[Qt-interest] QWebView inactive highlighted text color background

[Strahinja Markovic]

Hi,

I was wondering what would be the best way to change the background color of 
the selected text highlight in QWebView when the window is inactive?

Let me elaborate...

I'm using a (sub-classed) QWebView as a WYSIWYG editor component, and I've 
now mostly implemented a find&replace dialog. Now the dialog is a separate, 
non-modal window that can control the QWebView. I have managed to 
successfully select the searched-for text with JavaScript, but since the 
QWebView is in a separate window which is inactive, the text is highlighted
in a very light gray color. It's barely distinguishable from the white 
background.

Now if I switch the focus back to the main window, the highlight is that 
nice blue color again. But I don't want the main window to have focus. I 
want the find&replace dialog to keep it so the user can continue pressing 
<Enter> with the "Find Next" button selected.

So I'm wondering how I could change that inactive selected text background 
color. I've already tried using a custom QPalette, but QWebView ignores 
this. I've read this can happen.

I was thinking of getting the size of the dimensions of the highlighted 
rectangle and painting over that, but I don't know how to get those 
dimensions. It also seems like overkill, but I'd be willing to try it.

I know I could do this by temporarily changing the underlying HTML and 
inserting some highlighting CSS + <span>, but that's the last thing I'm 
willing to try. I _really_ don't want to mess with the user's code.

Does anyone have any ideas?

Thanks in advance,
