第一次繪製時,繪製不正確。 但是,當我最小化框架並恢復它時,它被正確繪製。重新繪製Aero JFrame
我該如何解決這個問題?我試圖重繪()。
下面是代碼
import javax.swing.JComponent;
import javax.swing.JFrame;
import com.sun.jna.Function;
import com.sun.jna.Native;
import com.sun.jna.NativeLibrary;
import com.sun.jna.Structure;
import com.sun.jna.platform.win32.WinDef.HWND;
import com.sun.jna.platform.win32.WinNT.HRESULT;
/**
* @author ex0b1t
*
*/
public class Aero {
public void enableAeroEffect(JFrame frame) {
NativeLibrary dwmapi = NativeLibrary.getInstance("dwmapi");
HWND aeroFrameHWND = new HWND(Native.getWindowPointer(frame));
MARGINS margins = new MARGINS();
margins.cxLeftWidth = -1;
margins.cxRightWidth = -1;
margins.cyBottomHeight = -1;
margins.cyTopHeight = -1;
Function extendFrameIntoClientArea = dwmapi
.getFunction("DwmExtendFrameIntoClientArea");
HRESULT result = (HRESULT) extendFrameIntoClientArea.invoke(
HRESULT.class, new Object[] { aeroFrameHWND, margins });
if (result.intValue() != 0)
System.err.println("Call to DwmExtendFrameIntoClientArea failed.");
frame.getRootPane().setDoubleBuffered(false);
frame.getRootPane().setOpaque(false);
if (frame.getRootPane().getContentPane() instanceof JComponent) {
JComponent content = (JComponent) frame.getRootPane().getContentPane();
content.setOpaque(false);
content.setDoubleBuffered(false);
}
}
/**
* @author ex0b1t
*
*/
public class MARGINS extends Structure implements Structure.ByReference {
public int cxLeftWidth;
public int cxRightWidth;
public int cyTopHeight;
public int cyBottomHeight;
}
}
import javax.swing.JFrame;
/**

*/
public class MediaManager extends JFrame {
private static final long serialVersionUID = -8440221168382362270L;
public MediaManager() {
setTitle("Media Manager");
setSize(800, 600);
setDefaultCloseOperation(EXIT_ON_CLOSE);
}
/**
* @param args
*/
public static void main(String[]args){
MediaManager mediamanager = new MediaManager();
mediamanager.setVisible(true);
new Aero().enableAeroEffect(mediamanager);
mediamanager.repaint();
}
}
預先感謝。
