Re: how can i do export? – Jeff Johnston – – MarkMail

As similar questions get posted on the groups I will add those questions and answers to the Recipes page. Note that we’ve also left off the pk column as per requirements. We continue by introducing a more user-friendly value into the format column. How can we do that?

One thing I shouldn’t skip is the controller for the search results page, the page within which we will build our table. Each HelloWorld item produces a formatted string within its toString method. Developer Fusion – The global developer community for. This makes the page cleaner, gives me more functionality out-of-box, and enables me to nix at least some of the languages I’d otherwise have to fuss with. Brought to you in partnership with Red Hat.

Unfortunately, the HtmlCellRenderer sub-interface that comes with JMesa has no method for adding attributes. Again, a single line of code will do all we need:. That’s really all there is to it! Learn more about Kotlin. But recently I discovered an open-source Java library called JMesa that provides another way.

Putting It All Together We’ll refactor out reusable code expot more in writing a Factory to encapsulate building our customized table, esport with an abstract class: The WebContext provides umesa with the servlet context path, again jmdsa us avoid hard-coding the image URL:.


Contribute Why not write for us?

This means we won’t have to hard-code a part of the image URL. The only real information it conveys is that it is the default value.

Running the Table With JMesa

This “domain” object jmwsa be pretty easy to display:. There are two parts to the solution: If it is exported, the results will be written directly to the output stream of the response; if not, they’ll be fxport as a string containing our HTML table: Advanced Linux Commands [Cheat Sheet].

Its getValue method is passed the item to be displayed, the property to be called, and the current row count. Insight Into a Hybrid Approach. That’s all there is to it! We will display the value of each HelloWorld item’s toString method in an additional column We will display more user-friendly values in the format column We will ensure that columns that cannot be reasonably sorted are made unsortable We will add columns containing links to dxport and delete pages for the HelloWorld items We will display images in the edit and delete columns We will dxport display the Pk property of each item, but will pass its value to edit and delete pages as needed We will enable the user to retrieve a comma-separated-values CSV copy of the table contents We will enable the user to retrieve an Excel spreadsheet copy of the table contents We will disable filtering and highlighting We will reorganize the toolbar items in a different order Believe it or not, implementing each of these features will be quite easy!

But it would be awfully nice if the images could be centered within the column, something notoriously difficult to achieve with CSS style sheets. When this explrt is set, JMesa uses the Memento design pattern to save the state of jmfsa tables. The CoreContext has many uses; our immediate purpose for it is to retrieve a value configured in the jmesa.

You can find out more by reading the recipestutorialsand examples.

Since this is functionality I use a lot, let’s design it for reuse, refactoring out reusable code into one class, and code tailored to this project into another. Our tools We’ve got automatic conversion tools to convert C to VB. If you would like the JMesa jar file in the Maven repositories I have decided to leave it up to the community to finish the work started. Data APIs for Developers.


To fully customize this table is just as easy. When you return to a table page and include the attribute you specify here in the URL, you return to the exact place you left: There are a lot more configurable preferences: This is just one more branch on the decision tree we saw in the previous controller: This is just one more branch on the decision tree we saw in the previous controller:.

Making a column actually, we need to have an HtmlColumn, but most columns qualify unsortable is very simple:. Now we’ll add columns containing links to edit and delete pages for HelloWorld items. All that iterative logic simply looks incomprehensible to me.

Creating tables with JMesa is very easy. In addition there is support for grouping columns. The results show only the row containing Einstein’s name in the last name column. Don’t get me wrong: OK, you have to include some JAR files in the library, but what did you expect, magic? Finally, the table looks like we want it to, but it’s irritating having to resubmit the form each time we want to make a change. Those on the left are standard first, previous, next, and last navigation icons.

With this, no onClick method will be generated for the column header, preventing users from accidentally causing a mess.

Something to Display Another thing we need before we can build jemsa table is something to show in it. Also, defaults rarely exercise every feature, and this one is no exception.
