java - LayoutPanel getOffsetWidth() returns 0 -


I can not find the actual dimensions of an object when she went the first time and expense by LayoutPanel. I'm using the layout panel for a widget of up to percent: 

  MyClass displayObject = new MyClass (); Adding (DisplayObject); SetWidgetLeftWidth (displayObject, 0.0, Unit.PCT, 15.0, UnitPCT); SetWidgetTopHeight (displayObject, 0.0, Unit.PCT, 30.0, Unit PCT);

class I onResize () override: 

  implement public MyClass extends AbsolutePanel does RequiresResize {@Override public void onResize () {int maxWidth = getOffsetWidth ( ); Integer maxHeight = getOffsetHeight (); // ... here need to use maxWidth ...}}

My problem is that onResize () until the browser is physically added to the given size , And when I need the correct dimension the object is displayed first.

If I forceLayout () is called, it makes a call to onResize (), but getOffsetWidth () returns null. I need to force a call to execute onResize () after that the object is composed of pieces.

You browser should give a little time to complete the first layout of asking for a size: . 

  Scheduler.get () scheduleDeferred (New ScheduledCommand () {@Override public void execute () {int maxWidth = GetOffsetWidth (); int maxHeight = getOffsetHeight (); // etc.}} ); You can read more here:

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. 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...
