a11y: ComboBox menu selection should match native SELECT

[Douglas Hays]

Tested on Firefox 3.0.7 on WinXP.

Enable high-contrast. Run test_ComboBox.html. Click the combobox arrow and down arrow a few times. Each item in the list has a small dotted outline as you down arrow, but when using a native SELECT element, the background is purple giving a much greater contrast. I think this is achieved by do a "selection" of the text. I think we should do this in addition to, or as a replacement for, changing CSS classes for each menu item.

Isn't this impossible? High contrast mode doesn't let you pick colors for the text/background. (There's only one color for text, typically white, and one color for the background, typically black.)

[Douglas Hays]

I'm not picking a color. I'm suggesting to select the text (like you're going to copy and paste it) and that signals the browser to do its native thing - like reverse-video or purple background in the case of Firefox 3.

Moving to future as I do not know of a way (nor can I find one) to programmatically select text that is NOT in an input text box or textarea.

[bill]

Should be doable through dijit._editor.selection.selectElementChildren(). (Of course that code should be refactored to somewhere common, like dijit/ or dijit/_base.)

reassign due to inactive committer. please triage accordingly.

A pull request would be welcome for this if it is still an issue, but given the lack of activity over the past 5+ years, I'm closing this one.
