POHow to get rid of ugly SWT button fringes in Windows 7?
text
Body
copied!<p>I maintain a <strong>SWT/JFace</strong> application that has to run in <strong>Windows XP</strong> as well as <strong>Windows 7</strong>. The application has a <code>TabFolder</code> that contains a <code>Composite</code>, that in turn contains the widgets. Nothing unusual and everything works well except for...</p> <hr> <h2>The Buttons</h2> <p>While they look OK in Windows XP they have an ugly grey border in Windows 7.</p> <p><img src="https://i.stack.imgur.com/IRX5T.png" alt="enter image description here"> <img src="https://i.stack.imgur.com/PGPXd.png" alt="enter image description here"></p> <hr> <p><img src="https://i.stack.imgur.com/gY0Ho.png" alt="enter image description here"></p> <p>I could set the background of the button manually but I failed to figure out a way to find out the parents actual background color. <code>getBackground()</code> returns always 240, 240, 240 even if the background is actually white.</p> <p>I found out that in Windows XP the background of a TabFolder is the theme color <strong>3D Objects</strong> while in Windows 7 there is not such correspondence. I tried to set every single theme color to bright red but the TabFolder background color was unimpressed.</p> <p>So the SWT buttons don't set their background color correctly themselves and I see no way to find out the correct color programatically. What should I do?</p> <hr> <p>Anyway, here is the code for a complete minimal example to reproduce the problem:</p> <pre class="lang-java prettyprint-override"><code>import org.eclipse.swt.SWT; import org.eclipse.swt.layout.RowLayout; import org.eclipse.swt.widgets.Button; import org.eclipse.swt.widgets.Composite; import org.eclipse.swt.widgets.Display; import org.eclipse.swt.widgets.Shell; import org.eclipse.swt.widgets.TabFolder; import org.eclipse.swt.widgets.TabItem; public class TabTest { public static void main(String[] args) { Display display = new Display(); Shell shell = new Shell(display); TabFolder tabFolder = new TabFolder (shell, SWT.NONE); TabItem item = new TabItem (tabFolder, SWT.NULL); item.setText ("Tab Item"); Composite comp = new Composite(tabFolder, SWT.NONE); comp.setLayout(new RowLayout()); item.setControl(comp); Button button = new Button(comp, SWT.PUSH); button.setText("Button "); tabFolder.setSize (160, 100); //Event Loop shell.pack (); shell.open (); while (!shell.isDisposed()) { if (!display.readAndDispatch()) display.sleep(); } display.dispose(); } } </code></pre>
