Constructor & Destructor Documentation

◆ MenuButton() [1/3]

Create an empty button.

Remarks
With an empty button, you can Button::add() a widget such as a Pixmap or Box. If you just wish to add a Label, you may want to use the
MenuButton(cuString& label)
ctor directly instead.

Definition at line 51 of file menu-button.cpp.

◆ MenuButton() [2/3]

MenuButton ( StockID const &  stock_id)

Creates a new Button containing the image and text from a stock item.

MenuButton ( cuString &  label,
bool  mnemonic = false 
)
