ui.Window.getCurrent

Get the current window object.

Syntax

ui.Window.getCurrent()
  RETURNS ui.Window

Usage

The ui.Window.getCurrent() class method returns the ui.Window object corresponding to the current window.

Declare a variable of type ui.Window to hold the window object reference.

When invoking the ui.Window.getCurrent() method to get the initial default "screen" window, an OPEN FORM/DISPLAY FORM must have been executed. Otherwise, the method will return NULL.

Tip: When no form is yet displayed, and you want to get the default "screen" window object before any dialog instruction, use the CURRENT WINDOW IS screen instruction, then use ui.Window.getCurrent(). When the first dialog is a MENU instruction and no form is yet displayed, the ui.Window.getCurrent() method can be called in the BEFORE MENU block. See ui.Window.setText() for an code example. See also ui.Window.createForm(), to create a form dynamically in the initial "screen" window.

Example

DEFINE w ui.Window
OPEN WINDOW w1 WITH FORM "custform"
LET w = ui.Window.getCurrent()
