wx.ALPHA_TRANSPARENT

wxPython Users

Hi,

As I am positionning widgets on a backgroud bitmap, I am attempting to have
these widgets transparent.

I use wx.ALPHA_TRANSPARENT as 4 parameter of wx.Colour which I then try to
apply to a wx.ListCtrl ... and I get a black control instead.

Is there a way to get that done ?

PS: same behavior under Windows & Linux

Regards,

Philippe

So far the alpha component of wx.Colour is only used for drawing with a graphics context. The widgets themselves don't even look at it.

Not really, not with the native widgets anyway. On windows all of the widgets are an actual window, meaning that they have a background, etc. There isn't a good way to make them appear transparent without going to a lot of effort. On the other platforms some widgets (like wx.StaticText) are actually either drawn directly on their parent window or are truly transparent, so they behave a little more like what is usually expected in those cases.
