Call Example

Description

This advanced feature allows developers to configure a wait dialog for every server action just as you can with the pbShowWaitDialog property of the cWebButton class.

Instead of adding properties for every server action, a procedure is available that tells the JavaScript Engine to send an action in a specific mode. The SetActionMode procedure takes a message handle to the published procedure or function as a parameter.

Sample

This example shows how to show a wait dialog can be shown while processing the OnClick of a menu item (cWebMenuItem). Other action modes that are available are: scModeWait, which will lock the UI and show a wait cursor and scModeDefault, which doesn't lock the UI and doesn't show a wait cursor.

Object oMenuItem is a cWebMenuItem
    Set psCaption to "Long process"

    Procedure OnLoad
        Forward Send OnLoad

        Send SetActionMode (RefProc(OnClick)) scModeProgress "Please wait while sleeping..."
    End_Procedure

    Procedure OnClick
        //  Do something long
        Sleep 4
    End_Procedure

End_Object

When a server action triggers another server action (like ProcessDataSet on cWebList), then it will keep the wait dialog on the screen until the new server action is processed.

Sample

This sample shows how to combine SetActionMode with a callback button that allows for confirmation of process execution prior to starting the process.

Procedure LongProcess 
    Sleep 30
End_Procedure

WebPublishProcedure LongProcess

Object oWebButton1 is a cWebButton
    Set piColumnSpan to 0
    Set psCaption to "Progress Process with confirmation"

    Procedure ButtonCallback Integer eConfirmMode
        If (eConfirmMode=cmYes) Begin
            Send CallBack of oDemoDialogs (RefProc(LongProcess))
        End
    End_Procedure

    WebPublishProcedure ButtonCallback

    Procedure OnClick
        Send ShowYesNo Self (RefProc(ButtonCallback)) "Confirm executing LongProcess" 
    End_Procedure
End_Object

Procedure OnLoad
    Forward Send OnLoad
    Send SetActionMode (RefProc(LongProcess)) scModeProgress "LongProcess is running. please wait!"
End_Procedure

Note: You can only mark published messages that the client sends to the server this way.
