area split via Python

Hey there,<br>
<br>
i’m new to this forum.<br>
I need to split an area after pressing a button operator. In my execute definition of the operator i call ‘bpy.ops.screen.area_split(direction=‘HORIZONTAL’, factor = 0.5, mouse_x = -100, mouse_y=-100)’ and as I suspected it won’t work. How can I define the concrete area to split?<br>
And also if I enable a shortcut for area split in the system settings, nothing will change when pressing the key.<br>
<br>
Oh and i’m using Blender 2.71…<br>
<br>
Hope anyone can help :-)<br>
Thanks and greetings<br>

Here is an example you could take a look at:

https://github.com/dustractor/areatype_split/blob/master/areatype_split_view_w_uv.py

It puts a button on the 3d view header that you can click to toggle a split with the image editor, but it should be easy to modify where it goes and what space-type it splits with.

import bpy


class AREATYPE_OT_split(bpy.types.Operator):
    bl_idname = "areatype.splitview"
    bl_label = "areatype.splitview"
    def execute(self,context):
        thisarea = context.area
        otherarea = None
        tgxvalue = thisarea.x + thisarea.width + 1
        thistype = context.area.type
        arealist = list(context.screen.areas)
        for area in context.screen.areas:
            if area == thisarea:
                continue
            elif area.x == tgxvalue and area.y == thisarea.y:
                otherarea = area
                break
        if otherarea:
            bpy.ops.screen.area_join(min_x=thisarea.x,min_y=thisarea.y,max_x=otherarea.x,max_y=otherarea.y)
            bpy.ops.screen.screen_full_area()
            bpy.ops.screen.screen_full_area()
            return {"FINISHED"}
        else:
            context.area.type = "IMAGE_EDITOR"
            areax = None
            bpy.ops.screen.area_split(direction="VERTICAL")
            for area in context.screen.areas:
                if area not in arealist:
                    areax = area
                    break
            if areax:
                areax.type = thistype
                return {"FINISHED"}
        return {"CANCELLED"}


def viewdraw(self,context):
    layout = self.layout
    layout.operator("areatype.splitview",text="",icon="COLOR_BLUE")


def register():
    bpy.types.VIEW3D_HT_header.prepend(viewdraw)
    bpy.utils.register_module(__name__)


def unregister():
    bpy.types.VIEW3D_HT_header.remove(viewdraw)
    bpy.utils.unregister_module(__name__)

Thank you! That was what I was looking for!
