Member Function Documentation

◆ clone()

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

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.

static

Makes a copy of another child window.

Parameters
childWindowThe other child window
Returns
The new child window

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.
