[ZMultiLineEdit] EZX Programming for dummy by dummy A1200, E6

[eakrin]

after test with ZPushButton in http://www.motorolafans.com/forums/showthread.php?p=132847#post132847

Now I try another widget. here is a memCheck application. main widget is ZMultiLineEdit. application doing an easy job by execute command cat /proc/meminfo and dispaly result in ZMultiLineEdit.

ZMultiLineEdit is a text box that can have 1 or more lines. and it can expandable in both size.

you can create ZMultiLineEdit by

memStatus = new ZMultiLineEdit( this, false, 12 );

this = parent widget. can be content widget, QVBox, QBox. but can not create ZMultiLineEdit on ZScrollView it cause a segmentation fault.
false = ezx style. I found no different between true and false. report me If you found it.
12 = number of lines.

After create it ZMultiLineEdit need to config many properties such as

setWordWrap for define wraping text.
setSizePolicy for define expanding in horizontal and vertical when text length is out of it's area.
setReadOnly to make it read only but can copy text inside it.
setMaxLength for define number of characters for user input.

and we can define filter for input by

QRegExp mFilter = QRegExp("[^0-9]");
mPhoneNumberEdit->setFilter(mFilter);

see QRegExp for more detail.

Here is a full source code of memCheck demo.

int main( int argc, char** argv )

    ZApplication app( argc, argv );
    MemCheck *mw = new MemCheck();

    app.showMainWidget(mw);
    return app.exec();

and you can set startup keyboard by setInputMethods.

setInputMethods( mPhoneNumberEdit, IMID_NUMBER_KB, 0, 0 );

IMID_NUMBER_KB is a keyboard constant id defined in ZIMethod.h. IMID_NUMBER_KB is Quuid not a string. I tested only number keyboard. didn't test with symbol, thai, china board. And There have no another language keyboard id in ZIMethod.h may be we can use them from *.kdb in EMEA_LP.

And need to replace ZMainWidget.h with my update from this post for setInputMethod.

thanks for blackhawk about setInputMethods.

To prevent ZScrollView raising seg. fault, you have to set the child widget minimum size.

ZScrollView *sv = new ZScrollView(this);
setContentWidget(sv);

ZMultiLineEdit *le = new ZMultiLineEdit(sv->viewport(), TRUE, 10);
le->setMinimumWidth(ZGloball::getSubContentR().width());
sv->addChild(0, 0, TRUE);

Using above code, you will have a ZMultiLineEdit with EZX style You have to set the ZMainWidget's edit mode argument to TRUE, to make the ZScrollView have auto resizing ability (when the virtual keyboard invoke). ZScrollView also can to manage the child widget size and layout but not do the job for now, maybe because we have incomplete header for it.

Now I can compile EditorE source code without any modification (except the environment set and a bunch of soft link to foxe6's EZX headers. Yes, I keep blackhawk's SDK standard). The file browser not working as expected but this application now running on A1200 I have to use different libezxappbase Must I have to flash my Ming to different firmware?

[eakrin]

@blackhawk.
what is your f/w. ? Look like you use a Monsterpack or Hybrid f/w. I 'll test A1200i, A1200r, A1200e library later. But I think It should be the same library in A1200, i, r ,e, and E6. I use only E6's libraries and make a symbolic link to a1200. all my apps worked in both A1200 and e6. I think you have the same problem as ustrucx. he flash his phone to standard f/w and everything work fine with foxe6's sdk. and be careful for A1200 f/w track.

because I think now I found the source of segmentation fault error from *.h file. Need to test it a little to be sure. Then after that we should have many header files as we need. LOL.

cheer!

I've tried yan0 or foxe6's SDK for many times on my A1200E, but always fail when setup a ZMultiLineEdit. Now, I find the way from xptools and MFiles:

First, replace the libezxappbase.so.* with libezxappbase.so.1 from these packages. Compile the application with foxe6's header files. Coy libezxappbase.so.1 to your SD (eg: /mmc/mmca1/lib/ ). When launch the executable, set the env like this:

#!/bin/sh
. /home/native/.profile # apply QT exec env
export LD_LIBRARY_PATH=/mmc/mmca1/lib:＄LD_LIBRARY_PATH

exec /where/your/app/is

This my first time to make a simple application with ZMultiLineEdit to run on my A1200E from source!

@redice
Congratulations! I have talking about this problem above. This is the reason why MFile author can use EditorE source to build Edit (text editor binary inside MFile package) but we still have a problem: ZScrollView can not manage the child widget properly. That's why Edit file browser not work as expected. I have an updated EditorE source, the file browser now look more native (using UTIL_ListBox) but far away from my computer for now and have no the source copy to upload it here

@redice
Since we have a same problem, is your firmware R532_G_11.00.59P like my mine?

I've also tried using ZMultiLineEdit on my a1200e, with foxe6's SDK I got seg. faults, but eug from motofan.ru told me how to correct the SDK:
compare these chunks of code

public:

    ZMultiLineEdit( QWidget *parent=0, const char *name=0);

    /**
     * Constructor of ZMultiLineEdit
     *
     * @param EZXStyle if false, the class is almost the samewith qmultilineedit.
     * if true ezx-special functions will be suported.
     *
     * @param lines the default lines the ZMultiLineEdit has
     */
    ZMultiLineEdit( QWidget *parent,bool EZXStyle,int lines = 1,const char *name=0 );

    virtual ~ZMultiLineEdit();

This one is in foxe6's SDK

public:
  
    char buf[2048];

    ZMultiLineEdit( QWidget *parent=0, const char *name=0, bool unk=true );

    /**
     * Constructor of ZMultiLineEdit
     *
     * @param EZXStyle if false, the class is almost the samewith qmultilineedit.
     * if true ezx-special functions will be suported.
     *
     * @param lines the default lines the ZMultiLineEdit has
     */
    ZMultiLineEdit( QWidget *parent,bool EZXStyle,int lines = 1,const char *name=0, bool unk=true );

    virtual ~ZMultiLineEdit();

And this one is correct and works with libezxappbase from a1200e

so there's no need for library from e6

[redice]

@redice
Since we have a same problem, is your firmware R532_G_11.00.59P like my mine?

My firmware is R541_G_11.50.34P.

[blackhawk]

@borman
To compile an application that using ZMultiLineEdit (EditorE for an example), my R532_G_11.00.59P A1200's libezxappbase library need boolean argument in ZMultiLineEdit costructor but it raise segmentation fault at runtime. My English not good enough to explain, but we are not talking about that E6's libezxappbase is the correct library for this problem.

@redice
Different firmware but have a same problem
