public class PosZoomSlider
- extends JPanel
The zoom slider is in a popup dialog that shows when the "Show/Hide Zoom Slider" toolbar button is clicked.
To close the popup dialog, click the same toolbar button again.
The many classes in PclRenderImage and this PosZoomSlider in OpenPCLViewer and the action event methods in
PosOnSceen, all have code that work together to do the below 15 ways that the view image changes zoom:
1. Drag the slider bar pointer.
2. Click one of the slider buttons 10, 20, 30 to 100, 200, 300, 400
3. Click the Zoom Out toolbar button (zoom by 2% notches)
4. Key ctrl H also zooms out
5. Click the Zoom In toolbar button (zoom by 2% notches)
6. Key ctrl Z also zooms in
7. Click the Zoom Width button
8. Key ctrl I also zooms width
9. Click the "Show/Hide Tree" toolbar button to show and hide the tree
10. Key ctrl T also shows and hides the tree
11. Make the tree panel wider or narrower by dragger the splitter right or left
12. Click the Tile button on the toolbar that changes the view frame width
13. Click the Cascade button on the toolbar that changes the view frame width
14. Drag the right edge of the view frame right or left which will make it zoom width as you drag it
15. Mazimize/restore the view frame which will make it zoom width

PosZoomSlider
public PosZoomSlider(ChangeListener pSliderChangeListener,
ActionListener pButtonActionListener)
setZoomSliderLocationFromZoomFactor
public void setZoomSliderLocationFromZoomFactor(double pZoomFactor,
boolean pAllowImageToUpdate)
- Set the zoom slider location from the passed in zoom factor.
This method is called from 2 places, so the 2nd parameter passed is whether to let the image
update or not.
When this method is called from the direct zoom button action listener, true is passed
that allows the image to update to the new zoom factor. But when this method is called from all the
other many zoom events, then false is passed which doesn't let the image update because the
image has already updated from the original event.
setComponentsEnabled
public void setComponentsEnabled(boolean enabled)
- Enable/disable the slider and the direct access buttons. Used for:
1. Enabling the slider and buttons when one or more Viewer frames are showing.
2. and Disabling the slider and buttons when the last Viewer frame is closed and none is showing.
getAllowImageToUpdate
public boolean getAllowImageToUpdate()
- Get if the image is allowed to update. Used to stop the image from updating twice for double events
setAllowImageToUpdate
public void setAllowImageToUpdate(boolean pAllowImageToUpdate)
- Set if the image is allowed to update. Used to stop the image from updating twice for double events
