Finally it is up & running! Our GanttProto demo application is up on appspot.com. My goal was to see how such a complex visual control can be done in the browser after one developer told me that it was impossible :-) I did have a suspicion that it is doable, based on my experience with the Calendar control, but you never know… :-) At the same token it is also a good test-case for our PMAP Grid control (coming in another announcement soon).

Read on for technical details…

Today we released version 20070925 of the PMAP tree view component with some quick fixes.

Highlights:

• Enhanced Opera keyboard support (still with some visuals issues)
• Fixed a bug when clicking to the left of a leaf node (thanks JM!)
• Surfaced getTreeNodeByExternalID() so that you can use it to find a particular node of interest independently of the tree structure or of the actual (language dependent) title of the node (you will have to set the external ID before using this function ;-)
• The demo app displays the version string of the tree control in the Log upon startup.

Our PMAP partners are receiving the latest builds today.

Happy coding!

Today we released version 20070912 of the PMAP tree view component.

Highlights:

• Fully supports Safari and works on Opera (with some keyboard handling and visuals issues)
• A new property (SelectionColor) is introduced to make it easier to set the selection color (no need for editing the css file any more)
• Tree nodes now can be expanded with the left & right arrow keys in addition to using Enter
• The demo app has been updated.

Our PMAP partners are receiving the latest builds today.

Happy coding!

We have released the initial documentation set for the tree view control here in the blog.

Please go to the PMAP page and then click on the Navigation panel on the right to access the documentation.

Make sure you drop your comments so that we know what you would like to see improved!

Dear Friends!

As you may be well aware, we have just launched the PannonRex Morfik Advantage Program during the weekend, with the Tree View control as a first item. Now I created a PMAP page on this blog to summarize the program details. Please review and comment!

Thanks,
Peter

Here is our first PMAP control: the Tree View. Please look at the demo in Morfik Labs (as soon as it is up) (it is uploaded!).

Our new Tree View will allow you to build trees of virtually any complexity, even containing HTML and the ability to command other parts of your user interface. It has been optimized to keep its performance sustained even with large trees. The PMAP code set contains both the full source code of the tree control and the continuously growing infrastructure functions we are using to build high performance controls and applications.

Some highlights:

• Full keyboard navigation.
• Multiple levels of customizability (style sheet, properties, events, etc.).
• Any tree node can contain valid HTML.
• Build the tree either through the control API, or with the help of XML or JSON.
• Performance optimized.
• Multiple selection support (with keyboard navigation, too!).
• Fixed height or elastic sizing based on content.
• Dynamic loading API for huge trees.

A few words about the demo:

• The default tree demonstrates a few things, like embedded hyperlinks, user interface commanding (will turn the pages in the Tab control in an event handler), and various icons.
• You can edit this tree or create your own in many ways
  • by building it up node-by-node,
  • by adding complete sub-trees defined in JSON format,
  • by specifying the entire tree in XML or JSON format, or
  • by generating a tree based on some parameters.
• You will notice that using the JSON interface is much faster than the XML interface. This is indeed a good comparison of the JSON v.s. XML support of your browser (see the Log for timing data).
• You will be able to customize many of the node and tree options.
• How to use the Items page:
  • First press “Set Items (XML)” (and be patient;-: it will set up a test tree that is in the editor on the right in XML format.
  • Then press “Get Items (JSON)”: the editor will be filled with the JSON version of the same tree.
  • Careful: press “Clear” below the tree control, to make the tree empty (it is lovely to have so many Clear buttons:-).
  • Now press “Set Items (JSON)”: your tree will be re-built much faster (just look at the log, on some configurations the difference can be 50 fold+!).
  • If you want to get back the original tree, just press “Default content”.

Feel free to play with the control and let us know of your findings (either by commenting here or by dropping a mail).

Our PMAP service augments the strong out-of-the-box offering of Morfik 07 to make it the ultimate development platform for mission-critical web applications for small shops and enterprises alike.

Developing any application has two aspects: you have to develop your business logic, data storage and presentation (the solution to your problem), and you have to develop the infrastructure upon which your solution operates. Developing the infrastructure in a web application environment is challenging because the underlying technologies are complex, inconsistent, and numerous – you have to deal with browser limitations and incompatibilities, security issues, performance problems and a great number of quickly evolving technologies, to name a few challenges. In PMAP we work hard for you to hide the infrastructure complexities to help you focus on your solution.
