Processes managed by default
WINDEV and WINDEV Mobile manage the following processes by default (in the order in which they appear in the code editor):
ProcessRuntime condition
Declaration of global variablesDeclaring the variables global to the window. This is the first code run when opening the window.
Initialization (before version 180062)
End of initialization (after version 180062)
End of initialization
Run when opening the window.
The processes are run in the following order:
  • Initializing the window controls (*)
  • Initializing the window
  • Gain of focus
Note: A blinking effect may occur if code for updating the controls is included in this process. Indeed, the initialization code of controls is run before the update code.
ClosingRun when closing the window.
Note: Resuming the input in one of the window controls in this code prevents from closing the window.
Versions 20 and later
Request for refreshing the display
New in version 20

  • the user clicked another application window
  • ReturnToCapture was run from another application window
This process will not be run:
  • when opening the first project window.
  • when running OpenChild or OpenSister from the current window.
  • if Close is called in the initialization code of window.
  • if the user clicks a window of another program then re-clicks the initial window.
This process will not be run:

Loss of focusRun when the window loses focus when going to another window. This process is always called before the process for taking focus of another window in the following cases:
  • closing the window (before the closing process)
  • the user clicked another application window
  • ReturnToCapture was run from another application window
This process will not be run:
  • if ReturnToCapture toward another window was run in the initialization code of window
  • if Close is called in the initialization code of window
  • if the user clicks a window of another program then re-clicks the initial window
