When the TAdvOfficeFontSelector width property is greater than 345, the dropdown width is very narrow. For widths 345 or less, the dropdown is wide and I would say it is about 345 in width because if I make the control 345 in width, the dropdown is about the same width.
BTW, I can set the DropDownWidth to the control's width on the panel resize which fixes my issue, but if I leave the DropDownWith set to 0, then this issue shows up. So no biggy, more of an unexpected behavior of the control.
When DropDownWidth = 0, the width of the dropdown should autosize to the max. needed width for the fonts displayed in the dropdown. This is what I see here.
When DropDownWidth is configured to another value, I see that this width is used here, regardless of the control with or dropdown content size.
This was tested here with a default TAdvOfficeFontSelector on the form and I could not see an unexpected behavior in this regard.
I agree that that should be the expected behavior, but unfortunately it is not what I experienced. Not sure why, maybe an interaction with something else on the frame. I'd send you an example but decided on a different control. If I go back to it and still have issues, I'll send you something. Thanks for looking into it though!
