@Osama_Billah said in How to enter Images in a listWidget inside tabWidget:

'QWidget' object has no attribute 'clicked'

The error tells you what is wrong - there is no clicked signal. What type is tab_2?

I doubt this is going to work:

def images_for_tab2(self):
        ls1 = ["C:/Users/OB/Desktop/DevoMech Project/4.JPG" , "C:/Users/OB/Desktop/DevoMech Project/5.JPG" , "C:/Users/OB/Desktop/DevoMech Project/4.JPG"]
        self.listWidget.addItem(ls1)

This way you add strings not images.
Take a look at what @anil_arise gave you.

Osama_Billah

as the images come from a website so every time the number of images and Videos will be change

JonB

@Osama_Billah
You still presumably do not want to add them all as a single string item, as you have done, do you?

Don't you want to use https://doc.qt.io/qt-5/qlistwidget.html#addItems for a list, not just one item via addItem(const QString &label)?

jsulm

@Osama_Billah said in How to enter Images in a listWidget inside tabWidget:

So what? It's your job to add them to the list. In the code you posted you add strings not images: please read documentation https://doc.qt.io/qt-5/qlistwidget.html#addItems This is to add a list of STRINGS, not images.
Again: take a look at what @anil_arise suggested...

Osama_Billah

@jsulm @anil_arise @SGaist oky thank you I'm checking that. as I'm new so It allow me to post after 10 min so sorry for late reply. and another question as I name the tab like tab1, tab2 so how can I call it. because it gave an error " 'QWidget' object has no attribute 'clicked' "

jsulm

@Osama_Billah said in How to enter Images in a listWidget inside tabWidget:

because it gave an error " 'QWidget' object has no attribute 'clicked' "

It's not clear to me what you're trying to achieve. If you want to get a signal if a tab was activated then use https://doc.qt.io/qt-5/qtabwidget.html#currentChanged

Osama_Billah

@jsulm I wanna to do this

self.tab_2.clicked.connect(self.images_for_tab2)

if the user click on tab_2 it call the own function.
@anil_arise as I write the code it gave an error on invalid syntax. I'm Using python.
Sorry for the trouble but I'm new learner.

jsulm

@Osama_Billah https://doc.qt.io/qt-5/qtabwidget.html#currentChanged
If you get errors please post your code and errors.

Osama_Billah

 self.tab.clicked.connect(self.images_for_tab1)

        self.retranslateUi(MainWindow)
        self.tabWidget.setCurrentIndex(2)
        QtCore.QMetaObject.connectSlotsByName(MainWindow)



    def images_for_tab1(self):
        #images in the list will come from a webURL

        QListWidget * listwidget = new QListWidget()
        #ui->tabWidget->addTab(listwidget,QIcon(":/img/alert.png"),"NewTab");

        QListWidgetItem *item1 = new QListWidgetItem(QIcon("C:/Users/OB/Desktop/DevoMech Project/4.JPG"),"item1")
        listwidget->addItem(item1)
        QListWidgetItem *item2 = new QListWidgetItem(QIcon("C:/Users/OB/Desktop/DevoMech Project/5.JPG" , "item2")
        listwidget->addItem(item2)

Osama_Billah

@jsulm @SGaist @anil_arise @JonB Thanks for your time. I know it's hard for all of you but I'm totally new and have no idea.

SGaist

You are mixing C++ syntax with Python syntax, that's the error you are getting. There's not pointer nor new operator in Python.

Osama_Billah

@SGaist I change it to this

        self.item1 = self.QListWidgetItem.QIcon("C:/Users/OB/Desktop/DevoMech Project/4.JPG", "item1")
        self.listWidget_3.addItem(item1)
        self.item2 = self.QListWidgetItem.QIcon("C:/Users/OB/Desktop/DevoMech Project/5.JPG", "item2")
        self.listWidget_3.addItem(item2)

Now the error is
Traceback (most recent call last):
File "C:\Users\OB\Desktop\DevoMech Project\test_for_de.py", line 127, in <module>
ui.setupUi(MainWindow)
File "C:\Users\OB\Desktop\DevoMech Project\test_for_de.py", line 83, in setupUi
self.item1 = self.QListWidgetItem.QIcon("C:/Users/OB/Desktop/DevoMech Project/4.JPG", "item1")
AttributeError: 'Ui_MainWindow' object has no attribute 'QListWidgetItem'

Osama_Billah

problem solved. thanks @SGaist @jsulm @anil_arise @JonB I just want to know that every beginner face these problems. or I'm the special one.

Osama_Billah

        item1 = QtWidgets.QListWidgetItem(QIcon("path_to_pic"), "Name_of_pic")
        self.listWidget_2.addItem(item1)
        item2 = QtWidgets.QListWidgetItem(QIcon("path_to_pic"), "Name_of_pic!
        self.listWidget_2.addItem(item2)

At the beginning we are all beginners :-)

Thanks for your response. One more thing how to convert these images horizontally and increase the size. @SGaist @jsulm @anil_arise @JonB

Osama_Billah

this is the code. I used QIcon the one @anil_arise suggest

self.tabWidget.setIconSize(QtCore.QSize(32, 32))
QtWidgets.QListWidgetItem.setLayoutDirection(QtCore.Qt.LeftToRight)
