Method Detail

### onClick

    protected void onClick()

  Description copied from class: `CustomButton`
  Called when the user finishes clicking on this button. The default behavior is to fire the click event to listeners. Subclasses that override `CustomButton.onClickStart()` should override this method to restore the normal widget display.

  Overrides:
    `onClick` in class `CustomButton`

### onClickCancel

    protected void onClickCancel()

  Description copied from class: `CustomButton`
  Called when the user aborts a click in progress; for example, by dragging the mouse outside of the button before releasing the mouse button. Subclasses that override `CustomButton.onClickStart()` should override this method to restore the normal widget display.

  Overrides:
    `onClickCancel` in class `CustomButton`

### onClickStart

    protected void onClickStart()

  Description copied from class: `CustomButton`
  Called when the user begins to click on this button. Subclasses may override this method to display the start of the click visually; such subclasses should also override `CustomButton.onClick()` and `CustomButton.onClickCancel()` to restore normal visual state. Each `onClickStart` will eventually be followed by either `onClick` or `onClickCancel`, depending on whether the click is completed.

  Overrides:
    `onClickStart` in class `CustomButton`
