Scol » Lib2D GTK

h1. Callback

* _gtkButtonCB

Define a Scol callback to any button. One function to define differents callbacks. So, set the flag correctly ;-)

You can call it several times to a same object.

h3. Prototype :

> fun [ObjGtkWidget u1 u0 I] ObjGtkWidget

>> * Button : ObjGtkWidget : any button already created

>> * Reflex : u1 : the prototype of your Scol callback (see flag below)

>> * UserParameter : u0 : any parameter at your convenience

>> * flag : I : a flag :

>>> * SCOL_GTK_BUTTON_CB_CLICKED : the button has been clicked

>>> The type of the callback should be fun [ObjGtkWidget u0] u1

>>> * SCOL_GTK_BUTTON_CB_TOGGLED : the state of the button has changed

>>> The type of the callback should be fun [ObjGtkWidget u0 I] u1

>>> The supplemental parameter is the current state : 1 : active / checked, 0 : inactive / unchecked

>>> * SCOL_GTK_BUTTON_CB_LINKED : the button with a link has been activated. GTK+ 3.0 or + only. Otherwise, it is ignored.

>>> The type of the callback should be fun [ObjGtkWidget u0 S] u1

>>> The supplemental parameter is the url.

>>>>> *WARNING* : you should respect these prototypes to yours functions !

>> * +*Return*+ : ObjGtkWidget : the same object
