Most likely we should not mess with spacing at all. Rather we should use the default wxWidget spacing for everything. The reason for this is that the spacing is different on all platforms, and changes even on a specific platform if translations are used. The wxDefault... is designed to handle everything, so use that. Yes, sometimes this is not the prettiest at times, but that is the proper way to do this.

Oh, wait you are just talking about above/below the dialog ok/cancel buttons. That is okay to configure.

You might probably want to look into http://docs.wxwidgets.org/2.8/wx_wxstddialogbuttonsizer.html#wxstddialogbuttonsizer ;)

Seems to work pretty nicely, working on it ;)

NeoBrainX: Many of the dialogs are already using that. I recently switched many of them to use wxDialog::CreateButtonSizer which uses the wxStdDialogButtonSizer internally.

oh, didn't know that we were already using that.
At least the video config dialog doesn't use it, yet. So this issue just boils down to finding the remaining dialogs which don't use wxStdDialogSizer, yet :P
