Member Function Documentation

◆ clone()

TGUI_NODISCARD Widget::Ptr tgui::ChildWindow::clone ( ) const

overrideprotectedvirtual

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.

Reimplemented in tgui::ColorPicker, tgui::FileDialog, and tgui::MessageBox.

◆ close()

void tgui::ChildWindow::close ( )

Try to close the window.

This will trigger the onClosing signal. If a callback function for this signal sets the abort parameter to true then the window will remain open. Otherwise the onClose signal is triggered and the window is removed from its parent.

If you want to close the window without those callbacks being triggered then you need to use the destroy() function.

◆ copy()

static TGUI_NODISCARD ChildWindow::Ptr tgui::ChildWindow::copy ( const ChildWindow::ConstPtr & childWindow )

static

Makes a copy of another child window.

Parameters

childWindow The other child window

Returns: The new child window

◆ create()

static TGUI_NODISCARD ChildWindow::Ptr tgui::ChildWindow::create	(	const String &	title = `""`,
		unsigned int	titleButtons = `TitleButton::Close`
	)

static

Creates a new child window widget.

Returns: The new child window

◆ destroy()

void tgui::ChildWindow::destroy ( )

Closes the window.

This function is equivalent to removing the window from its parent. If you want to be receive a callback and have the ability to abort the operation then you should use the close() function instead.

◆ draw()

void tgui::ChildWindow::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.

Reimplemented in tgui::ColorPicker.

◆ getChildWidgetsOffset()

TGUI_NODISCARD Vector2f tgui::ChildWindow::getChildWidgetsOffset ( ) const

overridevirtual

Returns the distance between the position of the container and a widget that would be drawn inside this container on relative position (0,0).

Returns: Offset of the widgets in the container

Reimplemented from tgui::Container.

◆ getClientSize()

TGUI_NODISCARD Vector2f tgui::ChildWindow::getClientSize ( ) const

Returns the client size of the child window.

Returns: Size of the child window contents

This sets the size of the child window excluding the title bar and the borders.

◆ getInnerSize()

TGUI_NODISCARD Vector2f tgui::ChildWindow::getInnerSize ( ) const

overridevirtual

Returns the space available for widgets inside the container.

// Place the widget on an exact position
widget->setPosition({40, 30});
 
// Place the widget relative to the size of its parent
widget->setPosition({"5%", "10%"});
 
// Place the widget 50 pixels below another widget and automatically move it when the other widget moves
