Hi, I want to add a QT4 widget to a matplotlib figure, but the widget does not react to user input.
Here it is a test case:
from PyQt4 import QtGui, QtCore
from pylab import *
def test():
plot([1,2,3], lw=2)
qt4_interface(gcf())
class qt4_interface:
def __init__(self,fig):
QMainWin = fig.canvas.parent()
toolbar = QtGui.QToolBar(QMainWin)
QMainWin.addToolBar(QtCore.Qt.BottomToolBarArea, toolbar)
self.line_edit = QtGui.QLineEdit(parent=toolbar)
self.line_edit.editingFinished.connect(self.do_something)
toolbar.addWidget(self.line_edit)
def do_something(self, *args):
f = open('l','a'); f.write('yes\n'); f.flush(); f.close()
#close()
I run the script as "run -i qt4_test.py" from ipython. Then running test()
I get the figure with the additional widget but the do_something method is
never called.
Incidentally if I do a plot from ipython and then I type interactively
qt4_interface(gcf()), the qt4 widget is added to the figure and works
properly.
Any hints on how can I resolve this problem?
BTW, I'm running matplotlib official package (1.0.1) included in ubuntu
11.10.
Thanks,
Antonio
