The way to E6/A1200 Native EZX Application

[eakrin]

I don't know much about debugging and QT/C++ object. but I done ZApplication.h by rewrite ZApplication class. with a samr7 zapplication.h template from dev-ezx and from qapplicaion.h from qt2.3 embended soruce code.

ZApplication is inherited from QApplication

many class in libezxbase.so inherited from common qt object. we need to rewrite our own header file to use them in C++ complier.

after that I try to compile application with header file to test it.

but some function motorola extend from common qt-embendded. so we need to find out which each parameter is?


I think. for easy development in the future. we need our own widgets. so we don't need to wait for motorola official SDK anymore. we maintain it and adapt it when a new model came out. only special phone API that we need to hack from libraries.

what i think is
1. wrapper all Widgets by qt-2.3 source code + donga wrapper technic. we got to create native application with GUI.

2. hacking all phone API from libraries like phone call, skin and iconres, bluetooth, email, sms, etc. I think they doesn't inherited from qt. this is very difficult path to success it.

after this we 'll not need motorola EZX SDK anymore.

How do anyone think about this idea?

About wrapping:
Here is a method of wrapping QT 4 apps on E680/A780 phones. Now I'm working on my environment (setting up cygwin etc). After that i'm planning to make this wrapper work on E6.
I think that the main challenge is to develop an easy way to port some kind of apps (like QT4) to our phones.

@eakrin
Agreed, but be best job if we can wrap the QWidget first. I mean if we can generate the QWidget header (qwidget.h) for work fine on our app first.

@lavelas
Do you mean that run QT4 on seperate environment of EZX like OPIE for EZX ?
For my target, i need the real native EZX base app runs on the same environment of the other EZX apps (Yess, it very very difficult ).

@lavelas
eXMMS for A1200/E6 using qte-2.3.10 as GUI library and the native qapplication and qwidget as event catcher only.

[lavelas]

@donga, it's difficult and there will be no easy way to port already written apps (like qte) to the EZX platform.

@blackhawk, is the original source code have been developed using qte-2.3.10? If so - your event catcher is almost that wrapper i told except it is for qte-2.3.10 (not for qte4).

[blackhawk]

eXMMS can compiled and running using qte-2.3.6, E680i/A780 ezx library, qte-2.3.10, and qt-3.x.x on Fedora desktop

At last I founded my time to make my cygwin environment work. Donga, you've made a great job. One thing that bothering me: why can't we derive classes from ZMainWidget? There must be a reason of this seg fault.

Also I've made some investigation of libezxappbase.so and found some functions that are not described at header files. I've describe this functions at my local copy of zapplication.h, but I'm wondering where to publish this results? Is there a place where we can share our workaround of dev-ezx? If not, maybe we can create it ourselves?

great job!
but how to use the class QEListBoxItem ?
my code:
void QEAppTemplate::setupContent()
{
QEUTIL_ListBox *list = new QEUTIL_ListBox ("ListBox", contentWidget ());
((QScrollView*)contentWidget())->addChild(list->widget());

QEListBoxItem *item1 = new QEListBoxItem (0, "ltem1");
list->show ();
}

the program seg fault when new QEListBoxItem, appreciate for replay, thx a lot.

I modified my code:
void QEAppTemplate::setupContent()
{
QEUTIL_ListBox *list = new QEUTIL_ListBox ("ListBox", contentWidget ());
((QScrollView*)contentWidget())->addChild(list->widget());

item1 = new QEListBoxItem (list->widget (), "list item1", 0, TRUE);
list->insertItem (item1);

item2 = new QEListBoxItem (list->widget (), "list item2", 0, TRUE);
list->insertItem (item2);
list->show ();
}
when I delete the statment "list->insertItem (item2)", it works,but when I add this statment, the program still crashed, I can only add one item into the listbox?

So... can anyone port EzxEmu to a1200/E6 now ?
