i'm using transparent (shaped) jframe under java 6 mac os x.
my system tells me translucency.perpixel_translucent supported. although system tells me translucency.perpixel_transparent not supported, found out works under mac os x when putting pixels alpha=0.
now, when selecting text in jtextfield, drags window if drag on underlying contentpane.
here sample code try (contains main-method run on computer)
import com.sun.awt.awtutilities; import java.awt.color; import java.awt.gradientpaint; import java.awt.graphics; import java.awt.graphics2d; import java.awt.paint; import java.awt.shape; import java.awt.geom.ellipse2d; import javax.swing.jbutton; import javax.swing.jframe; import javax.swing.jpanel; import javax.swing.jtextfield; import javax.swing.swingutilities; public class dialogtest extends jframe { public dialogtest() { setbackground(new color(0, 0, 0, 0)); jpanel p1 = new jpanel() { public void paintcomponent(graphics g1) { if (g1 instanceof graphics2d) { paint p = new gradientpaint(0.0f, 0.0f, new color(240,240,240, 0), 0.0f, getheight(), new color(240,240,240, 255), true); graphics2d g2d = (graphics2d) g1; g2d.setpaint(p); shape s = new ellipse2d.double(0,0,getwidth(),getheight()); g2d.fill(s); } } }; add(p1); p1.setopaque(false); p1.add(new jbutton("button 1")); jtextfield tf = new jtextfield("sample text select"); p1.add(tf); p1.add(new jbutton("button 2")); setundecorated(true); setsize(400,400); awtutilities.setwindowopaque(this, false); } public static void main(string[] s) { // create gui on event-dispatching thread swingutilities.invokelater(new runnable() { @override public void run() { dialogtest tw = new dialogtest(); // display window. tw.setvisible(true); } }); } }
