java - Custom Drawn Component Not Drawing Inside JScrollPane -


I was using Java JRE 1.6.7 and had a JCM apprent and a JScroll. I could not get double buffering to work on that which was always the result of a flicker. If I use canvas, then buffering has to be cared for, but it has to face when used in conjunction with JScrollPan.

So I hope to download JR 1.6.18 that one of these problems OK that JComponent inside JScrollPane is not coming exactly at all. It only pulls out the area outside of JComponent, as if the JSolPan is pulling it upwards except the boundaries.

Here is an example of a code which is not drawing..It is a 1-pixel wide area of ​​area where the drawing should be: 

  public zero color ( Graphics arg0) {Graphics2D graphics = (Graphics2D) arg0; Graphics.setColor (Color.WHITE); Graphics.fillRect (0, 0, (int) getWidth (), (int) getHeight ());

Any help is greatly appreciated! Try to make override with paintComponent (graphics g) instead of

Colors (Graphics G) . Paint is a common method that you have to override for costume drawing.

Are you sure you can see white rectangle, try red or something else that you can see good.

I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
