问题

I've built a small program using python in maya, and im interested in printing the values that the user inputs upon the click of 'Apply'. Any ideas on how I can achieve this? I want to then use the values in another piece of code to create buildings inside maya.

def runGrid():
if mc.window('windowTest9', ex=True):
    mc.deleteUI('windowTest9', window=True)

mc.window('windowTest9', title='BuilGen', sizeable=False, resizeToFitChildren=True)

mc.rowColumnLayout( numberOfColumns = 2, columnWidth = [ (1, 150), (2, 100), (3, 75)])  

#mc.text( label = 'Top Bar')
mc.separator( h = 10, style = 'none')
mc.separator( h = 10, style = 'none')

mc.text(label='Create a New Building', align = 'left')
mc.image(image='F:\Photos\office-building-icon-687152.png')


# insert a blank line space
mc.separator( h = 10, style = 'singleDash')
mc.separator( h = 10, style = 'singleDash')


mc.text( label = 'number of sections wide:', align = 'left')
buildingWidth = mc.intField( value = 4)


mc.text( label = 'number of sections deep:', align = 'left')
buildingDepth = mc.intField( value = 3)    

mc.text( label = 'number of floors:', align = 'left')
numberOfFloors = mc.intField( value = 2)    


mc.text( label = 'roof:', align = 'left')
numberOfFloors = mc.checkBox (label='Y/N')    
mc.separator( h = 10, style = 'none')

# insert another blank line
mc.separator( h = 10, style = 'none')
mc.separator( h = 10, style = 'none')


# create the buttons
mc.separator( h = 10, style = 'none')
mc.button( label = 'Apply', command = '' )


mc.button( label = 'Cancel', command = 'mc.deleteUI("windowTest9", window=True)')

mc.showWindow()

runGrid()

Edit: Like DrWeeny said, it would be best to refer to the other similar topics.

I did a little reminder on my blog some time ago, to be able to test all the different native Maya UI way of using commands with a fast way of testing them:

classic maya string
function as argument
lambda
functools.partial
pymel.core.Callback

Each case is also given with examples with passing variables as arguments to those functions. Because sometimes you have to be able to. Overall I totally recommend the use functools.partial, it gives only advantages over the others (if you forget about PySide).

Maya UI types

def function(*args):
    print args
    cmds.textFieldGrp(text, edit=True, text=str(args))

variable = 'Variable'
width = [1, 250]
align = [1, 'left']
window = cmds.window(title='UI and commands arguments.')
cmds.columnLayout()

cmds.textFieldGrp(label="\"function()\"", changeCommand="function()", columnWidth=width, columnAlign=align)
cmds.textFieldGrp(label="function", changeCommand=function, columnWidth=width, columnAlign=align)
cmds.textFieldGrp(label="\"function(variable)\"", changeCommand="function(variable)", columnWidth=width, columnAlign=align)
cmds.textFieldGrp(label="lambda x: function(variable)", changeCommand=lambda x: function(variable), columnWidth=width, columnAlign=align)
cmds.separator(style="double", height=20)

import functools
cmds.textFieldGrp(changeCommand=functools.partial(function), label='functools.partial(function)', columnWidth=width, columnAlign=align)
cmds.textFieldGrp(changeCommand=functools.partial(function, variable), label='functools.partial(function, variable)', columnWidth=width, columnAlign=align)
cmds.separator(style="single", height=20)

import pymel.core
cmds.textFieldGrp(changeCommand=pymel.core.Callback(function), label='pymel.core.Callback(function)', columnWidth=width, columnAlign=align)
cmds.textFieldGrp(changeCommand=pymel.core.CallbackWithArgs(function), label='pymel.core.CallbackWithArgs(function)', columnWidth=width, columnAlign=align)
cmds.textFieldGrp(changeCommand=pymel.core.CallbackWithArgs(function, variable), label='pymel.core.CallbackWithArgs(function, variable)', columnWidth=width, columnAlign=align)

cmds.separator(style="single", height=20)
text = cmds.textFieldGrp(label='RESULT: ', text='', width=500)
cmds.showWindow()

