+ *
* Whats the minimum amount of work you need to do to create your own EWL
* widget? Just want something you can build on but dont know where to start?
- *
+ *
* Well, hopefully this should give you the base for starting your widget.
* Assuming you're creating a widget called My_Widget, the EWL convention is to
* have a my_widget.c and my_widget.h files. There are only a couple things you
* need to implement to get a working widget.
- *
+ *
* First, my_widget.h.
- *
+ *
* @code
* #ifndef MY_WIDGET_H
* #define MY_WIDGET_H
- *
+ *
* #include <Ewl.h>
- *
+ *
* #define MY_WIDGET(w) ((My_Widget *)w)
* #define MY_WIDGET_TYPE "my_widget"
- *
+ *
* typedef struct My_Widget My_Widget;
* struct My_Widget
* {
* Ewl_Widget widget;
* };
- *
+ *
* Ewl_Widget *my_widget_new(void);
* int my_widget_init(My_Widget *w);
- *
+ *
* #endif
* @endcode
- *
+ *
* That wasn't so bad. What have we got? Well, the MY_WIDGET(w) define gives us
* a simple macro to cast other widgets to our widget. The second define,
* MY_WIDGET_TYPE, is a simple macro containing the type name of the widget.
* Well use that a bit later (and in any type checking we add to our widget.)
- *
+ *
* We then create the widget structure. In this case were inheriting from
* Ewl_Widget so its the first item in our struct (and not a pointer, thats
* important). This is how EWLs inhertiance works. The widget you're inheriting
* from is the first item in the struct and not a pointer. You will now be able
* to call any of the methods of the inherited class on the new class.
- *
+ *
* We then declare two methods. The convention in EWL is that the _new()
* function always takes no parameters (void). There is also always a _init()
* function that takes the widget as its only parameter and returns an int, if
* the initialization succeeded or failed.
- *
+ *
* With that out of the way, lets take a look at my_widget.c.
- *
+ *
* @code
* #include "my_widget.h"
- *
+ *
* Ewl_Widget *
* my_widget_new(void)
* {
* Ewl_Widget *w;
- *
+ *
* w = calloc(1, sizeof(My_Widget)));
* if (!w) return NULL;
- *
+ *
* if (!my_widget_init(MY_WIDGET(w)))
* {
* free(w);
@@ -81,35 +81,35 @@

* my_widget_init(My_Widget *w)

* }
* @endcode
- *
+ *
* Thats pretty simple. We create a new widget, initialize it and thats about
* it. In my_widget_init() we make sure we call ewl_widget_init() as thats the
* widget we are inheriting from and we then set our inheritance and appearance
* strings (notice the use of our type define from earlier).
- *
+ *
* With that you've got a simple widget. It doesn't do much, but it exists.
* Build on as you will.
