The Msg method offered by the Interop external object enables displaying a message in a pop-up window.

InteropEO-MsgMethod

Below is an example of how this feature is used.

Step 1

Create a new Panel object.

Step 2

Define a variable based on VarChar(200). Suppose you call it &MsgPopup and it is present in the Panel Layout. This variable will allow entering a message to be shown in a pop-up window on the device.

Step 3

Add a new button in the Panel Layout (associated with an Event called PopMSG).

Step 4

Go to the event by double-clicking on the button and define the following code:

Event 'PopMSG'
    Interop.Msg(&MsgPopup)
EndEvent

Done! The entry Panel will accept a message and when the button is tapped, the text in a message dialogue will be prompted.

Since GeneXus 16 upgrade 9, the Msg method accepts two parameters: the message and the button text. For example: 

Event 'PopMSG'
    Interop.Msg("This is a test", "Ok, thanks")
EndEvent
