Dynamic Navigation Pane Push Pages

Posted on by

That is somewhat of a tongue twister and it all came about because of a question on a forum.  The CrackBerry.com forums has a section for new developers, which is always a nice thing to have.  The poster is apparently trying to create an app to serve up radio stations (I think) and he wants to provide a Page for each station and also provide the list of stations through an xml file.  On the main page, he wants to display a ListView with links to the secondary Pages. Normally, I would just create ComponentDefinition for each Page and then Continue reading Dynamic Navigation Pane Push Pages→

Dynamic Context Menu and the Period

Posted on by

While I am still slowly working on my Meetup for BlackBerry 10 app, I decided to do a “quick” app that handles shopping lists.  This was suggested by a user on the Crackberry.com Forum.  He wanted a basic shopping list that he could easily move regularly bought items to a buy list and check of the items when he purchased them.  He also wanted to be able to move items on the list, but that will be another post (if I get it working). I decide to keep things really easy and only do a single page for the entire Continue reading Dynamic Context Menu and the Period→

Easy pinch zoom for ImageView

As part of my Meetup for BlackBerry 10 app, I provide the photo albums for the user’s groups.  With the list of albums, the user can drill down to see a list of the images and then click on the individual image. The image is loaded into the ImageView component from a url on Meetup.com.  Due the obvious screen size difference between the files upload and a phone, the image is re-sized to fit on the available screen.  Regardless if the screen is the 1:1 Q5/10 or the 16:8/9 Z10/30, the user will need to zoom in on the picture Continue reading Easy pinch zoom for ImageView→

Better way of adding a Sheet

I am making some more updates to my Meetup for BlackBerry 10 app and wanted to add a page for Settings, which is accessible from the pull down app menu.   Screens in Cascades are either a Page or Sheet contained by themselves or in a Tab or Navigation panes.  My application is already setup using a TabbedPane, so in order to add something that isn’t a Tab, I need to display a Sheet.  Previously, I added a sheet to a photo album page to show a single photo.  After you define the sheet on the Page, to display it, you Continue reading Better way of adding a Sheet→

My first BlackBerry 10 app

Posted on by — No Comments ↓

I just updated my first BlackBerry 10 application; Meetup for BlackBerry 10. I was attempting to get the app released by a deadline in order to win a free Z10 in Red.  The offer was to be one of the first 500 developers to build an app and then get it certified as Built for BlackBerry in a certain time frame.   Well, I didn’t get it submitted in time, because there is a big delay between getting your app submitted and getting it reviewed; then apparently there is a delay for getting Built for BlackBerry certified.  Because I rushed Continue reading My first BlackBerry 10 app→

Privacy Policy, Change Log and the App Menu Definition

Posted on by — No Comments ↓

In an attempt to get a free Red Z10, I tried to get my Meetup application finished by a drop dead date and submitted to Built for BlackBerry by Oct. 21st.  That didn’t work, but the app is available, in probably more of a beta state.  I’m working on the fixes when I can.  As part of the Built for BlackBerry requirements, you have to provide a link to a Privacy Policy from your application.  From the developer forums, there were two ways to link to the Privacy Policy.  One method seemed to be a link from the vendor portal, Continue reading Privacy Policy, Change Log and the App Menu Definition→
