Eclipse 2.1.2
Java 1.4_x
1) I select multiple controls (inside a group control)
2) Select Copy (right-click)
3) Select Paste (right-click)
4) Place the controls
The copied controls appear, but some properties were not preserved:
-layoutData.hAlign (reset to left)
-layoutData.hSpan (reset to 1)
Also, I can no longer select controls with the mouse in the preview area. I have to select them from the tree. After selecting a control from the tree, then I can go back and select them like normal from the preview window.
Here's the exceptions I get after pasting the controls and trying to click on one:
- Code: Select all

Here's the sample code if you desire:
- Code: Select all
protected Control createContents(Composite parent) {
Composite thisComposite = new Composite(parent, SWT.NONE);
thisComposite.setLayout(new GridLayout());
{
final Group grpConfig = new Group(thisComposite, SWT.NONE);
grpConfig.setText("Configuration Files");
grpConfig.setLayoutData(new GridData(GridData.FILL_HORIZONTAL | GridData.VERTICAL_ALIGN_FILL));
final GridLayout gridLayout = new GridLayout();
gridLayout.numColumns = 3;
grpConfig.setLayout(gridLayout);
{
final Label lblLocalConfig = new Label(grpConfig, SWT.RIGHT);
lblLocalConfig.setLayoutData(new GridData(GridData.HORIZONTAL_ALIGN_FILL));
lblLocalConfig.setText("Local Configuration:");
}
{
final Text txtLocConfig = new Text(grpConfig, SWT.BORDER);
txtLocConfig.setLayoutData(new GridData(GridData.FILL_HORIZONTAL));
}
{
final Button cmdOpenLocConfig = new Button(grpConfig, SWT.NONE);
cmdOpenLocConfig.setLayoutData(new GridData(GridData.HORIZONTAL_ALIGN_FILL));
cmdOpenLocConfig.setText("...");
}
{
final Label label = new Label(grpConfig, SWT.RIGHT);
label.setLayoutData(new GridData(GridData.HORIZONTAL_ALIGN_FILL));
label.setText("Last Modified:");
}
{
final Label label = new Label(grpConfig, SWT.NONE);
final GridData gridData = new GridData(GridData.HORIZONTAL_ALIGN_FILL);
gridData.horizontalSpan = 2;
label.setLayoutData(gridData);
label.setText("N/A");
}
{
final Label lblProjConfig = new Label(grpConfig, SWT.RIGHT);
lblProjConfig.setLayoutData(new GridData(GridData.HORIZONTAL_ALIGN_FILL));
lblProjConfig.setText("Project Configuration:");
}
{
final Text txtProjConfig = new Text(grpConfig, SWT.BORDER);
txtProjConfig.setLayoutData(new GridData(GridData.FILL_HORIZONTAL));
}
{
final Button cmdOpenPrjConfig = new Button(grpConfig, SWT.NONE);
cmdOpenPrjConfig.setLayoutData(new GridData(GridData.HORIZONTAL_ALIGN_FILL));
cmdOpenPrjConfig.setText("...");
}
{
final Label lblProjLastModified_RO = new Label(grpConfig, SWT.RIGHT);
final GridData gridData = new GridData(GridData.HORIZONTAL_ALIGN_FILL);
lblProjLastModified_RO.setLayoutData(gridData);
lblProjLastModified_RO.setText("Last Modified:");
}
{
final Label lblProjLastModified = new Label(grpConfig, SWT.NONE);
final GridData gridData = new GridData(GridData.HORIZONTAL_ALIGN_FILL);
gridData.horizontalSpan = 2;
lblProjLastModified.setLayoutData(gridData);
lblProjLastModified.setText("N/A");
}
}
return thisComposite;
}
Try selecting the last two labels and copy/paste them to the next row.
Thanks,
Chad
