Struct libhandy::ViewSwitcherBar

pub struct ViewSwitcherBar { /* private fields */ }

A view switcher action bar.

An action bar letting you switch between multiple views offered by a [gtk::Stack][crate::gtk::Stack], via an ViewSwitcher. It is designed to be put at the bottom of a window and to be revealed only on really narrow windows e.g. on mobile phones. It can’t be revealed if there are less than two pages.

ViewSwitcherBar is intended to be used together with ViewSwitcherTitle.

A common use case is to bind the reveal property to title-visible to automatically reveal the view switcher bar when the title label is displayed in place of the view switcher, as follows:

<object class="GtkWindow"/>
  <child type="titlebar">
    <object class="HdyHeaderBar">
      <property name="centering-policy">strict</property>
      <child type="title">
        <object class="HdyViewSwitcherTitle"
                id="view_switcher_title">
          <property name="stack">stack</property>
        </object>
      </child>
    </object>
  </child>
  <child>
    <object class="GtkBox">
      <child>
        <object class="GtkStack" id="stack"/>
      </child>
      <child>
        <object class="HdyViewSwitcherBar">
          <property name="stack">stack</property>
          <property name="reveal"
                    bind-source="view_switcher_title"
                    bind-property="title-visible"
                    bind-flags="sync-create"/>
        </object>
      </child>
    </object>
  </child>
</object>

expand

Whether to expand in both directions. Setting this sets both #GtkWidget:hexpand and #GtkWidget:vexpand

Readable | Writeable

focus-on-click

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.

Readable | Writeable

halign

How to distribute horizontal space if widget gets extra space, see #GtkAlign

Readable | Writeable

has-default

Readable | Writeable

has-focus

Readable | Writeable

has-tooltip

Enables or disables the emission of #GtkWidget::query-tooltip on @widget. A value of true indicates that @widget can have a tooltip, in this case the widget will be queried using #GtkWidget::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.

Readable | Writeable

height-request

Readable | Writeable

hexpand

Whether to expand horizontally. See gtk_widget_set_hexpand().

Readable | Writeable

hexpand-set

Whether to use the #GtkWidget:hexpand property. See gtk_widget_get_hexpand_set().

Readable | Writeable

is-focus

Readable | Writeable

margin

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

Readable | Writeable

margin-bottom

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 gtk_widget_set_size_request() for example.

Readable | Writeable

margin-end

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 gtk_widget_set_size_request() for example.

Readable | Writeable

margin-left

Margin on left 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 gtk_widget_set_size_request() for example.

Readable | Writeable

margin-right

Margin on right 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 gtk_widget_set_size_request() for example.

Readable | Writeable

margin-start

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 gtk_widget_set_size_request() for example.

Readable | Writeable

margin-top

opacity

The requested opacity of the widget. See gtk_widget_set_opacity() for more details about window opacity.

Before 3.8 this was only available in GtkWindow

Readable | Writeable

scale-factor

The scale factor of the widget. See gtk_widget_get_scale_factor() for more details about widget scaling.

The style of the widget, which contains information about how it will look (colors, etc).

Readable | Writeable

tooltip-markup

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

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

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

Readable | Writeable

tooltip-text

Sets the text of tooltip to be the given string.

Also see gtk_tooltip_set_text().
