Hello there,
I'm new to RAP and tried to implement a dialog but unfortunately I've got
some problems. First my code:
package rap;
import inmt.web_service.INMTStub;
import org.eclipse.jface.dialogs.Dialog;
import org.eclipse.rwt.lifecycle.UICallBack;
import org.eclipse.swt.SWT;
import org.eclipse.swt.custom.CLabel;
import org.eclipse.swt.layout.GridData;
import org.eclipse.swt.layout.GridLayout;
import org.eclipse.swt.widgets.Composite;
import org.eclipse.swt.widgets.Control;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.swt.widgets.Text;
import org.webhmi.inmt.xsd.OwnUnitDataDocument.OwnUnitData;
import util.DataProvider;
import util.WaitDialog;
public class MyDialog extends Dialog {
private Text text1;
private Text text2;
private Text text3;
/**
* Constructor
*
* @param parentShell
*/
protected MyDialog(Shell parentShell) {
super(parentShell);
}
/**
* Creates a label, adds it and returns it
*
* @param parent
* @param text
* @return
*/
private CLabel getLabel(Composite parent, String text) {
CLabel label = new CLabel(parent, SWT.BORDER);
label.setText(text);
label.setLayoutData(getGridData(false));
return label;
}
/**
* Creates Textbox
*
* @param parent
* @return
*/
private Text getTextBox(Composite parent) {
Text text = new Text(parent, SWT.BORDER);
GridData griddata = getGridData(true);
text.setLayoutData(griddata);
return text;
}
/**
* Creates grid data
*
* @return
*/
private GridData getGridData(boolean fill) {
GridData griddata = new GridData(SWT.LEFT, SWT.CENTER, true, true);
if (fill) {
griddata.horizontalAlignment = SWT.FILL;
}
return griddata;
}
/**
* Creates the view of the Control
*/
protected Control createContents(Composite parent) {
WaitDialog.getInstance().close();
Composite top = new Composite(parent, SWT.NONE);
GridLayout layout = new GridLayout();
layout.numColumns = 2;
layout.marginHeight = 10;
layout.marginWidth = 10;
top.setLayout(layout);
getLabel(top, "Designator");
text1 = getTextBox(top);
getLabel(top, "FTN");
text2 = getTextBox(top);
getLabel(top, "SNC Version");
text3 = getTextBox(top);
parent.pack(true);
parent.setSize(400, 400);
return parent;
}
/**
* Configures the shell
*/
protected void configureShell(Shell shell) {
super.configureShell(shell);
shell.setText("My Dialog");
shell.setLocation(200, 200);
}
@Override
protected void createButtonsForButtonBar(Composite parent) {
// TODO Auto-generated method stub
super.createButtonsForButtonBar(parent);
createButton(parent, 10, "asda", true);
}
}
There are several problems:
1) The dialog had the problem that after the second opening I didn't
display the Text and Labels anymore. After adding pack()-call the problem
disappeared.
2) Now the buttons are never displayed although I added a call. Why?
3) How can I define new Colors without SWT-constants?
4) How can I center the dialog to the screen?
Thanks in advance,
Sebastian

Hi,
1) The dialog had the problem that after the second opening I didn't

problem
disappeared.
This is because you are overriding the wrong method. Use
Dialog#createDialogArea(Composite) instead of
Dialog#createContents(Composite). Doing so you don't have to call
Control#pack() and the buttons will reappear again.
2) Now the buttons are never displayed although I added a call. Why?
See anser to 1)
3) How can I define new Colors without SWT-constants?
Color red = Graphics.getColor( 255, 0, 0 );
4) How can I center the dialog to the screen?
By overriding the method Dialog#initializeBounds():
protected void initializeBounds() {
super.initializeBounds();
Rectangle displayBounds = Display.getCurrent().getBounds();
Point size = getShell().getSize();
int x = ( displayBounds.width - size.x ) / 2;
int y = ( displayBounds.height - size.y ) / 2;
getShell().setLocation( x, y );
}
Hope that helps!
Ciao
