Close Parent window while closing child window

Below pseudo code can be only used if child window is Standard Oracle form. If child window is custom then use close_window() or exit_form.

Pseudo logic
==========

Declare a parameter/global variable.
Initialize variable on PUSH_BUTTON  before opening child window.

When child window closes the cursor returns to the same item(PUSH_BUTTON) on main window.

Use below code in WHEN-NEW-ITEM-INSTANCE trigger of PUSH_BUTTON on main window to close parent window as soon as cursor returns back from child.


declare
  form_id FORMMODULE;
BEGIN
  IF :parameter.form_close = 'Y' THEN
    form_id := FIND_FORM(NAME_IN('SYSTEM.CURRENT_FORM'));
    IF NOT ID_NULL(form_id) THEN
      CLOSE_FORM(form_id);
    END IF;
  END IF;
END;

You can also use exit_form instead of close_form;
