The algorithm of Figure 3-12 illustrates the reordering of blocks, but you don t need to do that. It s a user implementation detail. This recipe and the sizing algorithm focus on the awareness of giving the HTML page feedback that a table cell now has room for one, two, or three columns of content. How that content is displayed depends on the HTML page and is beyond the scope of the sizing algorithm. Getting back to the source code of the calling HTML page, the function setContentCallback is called after calling setCharacteristics. The purpose of the function setContentCallback is to define a user callback that is updated with the new information of how many user-restricted columns can fit in a cell. In the example, the client code displays the parameters in the table cell. To reproportion the table, you call the method update. The first time update is called, it is from the body onload event. The body onload event is fired only once and won t be called again if the client resizes the client browser. To have the update method called whenever the browser is resized, the window.onresize event is assigned. In the example, you assign window.onresize to the function updateClientArea, which makes a single method call to flexbox.update, which in turn updates the proportions of the table. Now that the theory of the sizing algorithm has been explained from the abstract level, let s discuss the details of the sizing algorithm. The following code shows the complete implementation of the sizing algorithm. Note that the sizing algorithm is a custom implementation, and you might choose a different strategy in your own situation: function FlexBox(parentIdentifier) { if (typeof(parentIdentifier) == "string") { this.parentIdentifier = document.getElementById(parentIdentifier); } else {

Downloading the proper simulator files for the devices you plan to run on is essential, because different types of devices will have different screen sizes and input modes. Even if you have two devices with the same model number, they will behave differently depending on what software version they are running. Simulators are not just important for testing on the computer, though. They also contain essential information for debugging on the actual device. If you have the physical device you will be using, find the device software version by visiting Options, then About. You will be looking for a version that matches all parts of the version number. For example, if your device has version 4.5.0.81, only use 4.5.0.81, not another version that starts with 4.5.0. You can download simulator packs from the BlackBerry web site. The exact location will change, so your best bet is to visit the Developers page and look around for the BlackBerry Smartphone Simulators. You will see many, many choices. Pick the one that matches your exact version number and device model and, if applicable, carrier. You ll need to click through another web

own versions of a binary in place of a system binary. For instance, Mr. Joebob Poweruser always likes to have the latest, greatest version of Perl on his system, dutifully installed at /usr/local/bin/perl. However, with a default PATH variable, when Joebob runs the command perl, he will be treated to our localization s binary stored at /usr/bin/perl. To change this, Joebob will want to modify his ~/.bash profile file, adding the line

export PATH="/usr/local/bin:$PATH"

form get used to it, as there is no way to save your information. Download the simulator file, then run it to install. You can install to any directory you like. To switch to using a new simulator in Eclipse, follow these steps, and restart Eclipse if you are ever prompted to do so. 1. 2. 3. Click the Window menu, then Preferences. Expand the BlackBerry JDE menu and select Installed Components. From the drop-down list, select the component pack that corresponds to your device version. For example, pick 4.5 for a device with version 4.5.0.81. If you don t see your component pack listed, install it following the instructions in the section titled Plugged In earlier in this chapter. Click the MDS Simulator option and navigate to the MDS directory that matches the component pack from Step 3. Note: The directory will be located under your Eclipse install folder. The path should look something like eclipse\plugins\net.rim.eide.componentpack4.x.x_4.6.x.xx\ components\MDS. 5. 6. 7. 8. 9. Click OK. If you already have a project in Eclipse, you will be prompted to rebuild it. Click Run, then Debug Configurations. Create a new BlackBerry Simulator configuration. Click the Simulator tab. From the Profile drop-down, select the item that corresponds to the simulator you installed.
