How to change BITMAPBUTTON_BACKCOLOR via the Command?

I am not sure if I am understanding your question here correctly. You want to change the background color of a button after CreateLayout ran? That is not possible. You can flush layout groups and rebuild them at runtime (with buttons with a new color for example). I showed here once the pattern of a dynamic dialog.

Is it possible to change the background color based on the toggle state?

Thanks for your answers!

It depends on how you define 'possible'. Dialogs in itself are static GUIs, you cannot change any of the settings you have set in CreateLayout after the method ran. It does not matter if it is the spacing of a group, the width of a text field, or the background color of a bitmap toggle button.

What you can do in addition to defining the 2nd icon of the toggle button, is flush a layout group and then rebuild that group with a button which has the color you like. So, you wrap all your buttons in a group, and whenever a button is toggled on or off, you change a color in an array of button colors and then flush the buttons and rebuild them using your array of colors to set the background colors (and you also have to reapply the states then). The posting I linked to in my previous example lines out the details of how to do such dynamic dialog GUIs.

Thank you for reaching out to us. Your thread is still okay, but you are surfing here on the edge of 'too many questions in one topic'. Please note that our Support Procedures require users to ask question(s) on a singular well-defined subject in a thread. This cannot become a 'everything about GeDialog' or 'everything about bitmap buttons' thread.

How to remove padding between buttons?

The padding between elements of a group in a dialog is controlled with GeDialog.GroupSpace.

How to activate fading fading when the back color is activated?

I do not think that is possible, because for that you would have to define a second color to fade to. And I do not see any option to do this in the settings of this custom GUI.

    # not supported by Script Manager scripts.

    main()

This may not help, I'm not a python coder, but for the padding, it might be worth trying to set the BITMAPBUTTON_NOBORDERDRAW flag. I can't tell from the screen shot if that's happening here, but it might be the button border? See if that helps.

I'll let others help you with your other queries.
