This keyword is not expanded by Git which means it's not replaced with the correct revision value in the releases made using git-based scripts and it's confusing to have lines with unexpanded "$Id$" in the released files. As expanding them with Git is not that simple (it could be done with git archive and export-subst attribute) and there are not many benefits in having them in the first place, just remove all these lines. If nothing else, this will make an eventual transition to Git simpler. Closes #14487. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@74602 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775

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).

|
|
@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
