Python-浏览后更改textField-MAYA [英] Python - Change the textField after browsing - MAYA

问题描述

我在Maya中的GUI导出器遇到了最烦人的问题.我已经使textField等工作了，但是在创建textField之后，我无法更改它的值，这是我需要做的.

I've got the most annoying problem with my GUI Exporter in Maya. I've made the textField etc. work, but I can't change the value of the textField after it's created, which is what I need to do.

例如，我想做的是，假设文件路径从一开始就没有.现在，textField已打印出来:"None"，但是在按浏览并选择目录后，我希望它将None更改为目录路径等.

What I want to do for example is, let's say the filepath is none from the beginning. The textField has now printed out: "None" in it, but after you press browse and select a directory, I want it to change None to the directory path etc.

这是我目前遇到的唯一问题，收到的错误代码是:

That's the only problem I currently have and the error code received is this:

代码:

#Setup the window using the returned window

def setupWindow(self, new_window):
    try:
        frame_layout = pm.frameLayout(labelVisible = False, marginWidth = 5, marginHeight = 5)
        pm.columnLayout(w = 350, h = 300)            

        pm.text(label = "Filepath: ")

        self.textField = pm.textField("FieldNorm", text = "%s" % self.filePath, editable = False, w = 350, h = 20)            

        pm.button(label = "Browse", w = 100, h = 20, command = self.browse)
        pm.rowLayout(numberOfColumns = 2, adjustableColumn = 1, w = 350, h = 25)
        pm.button(label = "Export", w = 200, h = 25, command = self.export)
        pm.button(label = "Close", w = 100, h = 25, command = pm.Callback(self.closeButton, new_window))
    except:
        print "<Setting up window failed>"

#Show the returned window        
def showWindow(self, new_window):
    if new_window is not None:
        pm.showWindow(new_window)
    else:
        print "<Window does not exist!>"

#Browse Directory and Paste into textField        
def browse(self, filePath):
    self.filePath = pm.fileDialog2(dialogStyle = 2, returnFilter = 1, fileFilter = "*.obj")

    if self.filePath is not None:
        self.textField = pm.textField("FieldNorm", text = "%s" % self.filePath, editable = False, w = 350, h = 20)
    else:
        print "<No changes has been made!>"

推荐答案

该错误表示您正在添加一个新控件，可能是在setupWindow函数末尾的行布局中，该控件包含两个按钮-Maya认为您正在添加三分之一

The error means you are adding a new control, probably to the rowlayout at the end of the setupWindow function which holds the two buttons - Maya thinks you're adding a third

如果要在浏览功能中更新self.textfield的内容，则需要

If you want to update the contents of self.textfield in the browse functions, you want

   pm.textField(self.textField, e=True, text = "%s" % self.filePath, editable = False, w = 350, h = 20)

将编辑已创建的字段.示例中的行

which will edit the already created field. The line in the example

    self.textField = pm.textField("FieldNorm", text = "%s" % self.filePath, editable = False, w = 350, h = 20)

正尝试创建一个新的，如@julianMann指出的

is trying to create a new one, as @julianMann points out
