qt - Invert the wheel or keyboard arrow function in QDateTimeEdit -


I am using QDateTimeEdit to select the date and time for the user. Is there any way I can reverse in response to the mouse wheel and keyboard arrows?

For example, the default setting time or date causes the up-arrow press (or scroll) to increase. Can I change this setting, Due to the fall of the date?

(I am a rank newbie for QT, so please let me know that has been answered before!)

As an indication, you need to re-implement those virtual functions: 

  Zero KeyPressEvent (QKeyEvent * event) Zero Mousepress Event (QMouseEvent * event )

c# - Showing a SelectedItem's Property -

Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ...
