#[repr(transparent)]pub struct Paned { /* private fields */ }
Expand description
A widget with two panes, arranged either horizontally or vertically.
The division between the two panes is adjustable by the user by dragging a handle.
Child widgets are added to the panes of the widget with
set_start_child()
and set_end_child()
.
The division between the two children is set by default from the size
requests of the children, but it can be adjusted by the user.
A paned widget draws a separator between the two child widgets and a
small handle that the user can drag to adjust the division. It does not
draw any relief around the children or around the separator. (The space
in which the separator is called the gutter.) Often, it is useful to put
each child inside a Frame
so that the gutter appears as a
ridge. No separator is drawn if one of the children is missing.
Each child has two options that can be set, “resize” and “shrink”. If
“resize” is true then, when the Paned
is resized, that child will
expand or shrink along with the paned widget. If “shrink” is true, then
that child can be made smaller than its requisition by the user.
Setting “shrink” to false allows the application to set a minimum size.
If “resize” is false for both children, then this is treated as if
“resize” is true for both children.
The application can set the position of the slider as if it were set
by the user, by calling set_position()
.

Paned
has a main CSS node with name paned, and a subnode for
the separator with name separator. The subnode gets a .wide style
class when the paned is supposed to be wide.
In horizontal orientation, the nodes are arranged based on the text direction, so in left-to-right mode, :first-child will select the leftmost child, while it will select the rightmost child in RTL layouts.
Creating a paned widget with minimum sizes.

Signals
accept-position
Emitted to accept the current position of the handle when moving it using key bindings.
This is a keybinding signal.
The default binding for this signal is Return or Space.
Action
cancel-position
Emitted to cancel moving the position of the handle using key bindings.
The position of the handle will be reset to the value prior to moving it.
This is a keybinding signal.
The default binding for this signal is Escape.
Action
cycle-child-focus
Emitted to cycle the focus between the children of the paned.
This is a keybinding signal.
The default binding is F6.
Action
cycle-handle-focus
Emitted to cycle whether the paned should grab focus to allow the user to change position of the handle by using key bindings.
This is a keybinding signal.
The default binding for this signal is F8.
Action
move-handle
Emitted to move the handle with key bindings.
This is a keybinding signal.
Action
toggle-handle-focus
Emitted to accept the current position of the handle and then move focus to the next widget in the focus chain.
This is a keybinding signal.
The default binding is Tab.
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.
Action
query-tooltip
Emitted when the widgets 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.
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).
