Not able to display Qlabel on PyQt4

pyqt set label text
pyqt qlabel font size
pyqt qpixmap

Hi i have posted the code below through which i'm unable to display label in pyqt4. Any suggestions would be helpful .

from PyQt4 import QtGui
from PyQt4 import QtCore
import sys

class Entry_view(QtGui.QWidget):
    def __init__(self, parent=None):
        QtGui.QWidget.__init__(self, parent)
        self.setGeometry(25, 25, 800, 480)

        label = QtGui.QLabel()
        label.setText("Welcome To Python GUI")
        label.resize(100, 50)
        # label.show(self)
        self.show()


if __name__ == '__main__':
app     = QtGui.QApplication(sys.argv)
myapp = Entry_view()
sys.exit(app.exec_())

Why did you set the text but don't process the app using thus:

app.processEvents() # On the QApplication.

Or just do:

label = QtGui.QLabel(text="Welcome to Python GUI!")

Or:

label = QtGui.QLabel("Welcomme To Python GUI!")

Or another way is:

label.show() # No widgets on it.

QLabel not showing text, The QLabel class allows us to create a widget that displays a text or an image. setFocus() method, we would not be able to display the selected text because  A QLabel object acts as a placeholder to display non-editable text or image, or a movie of animated GIF. It can also be used as a mnemonic key for other widgets. Plain text, hyperlink or rich text can be displayed on the label. The following table lists the important methods defined in QLabel class


You did not keep a reference to the label, so it got garbage-collected before it could be shown. Try this instead:

self.label = QtGui.QLabel(self)
self.label.setText("Welcome To Python GUI")
self.label.resize(100, 50)

QLabel, Toggle line numbers 1 import sys 2 from PyQt4.QtGui import * 3 4 app = QApplication(sys.argv) 5 6 label = QLabel() 7 pixmap  I can appreciate not being able to spend any time on it. So, if anyone can give me some insight into how to troubleshoot this issue, I would be all ears. I'm willing to do the legwork, but I don't know the plotly.js codebase so I don't know what to try/where to look.


code below is the solution ,

from PyQt4 import QtGui
from PyQt4 import QtCore
import sys

class Entry_view(QtGui.QWidget):
def __init__(self, parent=None):
    QtGui.QWidget.__init__(self, parent)
    self.setGeometry(25, 25, 800, 480)

    label = QtGui.QLabel()
    label.setText("Swipe The Card")
    vbox = QtGui.QVBoxLayout()
    label.setAlignment(Qt.AlignCenter)
    vbox.addWidget(label)
    vbox.addStretch()
    self.setLayout(vbox)

if __name__ == '__main__':
app     = QtGui.QApplication(sys.argv)
myapp = Entry_view()
sys.exit(app.exec_())

PyQt/Show an image using a label, 1. create a small pyqt app with label with pixmal displaying any jpg image 2. 3. -label should display the jpg image specified. but not displayi QLabel(win) pixmap = QtGui. Cannot reproduce with PyScripter v2.0. You did not keep a reference to the label, so it got garbage-collected before it could be shown. Try this instead: self.label = QtGui.QLabel(self) self.label.setText("Welcome To Python GUI") self.label.resize(100, 50)


PyQt not displaying jpgs · Issue #367 · pyscripter/pyscripter · GitHub, The QLabel widget provides a text or image display. in plain format but cannot control the text source (for instance when displaying data loaded from the Web). By default, labels display left-aligned, vertically-centered text and images, where any tabs in the text to be displayed are automatically expanded. However, the look of a QLabel can be adjusted and fine-tuned in several ways. The positioning of the content within the QLabel widget area can be tuned with setAlignment() and setIndent().

PyQt - QLabel Widget, PyQt (via Qt) provides an straightforward interface to do exactly that. On Windows you may see the window turn pale, indicating it is not responding, while Sometimes it's helpeful to be able to pass back state and data from running workers. Up to this was the loading of the image located in your Device. Now to display the loaded image, we have two common options. Either we can use QGraphicsViewer or we can use QLabel widget to display the image to the PyQt5 window.
