Modality
Determines whether the form instance can lose focus without being closed. Valid
values are Modal or Non-Modal (instance can
lose and get focus)
newinstance"A_FORM",
"MyInstance","modality=Non-Modal | Modal"
| Value | Description |
|---|---|
Non-Modal
|
The component instance can get and lose as a result of user action or the setformfocus ProcScript statement. |
Modal
|
Component instance retains focus until closed. |
Description
The Modality property can be set in the Properties Inspector for all component instances, or in ProcScript when creating a new instance. For example, the following statement starts a non-modal form to be used for inquiry:
newinstance "MYFORM", "QUERY", "MODALITY=NON-MODAL;QUERY=TRUE"
For non-modal forms, ProcScript in the loseFocus and getFocus triggers determines if focus is allowed to shift from one form to another.
Note: When a non-modal form is tested from within the Uniface IDE, it is started as a modal form, overriding the Modality property that you have defined for the form. To test the form as a non-modal form, use the command line switch /tst; alternatively, you can create a small application that you can use for testing non-modal forms.
When a modal form instance is created with newinstance, it is attached to the instance that created it. This means that if a modal form instance is created by one non-modal form, even if another non-modal form activates its exec operation, the modal form instance is attached to the first non-modal form; that form will become active when the modal form stops.
