Code implementation for GUI
Carbider | 25 October, 2007 09:28
At post: Assembling GUI set reflecting future BluSPAN functionality I have shown the GUI that will take place at BluSPAN application. Now I will tell you about some difficulties I’ve faced during this.
Since the “Status” menu-item in Options menu was created, I wanted it to perform Query List popup for user can select his status. This was done with “List Single Query Dialog” component.
After lots of research, and looking at examples, I knew that after this component is placed onto designer, the “RunListQuery1L();” is generated.
So I’ve implemented the “selected” event with call to it:
… ::HandleStatusMenuItemSelectedL( TInt aCommand )
{
// Run the Single Query list Of Status
int resultIndex = RunListQuery1L();
return ETrue;
}
And it worked.

Creating new UI design in current application
To allow user customize the “USER”, “PAN” and other settings I had to create new designs with Settings Lists.
To do that, just right click on a project, and select:
“New->Other->Symbian OS->S60 UI Design”
Select “Setting Item List” type of interface. Write appropriate name. For example: “SettingsPAN” and click Finish. After that you can start customizing new UI design by arranging the components.
Once a User Settings design, was created, I’ve put “Text Editor” component there for user’s nickname . After Build the error occurred:
“object 'KEdit1MaxLength' redefined”.
“object 'KEdit1MaxLength' redefined”.
But that was not so definitely, because I’ve made a lot of Designs to that time, and I’ve got a lot of similar errors. After examination it was clear that UI Designer generated the same code for newer “Text Editor” as it was for main application’s design (there was “Text Editor” too). Is it so clear?
But I’ve changed Component’s name from “edit1” to “User_edit1”. The errors stepped back.
At current stage I have a lot of Design screens with BluSPAN settings. But I don’t know how to switch between them. When new Design is created, the remark is shown: “Use View Switching: Avkon View-Switching architecture uses the View Server to activate your designs”. But I did find how to use it.
Picture 2 – The questions is: How to switch UI designs in application?
Did anybody face this challenge?
