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
menuBarThe menu bar that owns this menu

Member Function Documentation

◆ clone()

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

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 ( BackendRenderTargetBase target,
RenderStates  states 
) const
overridevirtual

Draw the widget to a render target.

Parameters
targetRender target to draw to
statesCurrent render states

Implements tgui::Widget.

◆ getFullSize()

Vector2f tgui::MenuBarMenuPlaceholder::getFullSize ( ) const
overridevirtual

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
overridevirtual

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
overridevirtual

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.
