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 -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. 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.

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
