Type :

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

_textview_ : ObjGtk : any textview object already created.

_reflex_ : fun [ObjGtk u0 S S I I I I I I I [S I] I I I] u1 u0 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);
• _reflex_typeevent_ : I : it should be the same _typeevent_;
• _reflex_x_ : I : the x coordinate, relative of the textview;
• _reflex_y_ : I : the y coordinate, relative of the textview;
• _reflex_axes : I : 0 if the device is a mouse, otherwise 1;
• reflex_mask_ : I : mask (as CTRL, ALT,....). It can be any combination of these flags : SGTK_MASK_SHIFT, SGTK_MASK_LOCK (caps lock), SGTK_MASK_CTRL, SGTK_MASK_MOD1, SGTK_MASK_MOD2, SGTK_MASK_MOD3, SGTK_MASK_MOD4, S GTK_MASK_MOD5, SGTK_MASK_SUPER, SGTK_MASK_HYPER, SGTK_MASK_META or 0 if other / unknown;
• _reflex_time_ I : the time of the event in milliseconds;
• _reflex_device_ : [S I] : a tuple with the name of the pointer (for example the name of the pen (known of the Operating System) and the type of this device : SGTK_SOURCE_MOUSE, SGTK_SOURCE_PEN, SGTK_SOURCE_ERASER, SGTK_SOURCE_CURSOR or 0 if undefined / other;
• _reflex_xroot_ : I : the x coordinate, relative of the screen;
• _reflex_yroot_ : I : the y coordinate, relative of the screen;
• _reflex_position_ : I : the position of the clicked character in the textview.

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_.

_typeevent_ : I : the type of the event to call the callback : SGTK_PRESSED (the user press the mouse button), SGTK_2PRESSED (the user has double-clicked), SGTK_3PRESSED (the user has triple-clicked) or SGTK_RELEASED (the mouse button is released). Another value don't set the callback.

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