Openerp - 如何在树视图标题区域调用自定义按钮

Question

我正在使用Openerp 7，我需要在树视图标题区域（创建或导入旁边）上调用自定义按钮。是否可以这样做？

这就是我需要移动的按钮的方式;

<record model="ir.ui.view" id="edit_roster_substitution_form">
            <field name="name">leave.score.card.form</field>
            <field name="model">leave.score.card</field>
            <field name="arch" type="xml">
                <form string="Leave Score Card"  version="7.0">
                 <sheet>

                        <button string="Generate" type="object" name="populate_values" class="oe_highlight"/>

                   </sheet> 
                   </form>
            </field>
        </record>

树状视图，

<record model="ir.ui.view" id="view_leave_score_card_tree">
            <field name="name">leave.score.card.tree</field>
            <field name="model">leave.score.card</field>
            <field name="arch" type="xml">

            <tree string="Leave Score Card To the Date" colors="red:available_medical &lt; 0.0; red:available_casual &lt; 0.0">                     
                        <field name="employee_id"  />
                        <field name="category_id" />
                        <field name="taken_medical" />
                        <field name="taken_casual" />
                        <field name="taken_annual" />
                        <field name="taken_spc" />      
                        <field name="available_medical" />
                        <field name="available_casual" />
                        <field name="available_annual" />
                        <field name="available_spc" />
                        <field name="sec_id" invisible="1" />
                        <field name="division_id" invisible="1" />
                        <field name="departmnt_id" invisible="1" />
                        <field name="comp_id" invisible="1" />
                        <field name="total_taken_leaves" invisible="1"/>

                </tree>
            </field>
        </record>

这是我的操作窗口和菜单调用

<record id="open_leave_score_card" model="ir.actions.act_window">
            <field name="name">Leave Score Card To the Date</field>
            <field name="type">ir.actions.act_window</field>
            <field name="res_model">leave.score.card</field>
            <field name="view_type">form</field>
            <field name="view_mode">tree,graph,form</field>
            <field name="view_id" eval="view_leave_score_card_tree"/>
            <field name="search_view_id" ref="view_leave_score_card_search"/>
        </record>

    <menuitem name="Leave Score Card" action="open_leave_score_card" id="menu_open_view_leave_score_card" parent="base.menu_reporting_dashboard" />

这是我的功能

def populate_values(self, cr, uid, ids, context={}):

        result = {'value': {}}
        today = datetime.datetime.now()
        tt=today.date()
        emps=self.pool.get('hr.employee').search(cr, uid, [('current_status','=','active')], context=context)
        if emps:

            for employees in emps:

                #result['value']['employee_id'] = employees
                print employees

                holiday_obj=self.pool.get('hr.holidays')
                holiday_emps_allocate=holiday_obj.search(cr, uid, [('employee_id','=',employees),('type','=','add'),('state','=','validate')], context=context)
                holiday_emps_taken=holiday_obj.search(cr, uid, [('employee_id','=',employees),('type','=','remove'),('state','=','validate')], context=context)

                .
                .
                .

我期待的是

是否可以这样做？
