Virtual method to be implemented by the user. Returns whether [method _gui_input] should not be called for children controls outside this control's rectangle. Input will be clipped to the Rect of this [Control]. Similar to [member rect_clip_content], but doesn't affect visibility.

Virtual method to be implemented by the user. Returns the minimum size for this control. Alternative to [member rect_min_size] for controlling minimum size via code. The actual minimum size will be the max value of these two (in each axis separately).

Replaces Godot 2's [code]_input_event[/code].
Virtual method to be implemented by the user. Use this method to process and accept inputs on UI elements. See [method accept_event].
Example: clicking a control.
[codeblock]
func _gui_input(event):
if event is InputEventMouseButton:
if event.button_index == BUTTON_LEFT and event.pressed:
print("I've been clicked D:")
[/codeblock]
The event won't trigger if:
* clicking outside the control (see [method has_point]);
* control has [member mouse_filter] set to [member MOUSE_FILTER_IGNORE];
* control is obstructed by another [Control] on top of it, which doesn't have [member mouse_filter] set to [member MOUSE_FILTER_IGNORE];
* control's parent has [member mouse_filter] set to [member MOUSE_FILTER_STOP] or has accepted the event;
* it happens outside parent's rectangle and the parent has either [member rect_clip_content] or [member _clips_input] enabled.

<argument index="0" name="for_text" type="String">
</argument>
<description>
Virtual method to be implemented by the user. Returns a [Control] node that should be used as a tooltip instead of the default one. Use [code]for_text[/code] parameter to determine what text the tooltip should contain (likely the contents of [member hint_tooltip]).
The returned node must be of type [Control] or Control-derieved. It can have child nodes of any type. It is freed when the tooltip disappears, so make sure you always provide a new instance, not e.g. a node from scene. When null or non-Control node is returned, the default tooltip will be used instead.
[b]Note:[/b] The tooltip is shrunk to miminal size. If you want to ensure it's fully visible, you might want to set its [member rect_min_size] to some non-zero value.
Example of usage with custom-constructed node:
[codeblock]
func _make_custom_tooltip(for_text):
var label = Label.new()
label.text = for_text
return label
[/codeblock]
Example of usage with custom scene instance:
[codeblock]
func _make_custom_tooltip(for_text):
var tooltip = preload("SomeTooltipScene.tscn").instance()
tooltip.get_node("Label").text = for_text
return tooltip
