Bug 27814 – Qt Port does not obey color style in button tag with default background

• Status: RESOLVED
• Resolution: FIXED
• Component: New Bugs

[Mike Fenton]

In the Qt Port, anytime the theme paints a button object, the buttons style color property is ignored.

Ie.

<button style="color:red">  Does not draw a button with red text.
<button style="color:red;background-color:blue> Does draw a button with red text and blue background.

This is happening because in adjustButtonStyle of RenderThemeQt, in addition to setting expected values, there is the following line

style->setColor(QApplication::palette().text().color());

which resets the theme color to the default text color.

By removing this line the Qt Port correctly draws the text color including effects for the button.

Note:  This was discovered while investigating the failure of fast/dom/HTMLTableColElement/resize-table-using-col-width.html which was failing due to a color mismatch in the expected vs actual results.

With no style provided default values were expected but the follow response occurs.

-        RenderButton {BUTTON} at (2,2) size 393x28 [color=#1A1A1A] [bgcolor=#C0C0C0]
+        RenderButton {BUTTON} at (2,2) size 393x28 [color=#141312] [bgcolor=#C0C0C0]

With the fix the output is

         RenderButton {BUTTON} at (2,2) size 393x28 [bgcolor=#C0C0C0]

denoting that the color was not overridden.

Next time you can combine these two.  A bug fix and the associated tests should land together.  I'll do so when landing.
