wow,thanks a lot Dave.I just wanted to try out Qt designer so I read
about PyQt and just installed it.
It is great,I just made a ui that took me in the past 3 days,in 1
hour.But I wasn´t sure about what PyQt exactly was.
Now I understand better.
I am having now some problems querying the values of the QlineEdit
widget.I just made a window with a QlineEdit:
<<
from PyQt4 import QtGui
from PyQt4.QtGui import *
myWindow=loadUI (uiFile ='C:/Users/rudi/Desktop/t/test.ui')
showWindow(myWindow)
>>
I have named in Qt designer the QLineEdit as txtFld_myLine
Now I don´t know how to get the string that the user writes
there.Maybe I am looking at the wrong documentation.
Does it have something to do with QtGui.QInputDialog.getText? because
I tryed something like that without success
<<
myText = QLineEdit("txtFld_myLine")
myName= QtGui.QInputDialog.getText()
>>
Beginings are allways hard,I started building UI in Tkinter,then
changed to do it directly with maya´s python,and now with PyQt,so I am
having some
troubles.
