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
