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

Windows doesn't let you set the height of a tool item. The only way do to
this right now is to insert an image with the right height to force the tool
bar to be taller.
public static void main(String[] args) {
Display display = new Display();
Shell shell = new Shell(display);
ToolBar toolBar = new ToolBar(shell, SWT.RIGHT);
Scale scale = new Scale(toolBar, SWT.NONE);
scale.pack();
int height = scale.getSize().y;
ToolItem scaleItem = new ToolItem(toolBar, SWT.SEPARATOR);
scaleItem.setControl(scale);
scaleItem.setWidth(128);
new ToolItem(toolBar, SWT.SEPARATOR);
ImageData imageData = new ImageData (1, height, 1, new PaletteData(new
RGB[] {new RGB(0, 0, 0)}));
imageData.transparentPixel = 0;
Image image = new Image (display, imageData);
for (int i = 0; i < 2; i++) {
ToolItem item = new ToolItem(toolBar, SWT.PUSH);
item.setText("Push " + i);
item.setImage(image);
}
toolBar.pack();
shell.pack();
shell.open();
while (!shell.isDisposed()) {
if (!display.readAndDispatch())
display.sleep();
}
image.dispose ();
display.dispose();
}

That's sad. It means that my Scale will always have to look bulky and ugly.
I thought there is a way to set its preferred size to a specific value. I
couldn't find a way myself and you're saying that actually is not even
possible.
What about the SWT Cotrols Example//"Slider/Scale". There is a radio button
group for Size. I cannot see the result for 10x10 but I was thinking that
the actual height of the Scale is reduced as well. Is it, or it's just the
bounds in which the Scale is contained?
Thanks,

Not sure what you are asking. The example code makes the tool bar tall
enough to show the scale without clipping.

some preferred height without any chance to modify it. I can change the
width no problem, but not the height.
No, I didn't ask how to make the ToolBar tall enough to show the Scale
properly.
Do you have an answer to my question now?
Thank you,

Use setSize() to set the width and height of the scale, not pack(). If the
size is too small, the scale will draw clipped, which is probably not what
you want. There is no way to tell the scale to draw smaller and not be
clipped.

I had the same problem:
Using a scale seemed the perfect tool for one of my wizards, but it just looks
ugly in it's prefered size (much larger than everything else).
Since the scale clips when reaching a certain height, I had to find a compromise
where the size did not make the page ugly, but the user can still operate the
slider. Actually I set the size so that only the slider and the upper scale
markings are visible.
Since I was using a GridLayout, I managed this by giving the scale a GridData
object with gridData.heightHint field set to about 22.
It would be really nice to have a scale that doesn't look unproportionally big
in a view or dialog page. If anyone knows a solution to this problem, please, I
would be happy to learn about it!!
