How to create a simple user app?

[jn30360]

I've installed QT Creator (3.5.1) and created a simple form that I need to integrate into an existing python script. Are there simple, straightforward instructions on how to do this?

Hi and welcome to devnet,

Are you planning on using PyQt ?

[jn30360]

@SGaist The python program I have is PyCharm. (is that what you're asking?)

@jn30360 To use the Qt framework on Python you need to use libraries such as PyQt or PySide.

I have included the following code:

from pyside import QtCore
from pyside import QtGui
from pyside import QtUiTools
ui=QtUiTools.QUiLoader()
ui.load("frmMain.ui")

Not sure what you do next to access objects (i.e., pushbuttons, etc) on the form frmMain.

@jn30360 Hmm i don't think that's gonna work. try something like this:

from PySide import QtCore, QtGui, QtUiTools


def loadUiWidget(uifilename, parent=None):
    loader = QtUiTools.QUiLoader()
    uifile = QtCore.QFile(uifilename)
    uifile.open(QtCore.QFile.ReadOnly)
    ui = loader.load(uifile, parent)
    uifile.close()
    return ui


if __name__ == "__main__":
    import sys
    app = QtGui.QApplication(sys.argv)
    MainWindow = loadUiWidget(":/forms/myform.ui")
    MainWindow.show()
    sys.exit(app.exec_())

Hey that worked, thanks a lot. That gets the form open.

Can you point me to code that interfaces a pushbutton on the form? Need something like:

frmMain.pushbutton1_clicked:
if <condition1> and not <condition2> etc... :
<action>
else :
<action>

Just can't find any clear example of how to integrate objects on the form into the script. I've seen some instructions on slots/signals, but can't find clear instructions/examples on how to implement.
