void lxgui::gui::root::request_focus ( utils::observer_ptr< frame > receiver )

receiver The frame that requires focus

Note: This function will forward all keyboard events to the new receiver. This is useful to implement an edit box: the user can type letters using keys that can be bound to special actions in the game, and these should be prevented from happening. This can be achieved by calling this function and using the edit box as second argument, which will ensure that input events are only sent to the edit box exclusively.

	)

Start manually moving a region with the mouse.

Parameters

obj	The object to move
a	The reference anchor
constraint	The constraint axis if any
apply_constraint_func	Optional function to implement further constraints

Note: Movement is handled by the root, you don't need to do anything except calling stop_moving() when you are done.

Definition at line 303 of file gui_root.cpp.

◆ start_sizing()

void lxgui::gui::root::start_sizing	(	utils::observer_ptr< region >	obj,
		point	p
	)

Starts manually resizing a region with the mouse.

Parameters

obj	The object to resize
p	The sizing point

updates this root and its regions.

Parameters

delta The time elapsed since the last call
