapsing.

Space to put between the label and the child when the expander is expanded. This property is deprecated and ignored. Use margins on the child instead.

Whether to expand in both directions. Setting this sets both property::Widget::hexpand and property::Widget::vexpand

Available on crate feature v3_20 only.

Whether the widget should grab focus when it is clicked with the mouse.

This property is only relevant for widgets that can take focus.

Before 3.20, several widgets (GtkButton, GtkFileChooserButton, GtkComboBox) implemented this property individually.

Enables or disables the emission of signal::Widget::query-tooltip on widget. A value of true indicates that widget can have a tooltip, in this case the widget will be queried using signal::Widget::query-tooltip to determine whether it will provide a tooltip or not.

Note that setting this property to true for the first time will change the event masks of the GdkWindows of this widget to include leave-notify and motion-notify events. This cannot and will not be undone when the property is set to false again.

Whether to expand horizontally. See WidgetExt::set_hexpand().

Whether to use the property::Widget::hexpand property. See WidgetExt::is_hexpand_set().

Sets all four sides’ margin at once. If read, returns max margin on any side.

Margin on bottom side of widget.

This property adds margin outside of the widget’s normal size request, the margin will be added in addition to the size from WidgetExt::set_size_request() for example.

Margin on end of widget, horizontally. This property supports left-to-right and right-to-left text directions.

This property adds margin outside of the widget’s normal size request, the margin will be added in addition to the size from WidgetExt::set_size_request() for example.

Margin on start of widget, horizontally. This property supports left-to-right and right-to-left text directions.

This property adds margin outside of the widget’s normal size request, the margin will be added in addition to the size from WidgetExt::set_size_request() for example.

Margin on top side of widget.

This property adds margin outside of the widget’s normal size request, the margin will be added in addition to the size from WidgetExt::set_size_request() for example.

The requested opacity of the widget. See WidgetExt::set_opacity() for more details about window opacity.

Before 3.8 this was only available in GtkWindow

Sets the text of tooltip to be the given string, which is marked up with the [Pango text markup language][PangoMarkupFormat]. Also see Tooltip::set_markup().

This is a convenience property which will take care of getting the tooltip shown if the given string is not None: property::Widget::has-tooltip will automatically be set to true and there will be taken care of signal::Widget::query-tooltip in the default signal handler.

Note that if both property::Widget::tooltip-text and property::Widget::tooltip-markup are set, the last one wins.
