Animator for implementing fade-ins and fade-outs.
This animator is an utility class to animate the opacity parameter of widgets.
|
static |
Apply a fade-out animation and delete the given widget.
Once the fade-out has been completed, the widget is deleted, by removing it from its parent. The input flags are set to zero immediately.
| w | target widget |
| duration | duration of the fade-out animation in seconds |
| predelay | delay in seconds before the fade-out is started |
|
static |
Apply a fade-out animation and hide the given widget.
Once the fade-out has been completed, the widget is hidden. The input flags are set to zero immediately.
| w | target widget |
| duration | duration of the fade-out animation in seconds |
| predelay | delay in seconds before the fade-out is started |
