ACTIVATE MOVIE
PLBCMP GUI Only
The ACTIVATE MOVIE statement makes a MOVIE visible and allows the user to interact with it. An optional execution label may be provided to process information if the user selects the MOVIE. The instruction uses the following format:
|
|
|
|
|
Where:
label
Optional. A Program Execution Label.
movie
Required. The name of a previously created MOVIE object variable or a pointer to a MOVIE object.
routine
Optional. A program execution label called when a mouse click occurs within the screen boundaries of the object.
result
Optional. A previously defined Numeric Variable in which the result code as described below is placed upon object selection.
Flags Affected: NONE
Note the following:
The {routine} is only called when the DRAGITEM instruction is in effect.
The runtime performs no default action for the MOVIE object.
If the {result} operand is specified, it is set
to a nine-digit number describing the screen position where the mouse click occurred. The bottom four
digits describe the vertical position and the next four digits describe the horizontal position. The
ninth digit describes which button was clicked as follows:
|
Value |
Meaning |
|
0 |
The left mouse button was clicked. |
|
1 |
The right mouse button was clicked. |
|
2 |
The left mouse button was double clicked. |
|
3 |
The right mouse button was double clicked. |
If the {result} operand is too small to contain the value, the OVER flag is set upon entry to the {routine}. This flag setting does not occur at the time of the ACTIVATE butat the time the {routine} is called.
The {routine} is called as if a CALL instruction was performed. It is only called when an EVENTCHECK or EVENTWAIT is executed.
The {routine} is only called when the DRAGITEM instruction is in effect for the MOVIE object.
When the {routine} is complete, a RETURN instruction continues execution at the instruction following the EVENTWAIT or EVENTCHECK. Otherwise, a NORETURN instruction should be executed to clear the return address from the call stack.
All other object operations, such as movie controls, and screen updating are automatically performed by the runtime.
If the object specified by an ACTIVATE instruction is already active, the old {routine} and {result} operands are replaced with the new {routine} and {result} operands.
An object must be CREATEd before it is activated. If this is not done, a runtime error of O105 is generated.
If insufficient memory is available to perform the operation, a runtime error O106 is generated.
If a FILEPI instruction is active, it is terminated.
