Re: create and delete widget   
Hi Afif,
Please specify what do you mean by script: shell script or program code?

There are two basic ways to create a widget: using Photon Application Builder (PhAB) or  using c/c++ code in your 
program.

For PhAB see:
http://www.qnx.com/developers/docs/6.5.0/index.jsp?topic=%2Fcom.qnx.doc.photon_prog_guide%2Fwidgets.html&cp=17_0_6

For code see:
http://www.qnx.com/developers/docs/6.5.0/index.jsp?topic=%2Fcom.qnx.doc.photon_prog_guide%2Fwgt_code.html&cp=17_0_12


Best regards,
Fedor

I don't understand how to use the code, I want to create an image as label and the picture is in my directory.

Re: create and delete widget   
You can use PxLoadImage() and then PtSetResource() with Pt_ARG_LABEL_IMAGE flag.
E.g.
PhImage_t *my_image;
my_image = PxLoadImage(“/home/my_pict.jpg”, NULL);
PtSetResource( ABW_my_label, Pt_ARG_LABEL_IMAGE, my_image, 0 );


For more information please read following help topics about PtLabel and PhImage_t:
http://www.qnx.com/developers/docs/6.5.0/index.jsp?topic=%2Fcom.qnx.doc.photon_widget_ref%2Fptlabel.html&cp=17_2_2_32
and

Best regards,
Fedor

Re: create and delete widget   
my script is like this :

 my_image= PxLoadImage("/home/PSR.jpg",NULL);
 my_label=PtCreateWidget(PtLabel,Pt_NO_PARENT,1,args);
 PtSetResource( ABW_my_label, Pt_ARG_LABEL_IMAGE, my_image, 0 );

but it's error because my_label is not define. what should I do? 

Thank you.

PtLabbel requires parent widget.

You have to include phexlib library in your common.mk.
E.g.
LIBS += phexlib
