Detailed Description

Widget that is added to a container when the user clicks on the menu bar. This widget will be added in front of all other widgets to ensure that the menus from the menu bar are always drawn in front of other widgets.

Constructor & Destructor Documentation

◆ MenuBarMenuPlaceholder()

tgui::MenuBarMenuPlaceholder::MenuBarMenuPlaceholder ( MenuBar * menuBar )

Constructor.

Parameters

menuBar The menu bar that owns this menu

Member Function Documentation

◆ clone()

Widget::Ptr tgui::MenuBarMenuPlaceholder::clone ( ) const

nodiscardoverridevirtual

Makes a copy of the widget if you don't know its exact type.

This function should only be used when you don't know the type of the widget. If you know what kind of widget you are copying, you should use the copy function.

Returns: Copy of the widget

Implements tgui::Widget.

◆ draw()

void tgui::MenuBarMenuPlaceholder::draw	(	BackendRenderTarget &	target,
		RenderStates	states ) const

overridevirtual

Draw the widget to a render target.

Parameters

target	Render target to draw to
states	Current render states

Implements tgui::Widget.

◆ getFullSize()

Vector2f tgui::MenuBarMenuPlaceholder::getFullSize ( ) const

nodiscardoverridevirtual

Returns the entire size that the widget is using.

Returns: Full size of the widget

This MenuBarMenuPlaceholder widget will try to fit the entire screen to absorb all mouse events.

Reimplemented from tgui::Widget.

◆ getWidgetOffset()

Vector2f tgui::MenuBarMenuPlaceholder::getWidgetOffset ( ) const

nodiscardoverridevirtual

Returns the distance between the position where the widget is drawn and where the widget is placed.

Returns: Offset of the widget

The offset equals -getPosition() for MenuBarMenuPlaceholder because it tries to fill the entire screen.

Reimplemented from tgui::Widget.

◆ isMouseOnWidget()

bool tgui::MenuBarMenuPlaceholder::isMouseOnWidget ( Vector2f pos ) const

nodiscardoverridevirtual

Returns whether the mouse position (which is relative to the parent widget) lies on top of an open menu.

Returns: Is the mouse on top of an open menu from the menu bar?

Implements tgui::Widget.

◆ leftMouseButtonNoLongerDown()

void tgui::MenuBarMenuPlaceholder::leftMouseButtonNoLongerDown ( )

overridevirtual

Reimplemented from tgui::Widget.

◆ mouseMoved()

void tgui::MenuBarMenuPlaceholder::mouseMoved ( Vector2f pos )

overridevirtual

Reimplemented from tgui::Widget.
