public class FVSlider extends javax.swing.JSlider implements javax.swing.event.ChangeListener, java.awt.event.MouseMotionListener, java.awt.event.MouseListener
Custom slider that acts as the scroll bar for theFVTable
. This slider listens for changes to the viewport and updates its position accordingly. Q. Why not just use the standardJScrollbar
that comes with theJScrollPane
? A. It's because we are viewing only a portion of the total file at any given time; if we used the standard scroll mechanism, it would size itself and its viewport according to that subset of the total file, while we want it to reflect the file in its entirety. Q. Why extend a JSlider for this custom scroll bar instead of a JScrollBar? A. The JSlider is much easier to customize, specifically when trying to adjust the size of the slider thumb. Functionally they are both acceptable for our purposes, but the ease of using the slider wins out.- See Also:

FVSlider
public FVSlider(javax.swing.JScrollPane scrollPane, FVTable table, ViewportUtility viewportUtility, ChunkModel model, ChunkReader reader, FVEventListener eventListener)
Constructor. Builds the UI elements and establishes event listeners.- Parameters:
scrollPane
-table
-viewportUtility
-eventListener
-model
-reader
-eventListener
-
-
-
Method Detail
-
setValue
public void setValue(long filePos)
Sets the value of the slider based on the given file position.- Parameters:
filePos
-
-
setMaximum
public void setMaximum(long fileSize)
Sets the maximum slider position given the size of the file. If the file position is greater than the maximum size of an integer, we just set it to that maximum size.- Parameters:
fileSize
-
-
syncWithViewport
public void syncWithViewport()
Updates the slider so it is in sync with the current position of the viewport. Note that this is only done if the mouse is NOT down; if it is, it means the user is moving the thumb and we should do nothing.
-
stateChanged
public void stateChanged(javax.swing.event.ChangeEvent e)
Invoked when the slider value has changed. When this happens we need to update the viewport to match, but ONLY if this event is triggered as a result of the user manually moving the slider (and not as a result of the slider being moved programmatically in response to a viewport change).- Specified by:
stateChanged
in interfacejavax.swing.event.ChangeListener
-
mouseDragged
public void mouseDragged(java.awt.event.MouseEvent e)
MOUSE EVENTS We need to set the mouseDown attribute so we only initiate a viewport update if the slider is moving in response to user action on the slider.- Specified by:
mouseDragged

-
mouseMoved
public void mouseMoved(java.awt.event.MouseEvent e)
- Specified by:
mouseMoved
in interfacejava.awt.event.MouseMotionListener

mouseExited
public void mouseExited(java.awt.event.MouseEvent e)
- Specified by:
mouseExited
in interfacejava.awt.event.MouseListener
-
getFilePosition
public long getFilePosition(int sliderPos)
Returns the file position (long) for the given slider position (int). This is calculated by computing the position of the slider as a percentage of its maximum, and applying the same to the file position (relative to the total file size).- Parameters:
sliderPos
-- Returns:
