HIDE WINDOW 


 

HIDE WINDOW {( window )} 
Parameter Type   Description
window  WinRef in Window reference number or Current process frontmost window, if omitted

The HIDE WINDOW command hides the window whose number was passed in window or, if this parameter is omitted, the current process frontmost window. For example, this command lets you 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 apply any changes supported by 4D windows programmatically.

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.

Example  

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.

  ` Object method for the "Information" button
 
 HIDE WINDOW(Entry) ` Hide the entry window
 HIDE WINDOW(Palette) ` Hide the palette
 $Infos:=Open window(20;100;500;400;8) ` Create the information window
 ... ` Place here instructions that are dedicated to the dialog management
 CLOSE WINDOW($Infos` Close the dialog
 SHOW WINDOW(Entry)
 SHOW WINDOW(Palette) ` Display the other windows
