Remarks

"Request for refreshing the display" process

One of the processes associated with the windows, internal windows, control templates and superccontrols is the "Request for refreshing the display" process. This process is used to group the code for updating controls: content of controls, status (visible, grayed, ...), static to update, ...
This process may expect parameters. All you have to do is declare a procedure in the process. For example:
// Request for refreshing the display
PROCÉDURE AskForRefresh(RefreshType is boolean)
This process is started upon request by the following functions:
  • RequestUpdateUI: Runs the process at the end of current process (asynchronous execution).
  • ExecuteUpdateUI: Runs the process immediately.
  • RequestUpdateUIParent: Runs the process of higher level at the end of current process (asynchronous execution).
  • ExecuteUpdateUIParent: Immediately runs the process of higher level.
During the call to these functions, you have the ability to specify the value of parameters expected by the process.
Note: The "Request for refreshing the display" process can also be immediately run by ExecuteProcess with the following syntax:
ExecuteProcess(<Element Name>, trtRequestUpdate)
