* @since 1.8.0
|
||||
* Simple Edje example illustrating the edje_codegen usage.
|
||||
*
|
||||
* edje_codegen is a tool that generates code to acessing the parts and programs
|
||||
* with the keyword "api" of a specified group. This tool make easier working
|
||||
* with edje avoiding common errors caused by typos when acessing the parts
|
||||
* and/or programs.
|
||||
*
|
||||
* To use the edje_codegen:
|
||||
* edje_codegen --prefix <myapp_myobj> <input.edj> <a_group> <source.c> <header.h>
|
||||
*
|
||||
* In case of this example:
|
||||
* edje_codegen --prefix=codegen_example codegen.edj group_example \
|
||||
codegen_example_generated.c codegen_example_generated.h
|
||||
*
|
||||
* @verbatim
|
||||
* edje_cc codegen.edc && edje_codegen --prefix=codegen_example codegen.edj \
|
||||
* example_group codegen_example_generated.c codegen_example_generated.h
|
||||
* gcc -c codegen_example_generated.c `pkg-config --libs --cflags ecore-evas edje`
|
||||
* gcc -o edje-codegen-example codegen_example_generated.o \
|
||||
* edje-codegen-example.c `pkg-config --libs --cflags ecore-evas edje`
|
||||
* @endverbatim
