I´ve learned how to load an image and set it as my main window background. Now, is it possible to add transparent Ctrls to the main window, so that the background image is visible through the Ctrl panes?
I´m running on Windows.
Thank you!

In some cases yes, but mainly no. Ctrls tend to draw their own backgrounds ('w.DrawRect(GetSize(), SColorPaper)' usually), so whether or not it can be made transparent is up to the Ctrl.
ArrayCtrl has a NoBackground option, and some other controls will not draw their background if IsTransparent is set. You'll just have to look at each one. You will have a problem with things like buttons because they are drawn according to native theming and the background for the edges/rounded corners is baked into the theme image. You will have to modify their Chameleon style to get those to look right I think.
