Property access for read and write
This property is also functional for Web panels.
Defining this method is often important, for example, if opening a modal window for data editing. The ReturnValue
property is then used as output value.
See How to work with modal windows.
If the OpenView
method vas used to open this panel and the oExtra.onClose
entry was defined then while closing this panel the user method defined here is executed. This user method has two parameters oSystem
represented by PmMap
type objects. The output value of the closed pan can be obtained in this method by using the oSystem.ReturnValue
For the old procedure of modal window opening by the PmPanel.OpenViewModal
method, this value is used as method return value.
This property can be set, for example, in the onPanelStopEnd
event when the panel is being closed. But it can also be set any time before that.
