WindowActionsEventArgs

Namespace: PPJ.Runtime.Windows

Assembly: PPJ.Runtime.50 (5.0.0.0)

Carries a SAL window action's message code, native parameters, target handle, and processing result.

C#

public class WindowActionsEventArgs : EventArgs

VB.NET

Public Class WindowActionsEventArgs
    Inherits EventArgs

Setting Return also sets Handled and HasReturnValue. Setting Handled alone does not supply a return value.

Example:

void HandleAction(object sender, PPJ.Runtime.Windows.WindowActionsEventArgs e)
{
    System.Diagnostics.Debug.WriteLine(e.ActionType);
    e.Return = 1;
    // Handled and HasReturnValue are now true.
}