When using a class

Because it was not made with the use of class in mind, some ways does not work at all when you are in a class.

class MayaUI():
    def __init__(self):
        self.variable = 'Variable'
        self.width = [1, 250]
        self.align = [1, 'left']
        self.window = cmds.window(title='UI and commands arguments.')
        cmds.columnLayout()

        cmds.textFieldGrp(label="\"self.function()\"", changeCommand="self.function()", columnWidth=self.width, columnAlign=self.align)
        cmds.textFieldGrp(label="self.function", changeCommand=self.function, columnWidth=self.width, columnAlign=self.align)
        cmds.textFieldGrp(label="\"self.function(self.variable)\"", changeCommand="self.function(self.variable)", columnWidth=self.width, columnAlign=self.align)
        cmds.textFieldGrp(label="lambda x: self.function(self.variable)", changeCommand=lambda x: self.function(self.variable), columnWidth=self.width, columnAlign=self.align)
        cmds.separator(style="double", height=20)

        import functools
        cmds.textFieldGrp(changeCommand=functools.partial(self.function), label='functools.partial(self.function)', columnWidth=self.width, columnAlign=self.align)
        cmds.textFieldGrp(changeCommand=functools.partial(self.function, self.variable), label='functools.partial(self.function, self.variable)', columnWidth=self.width, columnAlign=self.align)
        cmds.separator(style="single", height=20)

        import pymel.core
        cmds.textFieldGrp(changeCommand=pymel.core.Callback(self.function), label='pymel.core.Callback(self.function)', columnWidth=self.width, columnAlign=self.align)
        cmds.textFieldGrp(changeCommand=pymel.core.CallbackWithArgs(self.function), label='pymel.core.CallbackWithArgs(self.function)', columnWidth=self.width, columnAlign=self.align)
        cmds.textFieldGrp(changeCommand=pymel.core.CallbackWithArgs(self.function, self.variable), label='pymel.core.CallbackWithArgs(self.function, self.variable)', columnWidth=self.width, columnAlign=self.align)

        # A bit more complicated
        _map = {'textFieldGrp': lambda arg:cmds.textFieldGrp(arg, query=True, text=True)}
        _com = lambda *args:args[0](self.variable, _map[args[1]](args[2]))
        cmds.textFieldGrp('textfieldName', changeCommand=pymel.core.Callback(_com, self.function, 'textFieldGrp', 'textfieldName'), label="pymel.core.Callback(_com, self.function, 'textFieldGrp', 'textfieldName') + lambdas", columnWidth=self.width, columnAlign=self.align)

        cmds.separator(style="single", height=20)
        self.text = cmds.textFieldGrp(label='RESULT: ', text='', width=500)
        cmds.showWindow()

    def function(self, *args):
        print args
        cmds.textFieldGrp(self.text, edit=True, text=str(args))

You can go on this other post to see the answers : Printing the label of a button when clicked or the usage of dictionnary here : Maya Python - Using data from UI

from functools import partial

def queryInputs(*args):
    #args0 = label01
    print(cmds.text(args[0], q=True, label = 1))
    #args[1] = int_01
    print(cmds.intField(args[1], q=True, v = 1))
    #args[2] = cb_01
    print(cmds.checkBox(args[2], q=True, v = 1))


def runGrid():
    if cmds.window('windowTest9', ex=True):
        cmds.deleteUI('windowTest9', window=True)

    cmds.window('windowTest9', title='BuilGen', sizeable=False, resizeToFitChildren=True)

    cmds.rowColumnLayout( numberOfColumns = 2, columnWidth = [ (1, 150), (2, 100), (3, 75)])  

    label_01 = cmds.text( label = 'number of sections wide:', align = 'left')
    int_01 = buildingWidth = cmds.intField( value = 4)

    cb_01 = numberOfFloors = cmds.checkBox (label='Y/N')    

    cmds.button( label = 'Apply', command = partial(queryInputs, label_01, int_01, cb_01) )

    cmds.button( label = 'Cancel', command = 'cmds.deleteUI("windowTest9", window=True)')

    cmds.showWindow()
