====== Autocompletion and calltip tests for PyQt4 on various IDEs ======


===== Tempalate =====
<code python main.py>
if __name__ == '__main__':
    # create application
    app = QApplication(sys.argv)
    app.setApplicationName('My PyQt4 QtGui Project')
    # create widget
    w = MainWindow()
    w.setWindowTitle('My PyQt4 QtGui Project')
    w.show()
    # connection
    QObject.connect(app, SIGNAL('lastWindowClosed()'), app, SLOT('quit()'))
    # execute application
    sys.exit(app.exec_())
    ############################
    open()
</code>
This is from my {{:qt:evalpyqt.zip|EvalPyQt}} example project (except for the last line). All IDEs were set up with this project. Then everything after <code python>if __name__ == '__main__':</code> in ''main.py'' was removed and the document saved. Then the code was retyped.

===== Eclipse + PyDev =====
<code python>
if __name__ == '__main__':
    # create application
    app = QApplication(sys.argv) # good
    app.setApplicationName('My PyQt4 QtGui Project') # requesting completion removed calltip
    # create widget
    w = MainWindow() # good
    w.setWindowTitle('My PyQt4 QtGui Project') # w's setWindowTitle not detected, no calltip
    w.show() # w's show not detected
    # connection
    QObject.connect(app, SIGNAL('lastWindowClosed()'), app, SLOT('quit()')) # completion inserted useful placeholders :-)))
    # execute application
    sys.exit(app.exec_()) # good
    ############################
    open() # good, placeholder inserted
</code>
=> Major disadvantage over Spyder: calltips disappear the instant you hit a completing ')' -- even when auto-close brackets is enabled. Disabling autoclose ')' also disables autoclose of ']', and '}'
Syntax error markers can be slow and obtrusive.

===== Editra =====
<code python>
if __name__ == '__main__':
    # create application
    app = QApplication(sys.argv) # good
    app.setApplicationName('My PyQt4 QtGui Project') # good
    # create widget
    w = MainWindow() # didn't find MainWindow
    w.setWindowTitle('My PyQt4 QtGui Project') # didn't find setWindowTitle
    w.show() # didn't find show
    # connection
    QObject.connect(app, SIGNAL('lastWindowClosed()'), app, SLOT('quit()')) # good
    # execute application
    sys.exit(app.exec_()) #good
    ############################
    open() # calltip very helpful
</code>
Calltips remain onscreen throughout typing.

===== Eric (Assistant handles both) =====
<code python>
if __name__ == '__main__':
    # create application
    app = QApplication(sys.argv) # didn't detect sys.argv
    app.setApplicationName('My PyQt4 QtGui Project') # slow to find stuff
    # create widget
    w = MainWindow() # good
    w.setWindowTitle('My PyQt4 QtGui Project') # suggested all sorts of irrelevant stuff
    w.show() # suggested all sorts of irrelevant stuff
    # connection
    QObject.connect(app, SIGNAL('lastWindowClosed()'), app, SLOT('quit()')) # suggested all sorts of irrelevant stuff, calltip useful
		# found and suggested SIGNAL and SLOT!
    # execute application
    sys.exit(app.exec_()) # found app.exec_ but also suggested all sorts of irrelevant stuff
    ############################
    open() # didn't find built-in open but suggested many others
</code> 
Calltips remain onscreen throughout typing.

===== Eric (Rope for autocomplete, Assistant for calltips) =====
<code python>
if __name__ == '__main__':
    # create application
    app = QApplication(sys.argv) # good
    app.setApplicationName('My PyQt4 QtGui Project')  # good
    # create widget
    w = MainWindow() # good
    w.setWindowTitle('My PyQt4 QtGui Project') # ac, didn't find setWindowTitle method; calltip suggested useful stuff
    w.show() # ac, didn't find show method; calltip suggested useful stuff
    # connection
    QObject.connect(app, SIGNAL('lastWindowClosed()'), app, SLOT('quit()')) # good; didn't find SIGNAL ac but found calltip
    # execute application
    sys.exit(app.exec_()) # app.exec_ calling was irrelevant
    ############################
    open() # didn't find built-in open but suggested many others
</code>
Calltips remain onscreen throughout typing.

===== Spyder =====
<code python>
if __name__ == '__main__':
    # create application
    app = QApplication(sys.argv) # worked, but calltip/doc not that helpful
    app.setApplicationName('My PyQt4 QtGui Project') # good
    # create widget
    w = MainWindow() # good
    w.setWindowTitle('My PyQt4 QtGui Project') # w's setWindowTitle not detected, no calltip
    w.show() # w's show not detected
    # connection
    QObject.connect(app, SIGNAL('lastWindowClosed()'), app, SLOT('quit()')) # good, calltip/doc not that helpful
        # no help at all in suggesting signals and slots
    # execute application
    sys.exit(app.exec_()) # no ac until 'sys.e', calltip not helpful; ac at 'app.e', calltip helpful!
    ############################
    open() # completion at 'o', calltip/doc is helpful
</code>    
A huge win for Spyder is that the docs remain onscreen after the calltips have disappeared.
Syntax error markers can be very slow.
