搜索和過濾按鈕標籤名稱

Question

我是一個新手，編碼，和我試圖找到一種方法，有一個搜索欄僅過濾按鈕我want.I創建一個窗口的圖標文本按鈕，要根據按鈕標籤名稱

對其進行過濾，這裏是展示什麼，我想do.Also一個例子，所有這些圓圈標註名稱circleA，circleB，circleC，盤旋。如果我型圈，我想證明這名字

這裏是你想使用該戰略的一個簡單的例子。這使用按鈕，而不是icontextbuttons，但想法是相同的。結構是你想要複製的部分;整個事情被包裝在一個可擴展的columnLayout中，過濾器是帶有文本字段和按鈕的RowLayout，然後所有的按鈕都在第二個ColumnLayout中，當你顯示隱藏按鈕時，這些按鈕可以展開和收縮。

import maya.cmds as cmds 

# some dummy commands. Not the use of "_", which is 
# a lazy way to ignore the argument which Maya will 
# add to all callback functions 

def apple_command(_): 
    cmds.polyCube() 

def orange_command(_): 
    cmds.polySphere() 

def banana_command(_): 
    cmds.polyPlane() 

window = cmds.window(title = "filter") 
root = cmds.columnLayout() 
# filter button and text field 
header = cmds.rowLayout(nc=2) 
filter_field = cmds.textField() 
filter_button = cmds.button(label = 'filter') 
cmds.setParent("..") 

# hideable butttons 
button_list = cmds.columnLayout() 
# create a bunch of buttons, storing the name in a dictionary for easier filtering 
# this is a dictionary with the label of the button and the commands you want to 
# attach to the buttons 
button_names = { 
    'apples': apple_command, 
    'oranges': orange_command, 
    'bananas': banana_comand, 
    'mangoes': apple_command, 
    'coconuts': orange_command, 
    'durians': banana_command 
    } 

button_widgets = {} 
for button_name, button_command in button_names.items(): 
     button_widgets[button_name] = cmds.button(label = button_name, width = 160, c= button_command) 
     # in a real application you'd also make the buttons do something.... 


# this makes the filter button apply the filter 
# defining it down here lets it 'remember' the name of the filter 
# field and the contents of the button dictionary 
def apply_filter(*_): 
    # get the current text in the filter field 
    filter_text = cmds.textField(filter_field, q=True, text=True) 
    # loop over the dictionary, setting the visiblity of the button 
    # based on the key and the filter 
    for key, value in button_widgets.items(): 
     viz = True 
     if len(filter_text): 
      viz = filter_text.lower() in key.lower() 
     cmds.button(value, edit=True, visible = viz) 

# now hook it too the button 
cmds.button(filter_button, e=True, c= apply_filter) 
cmds.showWindow(window) 

基本上你做的是，當你創建一個按鈕成它們映射到實際GUI控件的字典，收集過濾器能夠名稱。然後你可以遍歷整個事物，根據過濾器設置可見性。在columnLayout中，當您更改其可見性時，它們將自動縮小差距。

您可以通過創建佈局和顯示/隱藏他們以同樣的方式，而不是管理個人控制使用上套控制這一招。
