[Solved!!!] Getting basic state-dependent properties for a component

[heebiejeebies]

Thanks everyone for the suggestions!  I already had the workaround which was showing the PopupMenu when clicking a button, but to me (At least for my purposes) it looks clunky and non-standard.  Lucamar nailed it - I need a TCombobox with style set to csDropdownlist.  That works perfectly for me - I can't edit it at all?  Hope it is the same for my users.     I'll try it anyway and see how it goes.  Thanks everyone!

Just testet with Laz 2.0.10 on LinuxMint 19.2 Cinnamon 64bit, works as expected there.

You're right. I re-tested and it works as it should. I must heve done something wrong the first time ... like forgetting to set the correct Style

Hope it is the same for my users.

It should; to pay for my carelessnes I tested both Windows (32 bit) and Linux (32/64 bits) and it worked correctly everywhere. Sorry about the previous "noise"

No problems at all, thanks heaps for finding the right component - I'd never have found it!

Btw just for any future Googlers, in answer to the initial question, it seems that, yes, typing the component name followed by a dot in the script editor does bring up all the relevant properties and procedures that can be applied to that component.  In this case, the original property that I was looking for was simply the Caption.  With a TComboBox, whatever the user selects becomes the caption. Easy

Rather than Caption, for a combo box I'd recommend you read the Text property. Though both will, probably, return the same.
