When sized too narrow, the dropdown widget currently draws the selected option text over the arrow symbol. At the same time, the widget doesn’t appear to be working with
LV_SIZE_CONTENT set for the width (it just collapses down to almost zero width).
It’d be great if there was a way to automatically make the widget wide enough so that the longest available option fits without drawing over the arrow symbol. In fact, I think this should be the default mode because it looks rather bad when the text overflows into the symbol.
If I understand correctly, the culprit is that the handler for
LV_EVENT_GET_SELF_SIZE only sets the height but not the width. To set the ideal width, I believe we’d have to measure the width of each option, pick the largest and add the width of the symbol.
I’d be curious if such a contribution would be acceptable or if maybe there’s another way to enable auto-width-sizing for the dropdown widget.
