The movie area is QMedia Light's plug-in area that is used to play back movies.
It is a typical plug-in area in 4D; like most other plug-in areas, it is identified by a long integer variable that is assigned to the plug-in area in 4D's form editor. The plug-in area identifier is referred to in this manual as "movie area reference" or "area reference".
Creating a movie area
To create a movie plug-in area on a form, select _QMovie as the type of plug-in area from the properties palette.
Area visibility
QMedia includes two specific commands, QM_SetAreaVisible and QM_GetAreaVisible, to control the visibility of a movie area. Use QM_SetAreaVisible rather than 4D's SET VISIBLE command in order to show or hide the movie area object.
Showing a movie on a list form
QMedia's plug-in area can not be placed on list forms (output layouts) as is. However, you can display a movie picture in a list form. Use QM_GetMoviePict to get the corresponding picture into a standard 4D picture object.
Printing a movie snapshot
QMedia's plug-in area can not be printed as is. You can print a snapshot of a movie after getting the corresponding picture with the QM_GetMoviePict command into a printable 4D object.
