I have aViewPart and want to use a "org.eclipse.swt.widgets.Scale" to zoom a
Figure inside the view.
For that matter I created the method below:
private void createToolBar() {
IToolBarManager mgr = getViewSite().getActionBars().getToolBarManager();
IContributionItem control = new ControlContribution("Scale") {
public Control createControl(Composite parent) {
Scale scale = new Scale (parent, SWT.HORIZONTAL);
scale.setMinimum(1);
scale.setMaximum(19);
scale.setSelection(10);
scale.setPageIncrement(3);
scale.setIncrement(1);
scale.addSelectionListener(new SelectionListener() {
public void widgetSelected(SelectionEvent e) {
int sel = ((Scale)e.getSource()).getSelection();
((ScalableFreeformLayeredPane)view).setScale((double)sel/10) ;
}
public void widgetDefaultSelected(SelectionEvent e) {}
});
return scale;
}
public int computeWidth(Control control) {
return control.computeSize(100, SWT.DEFAULT, true).x;
}
};
mgr.add(control);
mgr.add(new Separator());
}
The problem: the Scale height is larger than the ToolBar height. How can I
make the Scale fit inside the ToolBar's borders?
I tried different approaches (including setLayoutData(new GridData()) and so
forth) but didn't help.
Thanks,
F
