Hello i have do as follow:
def on_pushButton_5_clicked(self):
"""
Slot documentation goes here.
"""
# TODO: not implemented yet
#raise NotImplementedError
gra = QtGui.QPainter(self.miaPictureFrame.immagine)
import math
from time import sleep
nome_cal = self.lineEdit.text()
if nome_cal =='':
while 2 :
dlg_line = QtGui.QMessageBox.warning(self,'Pls Attention',
'You must insert a name for the calibration', QtGui.QMessageBox.Cancel)
break
else :
pen = QtGui.QPen()
pen.setWidth(1)
#disegno contorno grafico
gra.setPen(pen)
gra.drawText(30, 35, '50 daN/mm')
gra.drawText(395, 30, nome_cal)
gra.drawText(30, 430, '0')
gra.drawText(30, 240, '25')
gra.drawText(816,430, '0')
gra.drawText(816, 240, '90')
gra.drawText(806, 35, 'Deg 180')
gra.drawText(395, 480, 'Frequency Hz')
gra.drawText(55, 445, '0')
gra.drawText(796, 445, '120')
gra.drawLine(60,40,60,430)
gra.drawLine(60, 40, 801, 40)
gra.drawLine(801, 40, 801, 430)
gra.drawLine(60, 430, 801, 430)
self.frame1.updtate()
#here i simulate a real time graph.
sleep(3)
gra.drawText(30,50,'blabla')
self.frame1.update()
then i have write this class that for my understanding is called every
frame1.update:
class PictureFrame(QtGui.QFrame):
def __init__(self, parent):
QtGui.QFrame.__init__(self, parent)
self.setGeometry(QtCore.QRect(0,0, 961, 601))
self.immagine = QtGui.QPicture()
def paintEvent(self, event):
gr = QtGui.QPainter(self)
gr.drawPicture(0, 0, self.immagine)
the problem now is that the graph is show only at the second update whit all
texts and lines inside, and not after the first and then after the second
update.
How i can solve the problem
Regards
Luca
Thanks Luca
