Struct gtk4::FlowBox

source ·
pub struct FlowBox { /* private fields */ }
Expand description

A FlowBox puts child widgets in reflowing grid.

For instance, with the horizontal orientation, the widgets will be arranged from left to right, starting a new row under the previous row when necessary. Reducing the width in this case will require more rows, so a larger height will be requested.

Likewise, with the vertical orientation, the widgets will be arranged from top to bottom, starting a new column to the right when necessary. Reducing the height will require more columns, so a larger width will be requested.

The size request of a FlowBox alone may not be what you expect; if you need to be able to shrink it along both axes and dynamically reflow its children, you may have to wrap it in a ScrolledWindow to enable that.

The children of a FlowBox can be dynamically sorted and filtered.

Although a FlowBox must have only FlowBoxChild children, you can add any kind of widget to it via insert(), and a FlowBoxChild widget will automatically be inserted between the box and the widget.

Also see ListBox.

§CSS nodes

╰── [rubberband]

FlowBox uses a single CSS node with name flowbox. FlowBoxChild uses a single CSS node with name flowboxchild. For rubberband selection, a subnode with name rubberband is used.

§Accessibility

FlowBox uses the AccessibleRole::Grid role, and FlowBoxChild uses the AccessibleRole::GridCell role.

§Signals

§activate-cursor-child

Emitted when the user activates the @box_.

This is a keybinding signal.

Action

§child-activated

Emitted when a child has been activated by the user.

§move-cursor

Emitted when the user initiates a cursor movement.

This is a keybinding signal. Applications should not connect to it, but may emit it with g_signal_emit_by_name() if they need to control the cursor programmatically.

The default bindings for this signal come in two variants, the variant with the Shift modifier extends the selection, the variant without the Shift modifier does not. There are too many key combinations to list them all here.

  • , , , move by individual children
  • Home, End move to the ends of the box
  • PgUp, PgDn move vertically by pages

Action

§select-all

Emitted to select all children of the box, if the selection mode permits it.

This is a keybinding signal.

The default bindings for this signal is Ctrl-a.

Action

§selected-children-changed

Emitted when the set of selected children changes.

Use FlowBox::selected_foreach() or FlowBox::selected_children() to obtain the selected children.

§toggle-cursor-child

Emitted to toggle the selection of the child that has the focus.

This is a keybinding signal.

The default binding for this signal is Ctrl-Space.

Action

§unselect-all

Emitted to unselect all children of the box, if the selection mode permits it.

This is a keybinding signal.

The default bindings for this signal is Ctrl-Shift-a.

Action

Widget

§destroy

Signals that all holders of a reference to the widget should release the reference that they hold.

May result in finalization of the widget if all references are released.

This signal is not suitable for saving widget state.

§direction-changed

Emitted when the text direction of a widget changes.

§hide

Emitted when @widget is hidden.

§keynav-failed

Emitted if keyboard navigation fails.

See WidgetExt::keynav_failed() for details.

§map

Emitted when @widget is going to be mapped.

A widget is mapped when the widget is visible (which is controlled with visible) and all its parents up to the toplevel widget are also visible.

The ::map signal can be used to determine whether a widget will be drawn, for instance it can resume an animation that was stopped during the emission of unmap.

§mnemonic-activate

Emitted when a widget is activated via a mnemonic.

The default handler for this signal activates @widget if @group_cycling is false, or just makes @widget grab focus if @group_cycling is true.

§move-focus

Emitted when the focus is moved.

The ::move-focus signal is a keybinding signal.

The default bindings for this signal are Tab to move forward, and Shift+Tab to move backward.

Action

§query-tooltip

Emitted when the widget’s tooltip is about to be shown.

This happens when the has-tooltip property is true and the hover timeout has expired with the cursor hovering “above” @widget; or emitted when @widget got focus in keyboard mode.

Using the given coordinates, the signal handler should determine whether a tooltip should be shown for @widget. If this is the case true should be returned, false otherwise. Note that if @keyboard_mode is true, the values of @x and @y are undefined and should not be used.

The signal handler is free to manipulate @tooltip with the therefore destined function calls.

§realize

Emitted when @widget is associated with a gdk::Surface.

This means that WidgetExt::realize() has been called or the widget has been mapped (that is, it is going to be drawn).

§show

Emitted when @widget is shown.

§state-flags-changed

Emitted when the widget state changes.

See WidgetExt::state_flags().

§unmap

Emitted when @widget is going to be unmapped.

A widget is unmapped when either it or any of its parents up to the toplevel widget have been set as hidden.

As ::unmap indicates that a widget will not be shown any longer, it can be used to, for example, stop an animation on the widget.

§unrealize

Emitted when the gdk::Surface associated with @widget is destroyed.

This means that WidgetExt::unrealize() has been called or the widget has been unmapped (that is, it is going to be hidden).

This method returns an instance of FlowBoxBuilder which can be used to create FlowBox objects.

source

pub fn append(&self, child: &impl IsA<Widget>)

Available on crate feature v4_6 only.

The contents of @self are cleared and then filled with widgets that represent items from @model. @self is updated whenever @model changes. If @model is None, @self is left empty.

It is undefined to add or remove widgets directly (for example, with insert()) while @self is bound to a model.

Note that using a model is incompatible with the filtering and sorting functionality in FlowBox. When using a model, filtering and sorting should be implemented by the model.

By setting a filter function on the @self one can decide dynamically which of the children to show.

For instance, to implement a search function that only shows the children matching the search terms.

The @filter_func will be called for each child after the call, and it will continue to be called each time a child changes (via FlowBoxChildExt::changed()) or when invalidate_filter() is called.

Note that using a filter function is incompatible with using a model (see bind_model()).

§filter_func

callback that lets you filter which children to show

source
