Adding a multi-select button in a custom module

HFCDev

Hi, 

  I've been tasked with creating a new multi-select button for my client. They want the ability to add multiple items to their favourites.  Doing the action is not so hard, but I'm having a bit of trouble understanding what is going on with the Button object in terms of its rendering.  The button object (orphaned from Webnode.MultiSelectModule) has an fOrder field which gives where it should appear in the list, although I've found that setting that number to something that already exists will not work.  But what is confusing me is the fImageXpos[2] and fImageYPos[2] values.  They appear to be set to absolute values, with the core assumtion that assumptions are being made about which other buttons are in the system, which is not a valid assumption as you may or may not have the RM or PO module installed.

   Is there any documentation on the *correct* way to set up a new multi button? I can get mine to render, but because I set those X/Y pos to undefined, it's using the image I specify for my fImage property as both the foreground and background image with strange results.

Thanks in advance

This is my second time trying to post this. I have it figured out.

The thing that was messing me up was the meaning of those .fImageXPos/,fImageYPos.  They are positions on an image map defined in .fImageMap which typically lists out all the buttons imagery on a single png.  It appears that the old-school is to just define .fImage and .fImage2 to define background images.  The main advantage of the new approach is that it allows you to specify buttons that are stretched out, and it makes for a quicker edit. I did notice that if you use the .fImage/2 features, the image doesn't change when you hilight it but only when you click it.

Beware the .fOrder though. If there are two multi-action buttons with the same .fOrder, the older one will clobber the newer, and your button won't show up.

Nice to have feature request: How about an object factory for Multi-buttons so they can be set on the privileges page?
