RollDown Palette

RobDev — Thu, 15 May 2025 11:45:24 GMT

Hi all,

I'm looking to create a RollDown dialog similar to the BasicElementIconsRollDownDialog from DG_Test, but as a palette. I found this forum thread with pretty much the same question, but the accepted answer hasn't really helped me much. |'ve tried to implement a rolldown palette inheriting the correct base class using a similar method to how I'd implement a normal palette but haven't had any success. Would anyone be able to point me in the right direction as to how to create a functioning rolldown palette? An example would be very much appreciated.

Thanks,

Rob

Hi!

It seems like the post above was something I asked about earlier. But sadly, after 4 years, I still haven’t been able to implement the roll-down palette. Now I’m trying to work on it again, hoping someone might be able to provide a concrete example.

Can you to implement not roll-down palette ?

In my opinion, there are two tasks. How to create a palette and how to create a roll-down dialog (including a palette).
Implementing ang handling any palette is not so simple, roll-down or not.

About a palette dialog see the DG_Test example, OwnerDrawnListBoxPalette class.
Pay attention to: ACAPI_RegisterModelessWindow in Initialize function, ACAPI_UnregisterModelessWindow in FreeData function, OwnerDrawnListBoxPalette::PaletteAPIControlCallBack, BeginEventProcessing() in constructor, the class implemented as a singleton, need to call Show method to make visible created palette.
