Smooth animation (Java SWT) -

-

I have a question about animation drawing in Java (SWT). I try to attract some process animation. When I use the CanvasRread () program, it first erases everything that has been pulled and then pulls it again. Approximately 1000 rectangles in my program come at a per-time step (this big quantity is required), so the animation does not look smooth - it blinks all the time for example, for painting new objects on old objects, without erasing them ( Which will look better anyway) is this easy way?

Fixing instability when using custom painting is to use double buffering, SWT canvas object is built in double-buffering Use it by adding the flag to the styles in the constructor: 

  canvas myCanvas = new canvas (parent composite, SWT.DOUBLE_BUFFERED);

I have performed a linq query using Entityframework as below GroupMaster getGroup = Null; GetGroup = DataContext.Groups.FirstOrDefault (item = & gt; keyword.IndexOf (item.Keywords, StringComparison.OrdinalIgnoreCase)> = 0 & amp; amp; item.ISNAmd) I found an exception like the method when executing it LINQ units do not recognize the 'Inter 32 index of (system string, system. String compromise)' method, and This method can not be translated to Store expression. Includes () method is sensitive by default, then I need to convert to minimize. Is there any method in which a string match match is examined and whether there is any method to solve the index question of the method? You actually have four options Databases globally Change the colon of it can be done in many ways, a simple Google search should reveal to them. Change the mix of individual tables or columns. Use a stored procedure and specify the call statement on your query Perform...
