Zero To Awesome: Using Webviewers For Data Display

Oh, how easy it is to back yourself into a corner!

Well, to be honest, you get to a point where you know you can [almost] always figure a way out. However, it can be a bit scary when you've chosen a data model and you find it won't fit your interface objectives.

In this Zero to Awesome series, I've chosen to store all contact related details in a dedicated table named Attributes. The advantages to this, include easier searching and a more flexible and optimized storage of data. The problem created is knowing how to extract what you want to display.

Webviewers to the rescue! Yes, this is not what you would expect to use webviewers for, but why not? When you simply need to display data, FileMaker doesn't much care about using a field versus a webviewer, it's simply getting drawn to the screen. Yes, there may be a small amount of overhead, but when you get to the point that your FileMaker application needs to scale you can address the issue then. Watch this video to learn more about using webviewers for some flexible options in data display!

Technique File error

Matt,

The technique file has "method" as a parameter in webview.address (I think you added it in the video), but the calc on the webviewer does not, so it comes up displaying "?". Removing it from the custom function or changing the order of the parameters fixes the issue.

By the way, it was a pleasure meeting you and playing drums for your RockBand at DevCon. We were miserable failures at the game, but it was fun.

Yeah, I did add it in the video. I'll change the download file. Thanks for letting me know and yeah, that was fun. They should have had a beginner's track for those who had never done it. :)

Flashing in Windows

.

I really like the idea of using the web viewer for data display. However, I feel like it isn't quite ready on the Windows side of things. On the Mac everything works great, but on Windows web viewers on the screen can greatly exaggerate the flashing that can be all so prevalent in Filemaker.

I don't know if it is the way Windows draws the screen or the way Filemaker draws the screen in Windows but my users already complain about screen flash, adding more web viewers definitely won't help the situation.

I guess I need to try and get my company to switch to Macs and then this would not be an issue, until then I hope Filemaker can once and for all reduce screen flashing under Windows.

control the layout of the webviewer elements?

I would not want to display the address info as shown in the video, but would rather have a more traditional layout of:

Address
City, State Zip
Country

I would also like to have labels for the data. In particular with addresses for some places outside of the US, it might not be clear what bit of data is what.

I don't know too much about HTML, but would it be possible to format the data like I have outlined and to include labels?
