Struct gtk::TreeViewBuilder[][src]

pub struct TreeViewBuilder { /* fields omitted */ }
Expand description

A builder-pattern type to construct TreeView objects.

Implementations

Create a new TreeViewBuilder.

Build the TreeView.

The activate-on-single-click property specifies whether the “row-activated” signal will be emitted after a single click.

Setting the ::fixed-height-mode property to true speeds up TreeView by assuming that all rows have the same height. Only enable this option if all rows are the same height. Please see TreeViewExt::set_fixed_height_mode() for more information on this option.

Enables or disables the hover expansion mode of tree_view. Hover expansion makes rows expand or collapse if the pointer moves over them.

This mode is primarily intended for treeviews in popups, e.g. in ComboBox or EntryCompletion.

Enables or disables the hover selection mode of tree_view. Hover selection makes the selected row follow the pointer. Currently, this works only for the selection modes SelectionMode::Single and SelectionMode::Browse.

This mode is primarily intended for treeviews in popups, e.g. in ComboBox or EntryCompletion.

Extra indentation for each level.

true if the view has expanders.

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

This is supported 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.

How to distribute vertical space if widget gets extra space, see Align

Whether to expand vertically. See WidgetExt::set_vexpand().

Whether to use the property::Widget::vexpand property. See WidgetExt::is_vexpand_set().

Horizontal Adjustment of the scrollable widget. This adjustment is shared between the scrollable widget and its parent.

Determines whether horizontal scrolling should start once the scrollable widget is allocated less than its minimum width or less than its natural width.

Verical Adjustment of the scrollable widget. This adjustment is shared between the scrollable widget and its parent.

Determines whether vertical scrolling should start once the scrollable widget is allocated less than its minimum height or less than its natural height.
