Status: RESOLVED DUPLICATE of bug 58048

(Core :: Layout: Form Controls, defect)

Description

[Tom Brunet]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.3) Gecko/20070309 (CK-IBM) Firefox/2.0.0.3
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.3) Gecko/20070309 (CK-IBM) Firefox/2.0.0.3

When page colors are overriden, the rendering engine applies foreground and background color to the disabled control, and throws out color blending done to indicate disabled controls.

Reproducible: Always

Steps to Reproduce:
1. Override page colors (Tools->Options->Content->Color).  Check "Use System Colors" and uncheck "Allow pages to choose their own colors".
2. Load the attached "disabled.html" or load any page that has disabled form controls.

Actual Results:  
The left set of controls in the "disabled.html" are active controls and the right set are disabled controls.  Notice that the radio button and checkbox maintain their disabled colorings, however the button and text box are difficult or impossible to identify which is the disabled form control.

Is it a problem for XUL as well?

Comment 3

[Tom Brunet]

No, Aaron.  It appears not to affect the XUL equivalent controls.  I'll attach an XUL equivalent to the HTML version.

Attachment: XUL version of the HTML controls in the previous attachment.

This is an XUL version of the HTML controls in attachment 262766 [details].
