— Function File: uiwait
— Function File: uiwait (h)
— Function File: uiwait (h, timeout)

Suspend program execution until the figure with handle h is deleted or uiresume is called. When no figure handle is specified, this function uses the current figure.

If the figure handle is invalid or there is no current figure, this functions returns immediately.

When specified, timeout defines the number of seconds to wait for the figure deletion or the uiresume call. The timeout value must be at least 1. If a smaller value is specified, a warning is issued and a timeout value of 1 is used instead. If a non-integer value is specified, it is truncated towards 0. If timeout is not specified, the program execution is suspended indefinitely.

— Function File: uiresume (h)

Resume program execution suspended with uiwait. The handle h must be the same as the on specified in uiwait. If the handle is invalid or there is no uiwait call pending for the figure with handle h, this function does nothing.

— Built-in Function: waitfor (h)

— Built-in Function: waitfor (h, prop, value)
— Built-in Function: waitfor (..., "timeout", timeout)

Suspend the execution of the current program until a condition is satisfied on the graphics handle h. While the program is suspended graphics events are still being processed normally, allowing callbacks to modify the state of graphics objects. This function is reentrant and can be called from a callback, while another waitfor call is pending at top-level.

In the first form, program execution is suspended until the graphics object h is destroyed. If the graphics handle is invalid, the function returns immediately.

In the second form, execution is suspended until the graphics object is destroyed or the property named prop is modified. If the graphics handle is invalid or the property does not exist, the function returns immediately.

In the third form, execution is suspended until the graphics object is destroyed or the property named prop is set to value. The function isequal is used to compare property values. If the graphics handle is invalid, the property does not exist or the property is already set to value, the function returns immediately.

An optional timeout can be specified using the property timeout. This timeout value is the number of seconds to wait for the condition to be true. timeout must be at least 1. If a smaller value is specified, a warning is issued and a value of 1 is used instead. If the timeout value is not an integer, it is truncated towards 0.

To define a condition on a property named timeout, use the string \timeout instead.

In all cases, typing CTRL-C stops program execution immediately.
