◆ draw()

void tgui::RootContainer::draw ( BackendRenderTargetBase target,
RenderStates  states 
) const
overridevirtual

Draws all widgets to a render target.

Parameters
targetRender target to draw to
statesCurrent render states

Reimplemented from tgui::Container.

◆ isMouseOnWidget()

bool tgui::RootContainer::isMouseOnWidget ( Vector2f  pos) const
overridevirtual

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

Returns
Is the mouse on top of the widget?

This function always returns true.

Implements tgui::Widget.

◆ setFocused()

void tgui::RootContainer::setFocused ( bool  focused)
overridevirtual

Focus or unfocus the widget.

Parameters
focusedIs the widget focused?

The gui container can't be unfocused.

Reimplemented from tgui::Container.

◆ setSize() [1/3]

virtual void tgui::Widget::setSize

Changes the size of the widget.

Parameters
sizeSize of the widget

Usage examples:

// Give the widget an exact size
widget->setSize({40, 30});
// Give the widget a size relative to the size of its parent
widget->setSize({"20%", "5%"});
// Make the widget 50 pixels higher than some other widget and automatically resize it when the other widget resizes
widget->setSize({200, tgui::bindHeight(otherWidget) + 50});

◆ setSize() [2/3]

void tgui::RootContainer::setSize ( const Layout2d size)
overridevirtual

Changes the size of the container.

Parameters
sizeThe new size of the container
Warning
This function should only be called by the Gui as the size should match with the view used by the Gui

Reimplemented from tgui::Container.

◆ setSize() [3/3]

void tgui::Widget::setSize
inline

Changes the size of the widget.

Parameters
widthWidth of the widget
heightHeight of the widget
Warning
This setSize overload must never be used from internal TGUI code or by custom widget implementations

The documentation for this class was generated from the following file:
TGUI_API Layout bindHeight(GuiBase &gui)
Bind to the height of the gui view.
