move_rectangle

move_rectangle ( : : WindowHandle, Row1, Column1, Row2, Column2, DestRow, DestColumn : )

Copy inside an output window.

move_rectangle copies all entries in the rectangle (Row1,Column1), (Row2,Column2) of the output window to a new position inside the same window. This position is determined by the upper left corner (DestRow, DestColumn). Regions of the window, which are "uncovered" through moving the rectangle, are set to the color of the background.

If you want to move several rectangles at once, you may pass parameters in form of tupels.

Parameters

`WindowHandle` (input_control)	window `->` integer
Window identifier.

`Row1` (input_control)	rectangle.origin.y(-array) `->` integer
Row index of upper left corner of the source rectangle.
Default value: 0
Typical range of values: `0 <= Row1 <= 511` (lin)
Minimum increment: 1
Recommended increment: 1

`Column1` (input_control)	rectangle.origin.x(-array) `->` integer
Column index of upper left corner of the source rectangle.
Default value: 0
Typical range of values: `0 <= Column1 <= 511` (lin)
Minimum increment: 1
Recommended increment: 1

`Row2` (input_control)	rectangle.corner.y(-array) `->` integer
Row index of lower right corner of the source rectangle.
Default value: 64
Typical range of values: `0 <= Row2 <= 511` (lin)
Minimum increment: 1
Recommended increment: 1

`Column2` (input_control)	rectangle.corner.x(-array) `->` integer
Column index of lower right corner of the source rectangle.
Default value: 64
Typical range of values: `0 <= Column2 <= 511` (lin)
Minimum increment: 1
Recommended increment: 1

`DestRow` (input_control)	point.y(-array) `->` integer
Row index of upper left corner of the target position.
Default value: 64
Typical range of values: `0 <= DestRow <= 511` (lin)
Minimum increment: 1
Recommended increment: 1

`DestColumn` (input_control)	point.x(-array) `->` integer
Column index of upper left corner of the target position.
Default value: 64
Typical range of values: `0 <= DestColumn <= 511` (lin)
Minimum increment: 1
Recommended increment: 1

Example

/* "Interaktives" Kopieren eines Rechtecks im Ausgabefenster: */
draw_rectangle1(WindowHandle,L1,C1,L2,C2) 
get_mbutton(WindowHandle,LN,CN,Button) 
move_rectangle(WindowHandle,L1,C1,L2,C2,LN,CN).

Result

If the window is valid and the specified parameters are correct move_rectangle returns 2 (H_MSG_TRUE). If necessary an exception handling is raised.

Parallelization Information

move_rectangle is reentrant, local, and processed without parallelization.
