// 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%"});

Parameters

width	Width of the widget
height	Height of the widget

Warning: This setSize overload must never be used from internal TGUI code or by custom widget implementations

◆ setText()

virtual void tgui::ButtonBase::setText ( const String & text )

virtual

Changes the caption of the button.

Parameters

text	New text to draw on top of the button

Reimplemented in tgui::BitmapButton.

◆ setTextSize()

void tgui::ButtonBase::setTextSize ( unsigned int size )

overridevirtual

Changes the character size of the text.
