paint

I'm trying to use the method described here to use a QPainter and GDI calls on the same widget. Unfortunately this tutorial seem to have been written on an earlier version of Qt and now it does not work. I set the WA_PaintOnScreen flag and reimplement paintEngine() to return NULL. Then on the paintEvent() I create a QPainter, use it and then use some GDI calls to paint a bitmap. The GDI calls work fine but the QPainter does nothing. I get the following error on the console: QPainter::begin: Paint device returned engine == 0, type: 1 Is this simply not supported anymore? how can I do it? I've

I have some code that creates a full screen icon in java and sets the background color to pink and the foreground color to red. However every time i run it, it never changes the background color to red but just keeps it see through. I put the code below. The main java: import java.awt.*; import javax.swing.*; @SuppressWarnings({ "serial" }) public class bob extends JFrame{ public static void main(String[] args) { DisplayMode dm = new DisplayMode(800,600,16, DisplayMode.REFRESH_RATE_UNKNOWN); bob b = new bob(); b.run(dm); } public void run(DisplayMode dm){ setBackground(Color.PINK);

This is similar to my own previous question , but that solution didn't work here. As mentioned in the previous question, I'm working on a cross platform(Windows/Ubuntu) application that has to transliterate English into one of several official Indian languages. The application has a custom input method, and typing in English and pressing space will transliterate the typed text into the specific local language. Urdu is different from the others in being right to left, like Arabic/Hebrew. I managed to find an open licensed Urdu font that has both English and Urdu glyphs, but when I type

I've got a Problem: In my Java application I've got an AWT Component (cannot change that one) that streams and shows an avi-file. Now I want to draw upon this movie and thought about putting a transparent JPanel above it and draw on that one. This does not work since I either see the avi-stream or the drawn lines but not both. I read somewhere that AWT does not support transparency of components - but the panel is a JPanel which is able to do so. Can someone please help me with this one - thanks in advance. The Mixing Light and Heavyweight Components article explains how this is handled only

I asked this before, but only theoretically, without an SSCCE. Now, I've created one, and the problem persists. I'd like to know why paintComponent is not called on repaint(x, y, w, h) , but is called on repaint() . Two classes: SANDBOX import java.awt.Dimension; import java.awt.FlowLayout; import javax.swing.JFrame; public class Sandbox { public static void main(String[] args) { JFrame f = new JFrame(); f.setMinimumSize(new Dimension(800, 600)); f.setLocationRelativeTo(null); f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); f.setLayout(new FlowLayout()); // Add label f.getContentPane().add
