Demo - A Custom Menubar Element Simulated Using ButtonMenu Elements
|
|
|
|
Because a Menubar is created by the OS and not the underlying GUI framework, the
|
|
ability to customize the look and feel of the standard Menubar is not possible.
|
|
|
|
Additionally, the Titlebar Element and the Meny Element don't work well together.
|
|
The order gets swapped.
|
|
|
|
One way to get around all of the problems above is to simulate a Menu Element.
|
|
That's exactly what this demo does.
|
|
|
|
The color choice for the menubar background and text use the theme's button colors.
|
|
You can change these color choices by changing the Menubar in the layout.
