Question

我是编码的新手，我正试图找到一种方法让搜索字段只过滤我想要的按钮。我在窗口中创建了一个图标文本按钮，并希望根据按钮标签名称对其进行过滤

这是一个显示我想要做的事情的示例。此外，所有这些圈子标签名称都是circleA，circleB，circleC，circleD。如果我输入圆圈，我想显示具有该名称的按钮

我发现这个页面完全符合我的要求但是，如何更改以便查找标签名称并仅显示我输入的那个。另外，默认情况下我要显示所有图标

以下是您想要使用的策略的简单示例。这使用按钮，而不是icontext按钮，但想法是一样的。结构是你想要复制的部分;整个事情包含在columnLayout中以便扩展，过滤器是带有文本字段和按钮的RowLayout，然后所有按钮都在第二个columnLayout中，可以在显示 - 隐藏按钮时展开和收缩。

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，您所做的是在将按钮创建到将其映射到实际GUI小部件的字典中时收集可过滤的名称。然后你可以循环整个过程，根据过滤器设置可见性。在columnLayout中，当您更改其可见性时，它们会自动缩小差距。

您可以通过创建布局并以相同的方式显示/隐藏它们而不是管理单个控件来在控件集上使用此技巧。

在maya mel中搜索并过滤按钮标签名称
