I’m using the IconComponent as the background for a Button. The base image size used in the IconComponent is larger than the desired button size, when the IconComponent is set as the background, the image does not appear to scale down to fit within the button size. I have HAlign and VAlign set to bottom left and overlay is set false.
Am I missing something or do I have to set the scale of the IconComponent manually in this case?
Actually, looking at the code again, IconComponent is designed purposely to keep the icon a specific size because it’s part of how the button is sized. It’s actually tricky for it to decide if it should stretch or just factor into the button’s size.
Call setIconScale() to set it to the size that you desire. I see that you have the commented out, though.
I just hit this issue. Pretty standard setup, so I don’t think there’ll be any surprises, but here’s my use-case. I’m designing an icon set. All buttons share a common background (a 64x64 bullseye texture) image. Specific icons are made to be centered on top of this background - for example, there’s a checkmark icon for “accept” buttons, and these icons are saved as 64x64 PNGs without the background. This way, background changes don’t require reworking the entire icon set, and there’s greater flexibility at runtime for things like re-coloring and other goofiness. I’d like to just create a text-less button, set the background to the bullseye texture and the icon to whatever it’s supposed to be and then re-scale the entire shooting match to take up, say, 30x30 pixels on screen without having to separately scale the button/background at the icon. It’s not hard to get the same effect, but it adds extra clutter to my style file that would be nice to avoid.
The proposed add-on in this thread would be something like a setIconSize() that essentially does the same thing as setIconScale() except it would determine the scale based on the current icon’s size. So if you setIconSize(64, 64) and then give it an icon that is 32, 32 it would internally scale by 2.
Would that help you?
It seems like maybe you are asking for something different since it’s a relatively small change to calling code to do one or the other when the IconComponent is created.
Yes, that’s exactly what I’m trying to describe. In my particular case (for this particular button) I’m trying to scale down, not up, but it’s the same situation - it would be really handy to express icon scale in terms of pixels rather than in terms of ratios of the original size.
