PyQt5 Scrollable Label – Setting tool tip to the label part
In this article we will see how we can set tool tip to the label part of scroll label, when know we can make scrollable label with the help of inheriting a scroll class and making label in it, but when we set tool tip to the class object tool tip is set to the whole widget i.e label and the scroll bar as well.
In order to add tool tip the label part only we have to override the function of the object.
Steps for implementations –
1. Create a new class which inherits QScrollArea
2. Inside the class create vertical layout
3. Create a label and make it multi-line and add it to the layout
5. Over-ride the setText and text method for label
6. Over-ride setToolTip method and add tool tip to the label
7. Creat object of this class inside the main window class and setting text to it
8. Add tool tip to the object with the help ofsetToolTipmethod
Below is the implementation
# importing librariesfrom PyQt5.QtWidgets import * from PyQt5 import QtCore, QtGuifrom PyQt5.QtGui import * from PyQt5.QtCore import * import sys # class for scrollable labelclass ScrollLabel(QScrollArea): # constructor def __init__(self, *args, **kwargs): QScrollArea.__init__(self, *args, **kwargs) # making widget resizable self.setWidgetResizable(True) # making qwidget object content = QWidget(self) self.setWidget(content) # vertical box layout lay = QVBoxLayout(content) # creating label self.label = QLabel(content) # making label multi-line self.label.setWordWrap(True) # adding label to the layout lay.addWidget(self.label) # the setText method def setText(self, text): # setting text to the label self.label.setText(text) # getting text method def text(self): # getting text of the label get_text = self.label.text() # return the text return get_text # overriding setToolTip method def setToolTip(self, text): # setting tool tip to the label self.label.setToolTip(text) class Window(QMainWindow): def __init__(self): super().__init__() # setting title self.setWindowTitle("Python ") # setting geometry self.setGeometry(100, 100, 600, 400) # calling method self.UiComponents() # showing all the widgets self.show() # method for widgets def UiComponents(self): # text to show in label text = "There are so many options provided by Python to develop GUI " \ " There are so many options provided by Python to develop GUI" \ " There are so many options provided by Python to develop GUI" # creating scroll label label = ScrollLabel(self) # setting text to the label label.setText(text) # setting geometry label.setGeometry(100, 100, 150, 80) # setting tool tip label.setToolTip("It is tool tip") # create pyqt5 appApp = QApplication(sys.argv) # create the instance of our Windowwindow = Window() # start the appsys.exit(App.exec()) |
