Display quality overlay on a sprite and sprite-button

[hgschmie]

For a sprite button, I can have it overlay a number (for count), by adding a "number = 100" to the LuaGuiElement.

However, with Space Age, there are icons like this (this is the signal display from a combinator):

How do I get the quality overlay for a sprite (or a sprite button)? There is a workaround using a "choose-elem-button" which allows using "item-with-quality" and then in turn use that to display an item with the quality overlay but that can not display a number.

Is there a way to draw a sprite-button that looks like the button in the constant combinator? If not, is it possible to add some additional attributes to sprite-button (and probably also sprite) that allows for the quality overlay?

At this point, I can get the hovers over the icons to work (by using the elem_tooltip attribute):

Code: Select all

button.elem_tooltip = {
  type = 'item-with-quality',
  name = signal_name,
  quality = signal.signal.quality,
}

However, the icons still do not show the quality information:

In the filter selector at the botttom, the icons have a quality marker (this is a table of choose-elem-buttons which display the quality). In the top, the elements (sprite-button) are all plain, even though the tooltips show the quality correctly (see the hover).

The question is still on how to get the quality marker on the sprite buttons.
