I believe it should be possible to make my own custom buttons in MUI, but the documentation seems rather lacking on this subject.

I want a button which contains an ImageObject & a Label. Of course I can group them together... but how do I turn it into a button? I guess I need to add some kind of "button frame" & "button background", and somehow imbue it with clickable behaviour, but I haven't a clue where to start. The SimpleButton() macro doesn't expand to anything that would help me here.

Help!

Made some progress: The CheckMark() macro gave me a few hints, and the MUI_Area doc had most of the answers... horribly spread through-out it. Seems like the following should work (but gives rather ugly buttons & currently doesn't show any image for some reason) :


Child, buttonObject := GroupObject,

    MUIA_Background,MUII_ButtonBack, MUIA_Frame,MUIV_Frame_Button, MUIA_InputMode,MUIV_InputMode_RelVerify,

    MUIA_Group_Columns,2,

    Child, ImageObject, MUIA_Image_Spec,"5:tbimages:quit", End,

    Child, Label2(label),

End

edit: OK, I am stumped why the image isn't being shown :(

MUIA_Pressed,MUIV_InputMode_RelVerify

This is wrong. You should not set it and value you set is wrong.

No idea why it is not showing an image but I am always usint Dtpic.mui class.

You can also turn it into custom class. This allows better control (i.e. tinting selected image state).

Quite a regular

I know nothing about MUI, but as a casual observer what is the 5 colon in front of the AISS path and filename for?

"5:" tells MUI it should load an image using datatypes, rather than using some other kind of source for the image.

@porthan
You are right. I've removed that from my code (and my first post)... but it didn't help my problems (unsurprisingly).

@all
I eventually came to the conclusion that ImageObject is simply buggy/broken, and does not work with images loaded via datatypes. Instead I got it mostly working using the Dtpic class:


Child, buttonObject := GroupObject,

    MUIA_Background,MUII_ButtonBack, MUIA_Frame,MUIV_Frame_Button, MUIA_InputMode,MUIV_InputMode_RelVerify,

    Child, GroupObject, MUIA_Group_Horiz,MUI_TRUE,

        MUIA_Frame,MUIV_Frame_None,

        Child, DtpicObject, MUIA_Dtpic_Name, "tbimages:quit", End,

        Child, FreeLabel(label),

        Child, RectangleObject, MUIA_InnerLeft,0, MUIA_InnerRight,0, MUIA_InnerTop,0, MUIA_InnerBottom,0, End,

    End,

End

For some stupid reason the button frame is inherited by everything inside it, and the only way to stop that is to have a second group (!) which explicitly has no frame. Seems crazy, but I couldn't find another way to do it.

It still doesn't look 100% perfect (kinda looks like I have a double frame) but just about good enough.

Oh yeah, and MUI's Dtpic documentation seems to be literally non-existant. The only way to work out how to use it was by a few snippets of code on the web. MUI 3.8 doesn't even include everything needed to use it in the includes, as I had to declare MUIA_Dtpic_Name = 0x80423d72 (and for consistency I also declared DtpicObject using MUIC_Dtpic).

Edit: I was able to duplicate Dtpic's functionality using BitmapObject, but all the extra code doesn't seem to offer any benefit, so I might as well stick with Dtpic.
