[vlc-devel] [Patch] fix for VolumeBar in Toolbar, compatible to wxwidgets 2.8

[Dominique Leuenberger]

Hi,

As you know, when compiling vlc 0.8.6 and also 0.9.0 against wxwidgets  
2.8, the volume bar and the speaker icon in the toolbar are mis-aligned.

Together with the wxwidgets team we found that there seems to be a  
problem when positioning custom controls in the toolbar. The solution  
was to get rid of the customn control (which was just a combination of  
a bmp tool and a wxGauge) and put the two objects independent in the  
toolbar.

There patch strips out the VLCVolCtrl Class (no longer needed) and  
places a bmp tool and a wxSlider in the Toolbar (I replaced the  
wxGauge; wxSlider is actually more what correct for this use case, and  
in plus, wxGauge does not have any Events, as it's meant as an  
'output' only.

When the slider is moved completely to the left, the speaker bmp is  
changed to speaker_mute_xpm.

The patch is for 0.8.6f, I'll work on a patch for 0.9.0 today.. I  
assume there should not be much differences, considering the fact that  
not much changes were done on wxwidgets for 0.9.0, due to missing  
maintainer.

Maybe this patch could go in a upcoming 0.8.6x version tree (should  
there be any). (I did not yet test the patch against wxwidgets 2.6,  
but considering that there are only standard widgets used, this should  
not be to much of an issue, (praying for it)

Dominique
