Struct gtk4::Paned [−][src]
pub struct Paned(_);Expand description
Paned has 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().
CSS nodes
paned
├── <child>
├── separator[.wide]
╰── <child>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.

Implementations
Creates a new builder-pattern struct instance to construct Paned objects.
This method returns an instance of PanedBuilder which can be used to create Paned objects.
Sets the position of the divider between the two panes.
position
pixel position of divider, a negative value means that the position is unset
Sets whether the separator should be wide.
wide
the new value for the property::Paned::wide-handle property
The largest possible value for the position property.
This property is derived from the size and shrinkability of the widget’s children.
The smallest possible value for the position property.
This property is derived from the size and shrinkability of the widget’s children.
true if the position property has been set.
true if the position property has been set.

pub fn connect_accept_position<F: Fn(&Self) -> bool + 'static>(
&self,
f: F
) -> SignalHandlerId
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.

pub fn connect_cancel_position<F: Fn(&Self) -> bool + 'static>(
&self,
f: F
) -> SignalHandlerId
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.

pub fn connect_cycle_child_focus<F: Fn(&Self, bool) -> bool + 'static>(
&self,
f: F
) -> SignalHandlerId
Emitted to cycle the focus between the children of the paned.
This is a keybinding signal.
The default binding is F6.
reversed
whether cycling backward or forward

&self,
f: F
) -> SignalHandlerId
pub fn connect_cycle_handle_focus<F: Fn(&Self, bool) -> bool + 'static>(
&self,
f: F
) -> SignalHandlerId
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.

pub fn connect_toggle_handle_focus<F: Fn(&Self) -> bool + 'static>(
&self,
f: F
) -> SignalHandlerId
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.
