Allow entry in QLineEdit only within range of QDoubleValidator

冷暖自知 提交于 2019-11-29 02:29:17
I have a set of QLineEdits that are supposed to accept double values within a certain range, (e.g., -15 to 15). I have something along these lines when setting up each: lineEdit->setValidator(new QDoubleValidator(minVal, maxVal, 5, lineEdit)); Ideally, the line edits would work such that only values in range can be entered. When I tried this out, I noticed that only numbers could be typed, as desired, but that they could still go out of range. How can I dynamically force the input to fit into the range (e.g., if range is -15 to 15 and user types a 1, then attempts to type a 9, it doesn't work

I want to retrieve plain text from QLineEdit() object. The text method returns a QString object. I just want a simple string object. I am using pyqt4. def n(self): new_label=QLineEdit() new_label.setText("txt") txt=self.new_label.text() self.name=txt txt should be a simple string not QString . To convert one QString in Python 2 , do this: self.name = unicode(self.new_label.text()) To automatically convert all QStrings, put this at the beginning of your code: import sip sip.setapi('QString', 2) # must be before any pyqt imports from PyQt4 import QtCore, QtGui If you do this, there's no need to
