Demo - A Custom Menubar Element Simulated Using ButtonMenu Elements
|
||||
Demo - The MenubarCustom element
|
||||
|
||||
With the addition of the Custom Titlebar came the addition of a problem with the
|
||||
os provided menubar. It's not possible to use the custom titlebar with the
|
||||
normal menubar. The menubar ends up being placed above the titlebar.
|
||||
|
||||
Enter the MenubarCustom!
|
||||
|
||||
This "Compound Element" is not really an element but rather a combination of
|
||||
ButtonMenu elements and Column elements. It's possible for users to create a similar
|
||||
construct. In fact, this element started as a Demo Program and then migrated into PySimpleGUI.
|
||||
|
||||
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.
|
||||
At the moment, you cannot perform all of the same operations using this custom menubar
|
||||
that you can with a traditional menubar. Modifying the menu isn't possible yet. In
|
||||
other words, it's a great start, but more work is needed such as adding an update method, etc.
|
||||
|
||||
For statically defined menus, it works great. Shortuts are possible within the menus, but not
|
||||
for the initial selection.
|
||||
|
||||
You can use the same menu defition as the standard Menu element.
|
||||
|
||||
The Menubar will tbe themed according to your current theme's colors. The theme's button
|
||||
colors are used. All of the colors can be changed from the menubar to the menu's text an background.
|
||||
|
||||
The disabled color has a problem. The default tkinter gray is used even though PySimpleGUI sets the value.
|
||||
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.
