About pop-up forms
You can design your form as a floating pop-up window. In a pop-up form, form open, explorer, and Multiple Document Interface (MDI) options are disabled. All windows and tabs behind a pop-up window are disabled. All toolbar and menu options are available in tabbed and MDI format.
Any form launched from a modal form is also launched as a modal form, regardless of the event used to launch the form. Forms opened as modal forms are not added to the MRU list.
To set up a form as a pop-up form, select [Popup Windows] in the [Specify Form Run Options] dialog box.
To design a pop-up form, design a form as you normally do, with the dimensions that you want the modal form to be, in both MDI and tabbed form layout.
To display a toolbar in FormOnly mode, set a form-level variable DisplayMobileToolbar. This variable can have the values [none], [top], [bottom], or [both]. If the variable is set to any value other than [none], the toolbar is displayed at the top of the form.
Standard form buttons are shown only if standard operations on the form are enabled (specifically Save, Filter, New, and Delete).
