HIDE WINDOW

version 6.0.5

HIDE WINDOW {(window)}

The HIDE WINDOW command allows you to hide the window whose number was passed in window or, if this parameter is omitted, the current process frontmost window. For example, this command allows you to display only the active window in a process that consists of several processes.

The window disappears from the screen but remains open. You can still programmatically apply any changes supported by 4D windows.

To display a window that was previously hidden by the HIDE WINDOW command:

• Use the SHOW WINDOW command and pass the window reference ID.

• Use the Process page of the Runtime Explorer. Select the process in which the window is handled, then click on the Show button.

To hide all the windows of a process, use the HIDE PROCESS command.

This example corresponds to a method of a button located in an input form. This button opens a dialog box in a new window that belongs to the same process. In this example, the user wants to hide the other windows of the process (an entry form and a tool palette) while displaying the dialog box. Once the dialog box is validated, other process windows are displayed again.
