 N/A N/A Yes N/A

scaleIcon

Defines the scaling behaviors of the associated icon, if the source image size is bigger than the place reserved for it in the widget.

Note: On GDC and GWC, if the scaleIcon attribute is undefined, the behavior depends on the kind of action view: toolbar button icons and action panel button icons are scaled down to match the size of the widget. For other widgets, by default no scaling occurs, as for scaleIcon="no".
Values can be:
  • "no": No scaling occurs and the image is taken as-is. It is up to the developer to resize the source image to avoid misalignment. This is the default on GDC/GWC.
  • "yes": Image are scaled down according to the height of the widget (button or edit field). Setting a big font can result in a big icon. This is the default on GMA/GMI.
  • "nnnpx": Image are scaled down according to the specified size. For example, scaleIcon="128px" will make every icon a maximum of 128*128 pixels. At least one side equal to 128 pixels, depending if the source image is square or not.

Independently of the style value, the source image is never upscaled to avoid pixelization or blurring of the image. The exception is when the image come from an SVG file which can be upscaled without any penalty. If the icon must be enlarged, the image is centered and a transparent border is added to "fill" the empty space. This allows a mix of larger and smaller icons while keeping widget alignment.

If scaling takes place, the aspect ratio of the original image is kept. A non-square source image displays as a non-square scaled icon.
