Ida Pro and PyQt simple buttons connect

Question

how do i connect the buttons, in a Ida Pro using a script and PyQT. this script brings two buttons up. my script.

from idaapi import PluginForm
from PyQt4 import QtCore, QtGui
from PyQt4.QtGui import QWidget
from PyQt4.QtGui import QPushButton
import sip

class MyPluginFormClass(PluginForm):
    def OnCreate(self, form):
        """
        Called when the plugin form is created
        """
        # Get parent widget
        self.parent = self.FormToPyQtWidget(form)
        self.PopulateForm()

    def PopulateForm(self):

        # Create layout

        layout = QtGui.QHBoxLayout()
        btn1 = QtGui.QPushButton('world')
        btn2 = QtGui.QPushButton('hello')
        layout.addWidget(btn1)
        layout.addWidget(btn2)

        self.parent.setLayout(layout)

    def OnClose(self, form):
        """
        Called when the plugin form is closed
        """
        pass

plg = MyPluginFormClass()
plg.Show("Buttons")

normally i would do like this to call the buttons.

btn1 = QtGui.QPushButton()
btn1.setText("Hello")
btn1.clicked.connect(self.hello)

def hello():
    print "hello"

But appenrently either setText or clicked.connect dont work inside Ida. also it looks like that i cant call QAplication via ida pro, since ida itself is a application and frezzes if called.

Any idea how to make buttons work ? Regards

Answer 1

You would have to delete the app execution to make all work and change Qapplication to Qwidget.

here is my hello script with a little mini forum :) load in ida from either *.py or from script command be sure to have sip and Qt instal proberly This way You can disign plugins must faster and richer. and if you see i dont even import idaapi
