Panel Buttons

Properties

• A panel button can be pressed by clicking a mouse button when the mouse pointer is inside its area.
• Each button has a label, a bitmap or a pixrect (displayed on the button) and an associated number.
• Buttons can have associated action functions of type

    void (*action) (int but)

  or an attached subwindow. In the latter case, we call the button a menu buttons.

Creating a Menu Bar

There are two styles for menu buttons, i.e., buttons with an attached subwindow.

In the default style, menu buttons are displayed as buttons with an additional menu-sign.

In the second style, menu buttons are arranged into a menu bar at the top of the panel section. The function

	void W.make_menu_bar()

selects the menu button style.

The Example Menu Bar demonstrates both alternatives for menu buttons.
