java - Using different layouts in GUIs -

-

That's my program should look like this and I'm a little confused why I should use different layouts.

I have a window class that calls the panel class and the panel calls the class input panel and the display panel class. My InputPlan class calls my details panel, the Cranial Panel and the Button Panel classes so that they can be seen under the input tab. I was asked to use a border line for the entire window, and that the DetailsPanel (left panel) and Crime Panel should have a grid layout.

What this means should be:

  1. Border layout code in the panel and the grid layout code in the Crime panel and details panel or
  2. Borders in the window Keep the layout code and gridlove code in the panel?

OK, your description is a bit confusing (or I am still very tired or not enough caffeine yet).

But as far as I can see it, your first option is correct.

Normally you nest on object runtime, it may look like this: 

  InputPanel + (Border Layout) + - DescriptionPanel (put in border layout. West ; Gridlove is). + - Name label | + - NameTextField | + --... + - Crim Panel (enter in border layout, North; is grid layout). + - KillReadyButton | + - Arnson Radiot Button | + --... + - ButtonPanel (Border layout has been inserted; Grid layout) + - Button

You usually do this in the appropriate category manufacturer: 

  public class input page {public input panel () {this.setLayout (new border layout ()); This.add (new detailspanel), border layout. West); This.add (New Crop Panel (), Border Layout. North); This.add (new button (panel), border layout .a); }} Public Class Details Panel {JLabel nameLabel; JTextField nameField; // ... public statementPanel () {this.setLayout (new gridlate (5, 1)); Name label = new jlabel ("name"); NameField = new JTextField (); // ... this.add (nameLabel); This.add (nameField); // ...}} ...

However, I see a small problem here: Since GridLayout is used to span multiple columns Do not allow other panels to be nested in the DetailsPanel on the left side, you can participate with a single GridBagLayout , which has the necessary capabilities, or you are there Nestle the other panels: 

  DetailsPanel (is the border layout) + - Panel 1 (Grid layout with 2 rows Enter in column 1; border layout. North) | + - Name label | + - NameField + - panel2 (grid layout with 3 rows, 2 columns; borderout has been inserted in the seatier) + - Defined + - Delal + + - Monthfield + --...

I am getting an error with php in order to format mysql_query () in php to format this string What is the right way? SELECT SELECT SELECT (*) Agents @AgentCount; User_Agent_English, User_Angent_Oursal, US.___Gent_Aginal, COUNT (User_Agent_Percade) ACC, COUNT (*) / (AgentCount) Percentage by agents user_agent_preser order DEC limit limit 50; In PHP, how am i setting $ query $ query = "SELECT count (*) agents @ agentcount; SELECT user_agent_parsed, User_agent_original , COUNT (user_agent_parsed) ascount, COUNT (*) / (@AgentCount) as a percentage by user_agent_parced by URI date DESC limit 50 "; This exact query will work properly if I put it in MySQL directly through a command line session. Do I need to release two separate php calls from mysql_query () and store the results first? I get the following error: There is an error in your SQL syntax; Instead of using a sub-selection and instead of using the 'SELECT user_agent_parsed, user_agent_original, ne...

url rewriting - How to implement the returnurl like SO in PHP? -

-
This URL should work even after the rewrite. Is this possible? Otherwise, I can only hardcoded everything If you are trying to create a login system with redirection You need to use the HTTP_REFERER header to find out where the user came from so that you can send it back there. The best way to do this is to use something like this in your login form: // - Login php & Lt; Input type = "password" name = "password" /> & Lt; Input type = "hidden" name = "returnrelale" value = "& lt ;? php echo $ redirectURL ;? & gt;" / & Gt; & Lt; / Form & gt; Please note that some ISP, browser or proxy will delete the referrer header, so you can not rely on each user to work fully. If you use a statement, to check whether the header exists or not, you can send those users back to the homepage or whatever. Edit If you are looking to use $ _SERVER ['REQUEST_URI'], if you are running Apache It sho...

Which Python client library should I use for CouchdB? -

-
I am starting to experiment with CouchDB because it looks like we have the right solution to certain problems That all the work will be on a new project, which does not have any legacy dependency, which the client library will suggest you use, and why? If we overlap any of the OS. Freeband is available only in the collection of its ports, but asks to use the library's project website. None of those people are Ubuntu, which is only with ships, since those two OSAs are not common in libraries, I am probably installing something from source (and hopefully if I have time, then Ubuntu and FreeBSD People pack the package). For those interests, I want to use CouchDB as a convenient intermediate storage space for data passed between different services - think of a message bus system, but less formalities with. For example, we have daemons that download and pars the web page, then send an interesting bit to other daemons for further processing. Many of them are ill-defined until the...
