8 - Using Sizers in Boa Constructor [ID:1045] (8/9)

in series: Introduction to Boa Constructor

video tutorial by cmpython, added 02/09

(Showmedo is undergoing major changes. To report any problems viewing the videos please email us and include browser and OS specifics. Cheers - Kyran.)

Sizers are the way to go for layout of widgets in wxPython, but learning how to use them can be difficult. This video shows how to use the Designer, Inspector, and Palette to create a very simple layout using a boxsizer and flexgrid sizer.

Please note that this is very introductory, just to give the basic idea, and there is much more than can be shown, but this is an introductory series. For example, flexgrid sizers can be tweaked from within Boa for more complex layouts (really, in the simple example shown here, I could have used another boxsizer instead).

Also note: The proportion value of 1 is described as meaning "take up 100% of the available space". While that is true for this simple case, when there is more than one widget being sized that has a non-zero proportion value, the sizer will divide the space proportionally (e.g. if one is set to 1 and another set to 3, the first will take up 1/3 the space of the second).

I may at some point get around to doing a thorough go-through of sizers in Boa in another, more advanced video.

Good Stuff

Keep up the good work

I liked very much your presentation. I use FoxPro for about 15 years but I'm seriously thinking about Python as a new solution. I use FoxPro with PostgreSql. Some times it's necessary to see apps working step by step to get courage to change.

Thanks. You actually made Sizers look easy!!

34. knizqopbkhu Thu, 11 Feb 2010 19:29

This series has helped me get a jump start in Python and wxWidgets. As the wxWidgets documentation isn't incredibly strong - this is not only a helpful - but also an essential resource.

Thanks for making this available - it is just fabulous.

33. retro snapback hats Mon, 18 Jan 2010 09:37

Excellent tutorial keep up the good work!!!

32. anonymous Fri, 27 Nov 2009 08:23

Great. Many thanks.

31. anonymous Mon, 23 Nov 2009 09:47

Despite my best efforts, I could not understand sizers until I saw this video!!..

30. anonymous Tue, 03 Nov 2009 07:17


The sizers in Boa was a little bit tricky for me and your tutorial is very clear and useful.

Great job, thanks

29. anonymous Mon, 26 Oct 2009 10:58

Very helpful videos. Thanks.

28. anonymous Sat, 17 Oct 2009 09:18

Great tutorial about excellent IDE RAD for Python! Thanks. It helps a lot.

27. anonymous Sun, 11 Oct 2009 10:32

Thank you these tutorials were very useful

26. anonymous Mon, 28 Sep 2009 09:01

This was a great tutorial, and should save beginners hours trying to learn to use sizers!!

25. anonymous Sun, 20 Sep 2009 03:09

Thank you very much for the videos.

24. anonymous Sun, 20 Sep 2009 03:09

Thank you very much for the videos.

Very nicely done. I've done some wxPython myself, even used sizers, but I've not used Boa Constructor yet, so that's cool to see. You can see one of my wxPython apps in my Python Network Programming Series on ShowMeDo.

I'm also quite impressed with your delivery. Did you use a script and did you record the audio while doing the video, or did you record it separately? There has been some interesting discussion about audio and the workflow of producing screencasts in the Google group that Ian started, we'd love to hear your screencast production secrets.

22. anonymous Fri, 04 Sep 2009 03:49

Excellent presentation; saved me hours of frustration. Thank you very much.

21. anonymous Sat, 29 Aug 2009 15:12


I'm just starting so it seemed a little fast. I'll see if I can find your earlier videos and start at the beginning.

20. anonymous Thu, 20 Aug 2009 09:49

Really good work.

Thanks I learned a lot.

19. anonymous Tue, 04 Aug 2009 06:08

Very Useful and inspiring to get going!

18. anonymous Wed, 22 Jul 2009 08:06

OH, this video is great

tanks a lot

17. anonymous Mon, 20 Jul 2009 19:37

I think the video is very good.

It shows how to use the Sizer and how it's working


16. anonymous Mon, 20 Jul 2009 11:50

Very refreshing, I always forget how to use sizers on Boa after a while.


15. anonymous Mon, 13 Jul 2009 04:09

Thanks for sharing this clear and helpful video.

I appreciate presenting things in such a simple way.



14. anonymous Fri, 10 Jul 2009 10:03

Very good introduction to sizers!

13. anonymous Wed, 24 Jun 2009 01:12

thx again

12. anonymous Thu, 11 Jun 2009 14:33

NOW he introduces the creation of sizers. I can't figure out why he talked about manipulating sizers in an earlier video.

This video is quite fast-paced. I follow along by recreating everything from the video in Boa. I'll have to replay the video another once or twice to fully absorb the material.

I learned way more in the last few hours than from all the half-hearted written on-line tutorials in the past week.

It would have been great he did a bunch more video tutorials on Boa. Great work.

11. anonymous Thu, 28 May 2009 04:33

This video is very helpful.

With only a quarter of my time I'm able to draw a gui with sizers with boa.

You get my vote.

Thanks a lot.

10. anonymous Tue, 05 May 2009 03:36

very good and followable.

Thank you very much!

Shabu! Shabu!

too good..very explanatory..just too good

4. anonymous Tue, 14 Apr 2009 11:25

Great Videos. I did not knew that boa has so many features.

3. anonymous Sat, 11 Apr 2009 08:54

well done video, I think you should do more videos about boa constructor.

2. anonymous Wed, 08 Apr 2009 13:56

Nice tutorials!

Great tutorial on Boa. Thanks for putting time and effort into this!

Educating the Open-source Community With Showmedo

Although as important as the software it supports, education and documentation are relatively neglected in the Open-source world. Coders love to code, and explaining how best to use or improve the software tends to be deferred or even sidelined.

At Showmedo we believe the community can play a vital role here and also say thanks for the tools and software that make our lives easier. If you have a piece of software you love or a programming langugage you are enthusiastic about, why not make a screencast showing others how to use it? All the stuff you wish you'd been told, the tips, tricks, insights that would have saved you time and frustration.

Screencasting is easier than you think, and we're happy to help you. You can emailus for advice or just use some of the how-to screencasts on the site. This screencasting learning-pathis a good place to start.

Kudos and Thanks for cmpython
