I have seen the Codename One Video on how to create a Codename One Hamburger Side Menu using Commands.
I have been trying to see if I can do that on a button click instead (my forms have title bars turned off, i use a border layout and create my own title bar by placing it in the North), with probably another from as the side menu. I would like to have an image and then a custom menu display on my Side Menu instead of the regular Codename One buttons.
Has anyone tried something similar?
I suggest you take a look at the Toolbar class which is more powerful and would probably alleviate the need to override the title area:

You can't set a form at the side menu but you can add arbitrary components into it which should be enough. Again the Toolbar API makes this rather simple.

I want to display HTML in my forms. The problem is I have to use a Boxlayout to place my components. So when I put a WebBrowser I'll have some height and scroll issues. I get the HTML I want to display from a webservice. The length of the content is variable. I just want to display a part of this response. Here is what I already have:
The webBrowser is below the edit button and ends near the LBL_LIB_NOM label.
As you can see the webBrowser is way too high and I can't scroll the Form when I click over the WebBrowser. In this example I would like to reduce the size of the WebBrowser so we can only see the Title. I also would like if possible to scroll my form when I click on the WebBrowser since I don't want the WebBrowser to scroll.
I have tried a few things to solve my issue:
I tried to override the calcPreferredSize method.
I revalidate my form and my webbrowser.
I resized it's container using the deprecated setPreferedSize method.
In that case the container is well sized but the the WebBrowser displays
above the other components.
The usual answer I have seen in other posts is to put the WebBrowser in a BorderLayout but I can't do that.
So here is my question: Is there any other component I can use to display one HTML line ? Or is there a way to make a webBrowser work properly in a boxLayout ? Do I have to write my own HTML renderer ?
I'm guessing you want box layout so you can scroll... This is problematic.
Web views generally expect to scroll themselves and this is common in native widgets which handle their own events and thus scrolling. It's hard for our code to know when your swipe is intended for us or to the underlying native widget and it's harder still to do this in a consistently portable way.
There are 3 options:
Use only Codename One code
Use a border layout or similar layout
Use the web browser for the entire UI of this form
If you want to take the first option this article might be useful as a starting point.
I m working on my mobile apps using codename1 and i found that after adding an autocomplete textfield to any form, every other component disapears along with tabs behind a white container.
It sounds like you are using a scrollable FlowLayout (which is the default layout manager) and some nesting behavior goes bad.
Another guess is that you add everything into the layered pane which is a HUGE MISTAKE, you should add everything to the form directly or content pane.
Using the designer only:
Is it possible to display a clickable link (to a web url) in a label or in another suitable component of Codename One? Thanks!
Use a button, give it a different UIID and style it to look like a link.
I am working on codenameone, and trying to make the first UI.
A basic UI with a title and two buttons on two sides of the "title" to go to two different pages.
I was trying to do that with "Form" component but then it only gives one button by default, which is just taking me to the previous screen.
Not sure how to do this, any link or tip is a nice help.
thanks
Use addCommand(new Command("X")) or in the GUI builder just click the commands property in the form. It will automatically use the menu for Android.
The back button is added automatically for iOS apps for back navigation which you will probably need. You can disable it in the state machine code and have room for two commands in the title.
So I created a layout in Expression Blend 4 for my Silverlight application. Now I need to create a simple navigation to navigate between pages. I have a canvas control in the layout (MainPage.xaml) and I would like the navigation buttons to just change the content of the canvas.
So if a user clicks on a navigation button for Page1.xaml, the Page1's content will be loaded into the canvas.
Could anybody give me an example how to do it? I tried using the MenuItem control but I could not understand how to use it. Now I have just used buttons but I don't know how to make a navigation from them.
I would love to be wrong about this but Im pretty sure, Blend 2,3,4 (the ones I have used)are just like windows form development your controls are not active until you actually build and run the application.
Sorry
Edit
To answer your comment the menuItem is a simple control that has been predefined like a button or link. The main idea with blend is to give developers and designers the ability to customize the look and feel of control layout in a similar way html uses CSS and javascript.
Try using "Hyperlink Buttons" for your menu and display the content in a "Frame" control.
