As usual massive thanks to last months presenters Sanyu Kiruluta and Tom Davies for 2 great talks last month. Both videos and presentations can be found in the presentations section.
This month we welcome back LFPUG regular Conrad Winchester with a session titled ‘Love at First Byte’ and following him, Steven Goodwin with a session on ‘Digital Archeology’.

Here’s a coverflow navigator layout for spark.
It supports virtual layout by either…
numUnselectedElements property which defines how many elements are shown either side or the selected element.numUnselectedElements has a value less than 0, the selected element is used to calculate the number of elements required to fill rectangle defined by the unscaledWidth and unscaledHeight. Note: this calculation uses the bounds of the selected element, and therefore if your elements are different sizes this could prove to be incorrect.Below is an example with a NavigatorGroup (bindable to a ButtonBar) and List (items can be selected by clicking on them), and some controls to edit the properties of the layout.
Huge thanks to David Kinross, Andrew Skinner & Tadhg McCarthy for the great talks last month. Both videos can be found in the presentations section.
This month Andre Fabris with a session on the ‘BlackBerry PlayBook Development Roadmap’ and following him, Tom Davies with a session on ‘Entity Systems – A Better Way to Develop Games’.

Here’s a MenuBar component for spark that takes an IList as a dataProvider (this can be a hierarchical list to build the menu).
The selectedIndices, selectedItems methods have been overridden so that they return the hierarchical selection, so for instance if you if selectedIndices has a value of 1,2,4 it means that at the root level, the second item has been selected (starts at 0), the third item within this has been selected and the fifth item within this has been selected.
It has a selectedLabels getter (i’ll add a setter very soon) that will return the labels of the selected hierarchical items. These strings can be used to show a breadcrumb trail
It has 2 other properties worth nothing. allowBranchSelection defines whether a branch can be selected, or whether only leaf nodes can cause selection to take place and closeOnSelection which defines whether the menu should close after a selection has been made.
It’s been ages since I posted any of my recently listening, so without further ado here’s this weeks SubMafia show from Italy.
Following on from last Fridays post here’s an Accordion container and DataAccordion control.
Massive thanks to both Luke Whittaker and Rob Bateman for two great talks last month. Both videos can be found in the presentations section.
This month David Kinross with an ‘Introduction to AlivePDF’ and following him, tag team Andrew Skinner & Tadhg McCarthy with a session on ‘Developing for Kids and Families’.

So here’s a spark AccordionLayout that can be used like a standard layout in spark. It’s a class that I’ve been thinking about for some time, means an accordion is a navigator and I’ve put a fair bit of work into spark navigators. I’ve also been meaning to make this post for some time but have been tweaking things and wanted to wait. There’s still changes to be made but I think it’s at a point where I can finally release it into the wild.
One of the main thinking point when it comes to the spark approach and an Accordion is how to handle the position and size of the ButtonBar that makes up part of an Accordion. I finally decided to pass a reference to the ButtonBar through to the AccordionLayout, this layout then takes over the measuring of the ButtonBar and the positioning of the Buttons that make up the ButtonBar.
Two of the most interesting and useful properties are layoutAllButtonBarBounds and minElementSize.
layoutAllButtonBarBounds when set to true means that the AccordionLayout takes control of the sizing and positioning of the ButtonBar itself, making it match the size and position of the ISelectableList.minElementSize can be used to make all the elements visible at the same time (note that you will lose the advantage of virtualization). After a couple of requests from people, the Tink Google Code lib is now duplicated over a GitHub.
Huge thanks to Shaun Smith for coming round and sorting this out for me.
Next up versioning, making sure there’s always a recent SWC to download and ensuring that it’s easy to compile.
