This is a static control which displays an animation.
|
||
|
wxAnimationCtrl API is as simple as possible and won't give you full control
|
||
|
on the animation; if you need it then use wxMediaCtrl.
|
||
|
|
||
|
This control is useful to display a (small) animation while doing a long task
|
||
|
(e.g. a "throbber").
|
||
|
|
||
|
It is only available if @c wxUSE_ANIMATIONCTRL is set to 1 (the default).
|
||
|
|
||
|
@beginStyleTable
|
||
|
@style{wxAC_DEFAULT_STYLE}
|
||
|
The default style: wxBORDER_NONE.
|
||
|
@style{wxAC_NO_AUTORESIZE}
|
||
|
By default, the control will adjust its size to exactly fit to the
|
||
|
size of the animation when SetAnimation is called. If this style
|
||
|
flag is given, the control will not change its size
