import pymel.core as pm

def changeText():
    # 获取textFieldButtonGrp组件的当前文本值
    text = pm.textFieldButtonGrp('myTextFieldButtonGrp', query=True, text=True)
    
    # 对文本进行处理，例如添加前缀或后缀
    newText = 'New Text: ' + text
    
    # 修改textFieldButtonGrp组件的文本值
    pm.textFieldButtonGrp('myTextFieldButtonGrp', edit=True, text=newText)
    
    # 更新界面以反映新的文本值
    pm.refresh()

# 创建按钮和textFieldButtonGrp组件
with pm.window(title='Change Text Example'):
    with pm.columnLayout(adjustableColumn=True):
        textFieldButtonGrp = pm.textFieldButtonGrp('myTextFieldButtonGrp', label='Text:', buttonLabel='Change', buttonCommand=changeText)

# 显示界面
pm.showWindow()
