java - NetBeans form designer: Change layout after call to initComponents -


I have a class that spreads javax.swing.JPanel , it has a pocket button I have created a class in Netbeans Designer , like I have a initComponents () function called a Class Constructor.

What do I have to do when / when a function is called, then I change the layout of the second button, and the two buttons. Just do it: 

  add public zero seconds () {javax.swing.JButton secondButton = new javax.swing.JButton (); Add (Second Button, Java.A.T.BirdLyut.Setter); }

does not work, the new button is not visible I tried calling to invalid () , but no luck

  • How can I re-evaluate the layout?
  • If it is said that the function is called more than once, then which part of the layout / button is required to call the settlement ()?
  • If I can not use NetBean Designer, will it be easy to handle?

    • before adding the button to you BorderLayout.CENTER You have to set the panel layout. In addition, you must first add and add the button again and apply the modified () method to the panel.

    Change your addSecond () method below and it should work. / P> 

      Private Zero addSecond () {JButton secondButton = New JButton ("Button - 2"); This.setLayout (new border layout ()); Delete (firstButton); Addition (First Button, Border Layout, North); Add (Second Button, Border Layout, CA); Re-verified (); }

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...
