Title basically says it all but I'll elaborate. With increasing monitor resolution, a 16x16 glyph on a listbox doesn't work very well. On a 4K monitor this is awful tiny. This idea is to support larger glyphs in Listboxes, Multi-column Listboxes, and Trees. Glyphs are used in several places but on favorite of mine is to have item selection with checkboxes,example here. Allowing for these glyphs to grow with the row height would make them appear more cohesive. There is a threaddiscussing this topic, and a work around involving an array of picture rings that is placed over the listbox control. Here is a demo from that thread:
This work around is fine for simple things but doesn't scale well, and doesn't support trees easily. I for instance want to have two trees, where a user can drag and drop from one to the other with the larger glyphs coming along with the drop. Having to handle where the user dropped, and then dynamically building the glyphs to overlay on top of the tree, with indentation, and hiding when a tree's leaf is closedis a major pain. Please NI add a feature allowing for larger glyphs, and I would be so happy.
