== Tutorial - Add a bool ==

; This is short tutorial, how to add a bool property to user_preference.

; I dont know how to setup patches with the build i use.
; I write fake patches and edit the source code directly.

; This is the kind of property you are going to add.

[[File:K_bool_00.PNG]]

; To do this we need patch three files.
: blender\source\blender\makesdna\DNA_userdef_types.h
: blender\source\blender\makesrna\intern\rna_userdef.c
: blender\release\scripts\startup\bl_ui\space_userpref.py

== DNA ==

; DNA, struct DNA, is where the blender data is defined.
; There are different types, enums, structs (which memory usually allocates), etcetra.

; Open blender\source\blender\makesdna\DNA_userdef_types.h.
; Look for the, eUserpref_UI_Flag, and eUserpref_UI_Flag2 enums.

; The max used in this list is 32.
; Add a new one to the bottom of eUserpref_UI_Flag2. Or 3 if exist.

<pre>
Index: source/blender/makesdna/DNA_userdef_types.h
===================================================================
- USER_TRACKPAD_NATURAL = (1 << 2)
+ USER_TRACKPAD_NATURAL = (1 << 2),
+ USER_MY_PROPERTY = (1 << 3)
===================================================================
</pre>

== RNA ==

; RNA is the python interface.
; Before you can use the property in user preferences with python, you need to setup the interface.

; Open blender\source\blender\makesrna\intern\rna_userdef.c
; Look for the, rna_def_userdef_view function.
; Scroll down to /* display */.

; Copy the code from a bool type property, then add it to the end of the /* display */ section.
; Modify the names.
: "my_property"
: "uiflag2"
: USER_MY_PROPERTY
: "Property"
: "My Property"

<pre>
Index: source/blender/makesrna/intern/rna_userdef.c
===================================================================
+ prop = RNA_def_property(srna, "my_property", PROP_BOOLEAN, PROP_NONE);
+ RNA_def_property_boolean_sdna(prop, NULL, "uiflag2", USER_MY_PROPERTY);
+ RNA_def_property_ui_text(prop, "Property", "My Property");
+
===================================================================
</pre>

== Python ==

; Open blender\release\scripts\startup\bl_ui\space_userpref.py

; Add the property to the display section.

<pre>
Index: release/scripts/startup/bl_ui/space_userpref.py
===================================================================
+ col.prop(view, "my_property")
===================================================================
</pre>

; Compile blender.

; If all works, you should see and be able to set "my_property" in User_Preference, Interface.

; You can now use this bool/property for conditional code in C or Python.
