_gtkTextTagCBclick

Set the callback when the user press a mouse button on a part of text which has a particular tag. This is a "light" callback.

Définit un réflexe de click (bouton appuyé) sur une partion du texte sur lequel un tag a été apposé.

Type :

fun [ObjGtk fun [ObjGtk u0 S S I] u1 u0 S] ObjGtk

_textview_ : ObjGtk : any textview object already created.

_reflex_ : fun [ObjGtk u0 S S I] u1 : callback

• _reflex_textview_ : the same _textview_ object;
• _reflex_userparam_ : u0 : the same _userparam_;
• _reflex_tagname_ : S : the same _tagname_;
• _reflex_texte_ : S : the part of texte which the tag has been set (limit to 127 first characters);
• _reflex_button_ : I : the pressed button number (SGTK_MOUSE1, SGTK_MOUSE2, SGTK_MOUSE3, SGTK_MOUSE4, SGTK_MOUSE5 or 0 if unknown / other).

Return : u1 : your return.

_userparam_ : u0 : a parameter at your convenience.

_tagname_ : S : the name of the tag. The tag must be already created. If _tagname_ is equal at nil, then a click will call the callback from anywhere on the _textview_.

Return : ObjGtk : the same textview or nil if error (tag not created, object unknown, ...).
