Transparent background for SCWindow

[Eirik Blekesaune]

Is there any way to make the background for a window transparent while keeping the image drawn by Pen still visible? I want to have the white background transparent, but keep the blue oval in the middle visible in this code:

(
w = Window.new("circleSelector", Rect(800,300,300,300), border: false);
w.view.background_(Color.new(1.0, 1.0, 1.0, 1.0));

w.drawHook = {
    Pen.addOval(w.view.bounds.insetBy(30));
    Pen.fillRadialGradient(w.view.bounds.center, w.view.bounds.center,
        0, w.bounds.width, Color.blue, Color.cyan);
};

w.front;
)

Hi Eirik,

on OS X only

you can try this SCWindow extension:

+SCWindow {

asNSWindow {

var view, window;

view = SCNSObject.newFromRawPointer(dataptr);

window = view.invoke("window");

view.release;

^window; // you own it - call release once you do not need it anymore

}

}

then try to hack something with the cocoa bridge like that :

(

w = SCWindow.new("circleSelector", Rect(200,400,300,300), border: false);

t = w.asNSWindow;

t.invoke("setOpaque:", [false]);

t.invoke("setBackgroundColor:", [Color.clear]);

w.view.background_(Color.clear);

//w.view.background_(Color.new(1.0, 1.0, 1.0, 1.0));

w.drawHook = {

    SCPen.addOval(w.view.bounds.insetBy(30));

    SCPen.fillRadialGradient(w.view.bounds.center, w.view.bounds.center, 0, w.bounds.width, Color.blue, Color.cyan);

};

w.onClose_({t.release});

w.front;

)

// ...ect...

w.close; // needed

and your window should be now transparent... seems to work (intel Leopard 10.5.6)

i know --- kinda hacky :)

hth anyway

best,

charles

here's the trick for swingOSC, but i think that only works on OS X:

w = JSCWindow.viewPalette;
~comp = JavaObject.basicNew( w.id, w.server ).getWindow__;  
~comp.setBackground( Color.clear ); ~comp.destroy;

ciao, -sciss-

Hi Farah,

you forgot to mention which *city* you are talking about. Oh, the website
says Berlin, so it's probably Berlin.

You also posted your mail in reply to another one, which made it nest inside
another conversation, making it less visible (at least in my mail client's
threaded mail sorting).

Anyhow, have fun :)
