V12 Beta - view.caret_line_layer = view.LAYER_UNDER_TEXT seems to overrides view.ELEMENT_SELECTION_BACK

[merlindiavova]

Hi,

When I set view.caret_line_layer = view.LAYER_UNDER_TEXT in my theme, it seems to override the view.ELEMENT_SELECTION_BACK with view.ELEMENT_CARET_LINE_BACK for the current line only.

I can highlight all other lines however the line that has the caret and a selection just shows the view.ELEMENT_CARET_LINE_BACK color not view.ELEMENT_SELECTION_BACK.

Any ideas?

Please see my theme below

local view, colors, styles = view, view.colors, view.styles

Your view.element_color[view.ELEMENT_CARET_LINE_BACK] is not a translucent color. I think Scintilla (Textadept's editing component) draws selections first and then the caret line, so with an opaque caret line, it's overwriting the selection background.

I was able to see the selection background using this:

  view.element_color[view.ELEMENT_CARET_LINE_BACK] = colors.bg_line | 0x60000000

Tweak the alpha byte to something that suits you.
