How to customize style of TMainMenu and TPopupMenu?
« on: November 24, 2024, 02:17:51 pm »
I want to customize styles of TMainMenu and TPopupMenu, eg: changing menu item color.

But it seems TMainMenu and TPopupMenu are OS-dependent. I used OwnerDraw with customized OnDrawItem and OnDrawItem but it works only on Windows.

I want to customize menu styles which support cross-platform: Windows, macOS (Cocoa) and Linux (QT, GTK). Is it possible to do that?

Thank you so much,  :)

You can easily write your own popup menu. For example this is my popup with listbox in the User Interface section in the link below:

For TMainMenu, I still have no idea.

Maybe make MainMenu something like this?
Tested on both Windows 11 and Linux(gtk2). Please take a look at the attached project.

Nice!

But things will become complicated if we need sub menus.

It seems does not have any easy way to custom menu. Thank you so much :)

One more question. Is there any solution (built-in component, external libraries...) to custom draw menu?  :)

A quick search revealed this thread and it seem to be manual labour.

It seems OwnerDraw and OnDrawItem work only on Windows. I tested with Linux GTK and QT but OnDrawItem() has no effect.

I think have to use self-draw control or using another control to simulate popup menu.
