Synopsis

progressWindow [-endProgress] [-isCancelled boolean] [-isInterruptable boolean] [-maxValue int] [-minValue int] [-progress int] [-status string] [-step int] [-title string]

progressWindow is undoable, queryable, and editable.

The progressWindow command creates a window containing a status message, a graphical progress gauge, and optionally a "Hit ESC to Cancel" label for interruptable operations.

Only one progress window is allowed on screen at a time. While the window is visible, the busy cursor is shown.

Return value

booleanReturns true if the window was successfully created, and false if the window could not be created (possibly because one is already showing).

In query mode, return type is based on queried flag.

Flags

endProgress, isCancelled, isInterruptable, maxValue, minValue, progress, status, step, title
Long name (short name) Argument types Properties
-isCancelled(-ic) boolean query
Returns true if the user has tried to cancel the operation. Returns false otherwise.
-progress(-pr) int createqueryedit
The amount of progress currently shown on the control. The value will always be between min and max. Default is equal to the minimum when the control is created.
-step(-s) int edit
Increments the -pr/progress value by the amount specified.
-minValue(-min) int createqueryedit
The minimum or "starting" value of the progress indicator. If the progress value is less than the -min/minValue, the progress value will be set to the minimum. Default value is 0.
-maxValue(-max) int createqueryedit
The maximum or "ending" value of the progress indicator. If the progress value is greater than the -max/maxValue, the progress value will be set to the maximum. Default value is 100.
-title(-t) string createqueryedit
The window title.
-status(-st) string createqueryedit
The status text appearing above the progress gauge.
-isInterruptable(-ii) boolean createqueryedit
Returns true if the progress window should respond to attempts to cancel the operation. The cancel button is disabled if this is set to true.
-endProgress(-ep) create
Terminates the progress window. No other flags can be used at the same time. This is normally issued through MEL in response to the -ic/isCancelled flag being set or if the progress value reaches its maximum.
Flag can appear in Create mode of command Flag can appear in Edit mode of command
Flag can appear in Query mode of command Flag can be used more than once in a command.
