Qt for Python

You can implement 'add row to QTableView' action for button in that way: from PyQt5.QtGui import QStandardItemModel, QStandardItem ... table = QTableView(...) table.setModel(QStandardtemModel()) addRowButton = QPushButton('Add row', ...) addRowButton.clicked.connect(lambda: table.model().insertRow(0, [QStandardItem('1'), QStandardItem('example'), ...])

@Tauri Read https://doc.qt.io/qt-5/qtquick-modelviewsdata-cppmodels.html#qvariantlist-based-model

@Black-Cat execute sudo apt-get install '^libxcb.*-dev'

You always have to set the baseUrl if you want to use setHtml, but if you want to repeat the code then create a method that does it: class Foo(Bar): def __init__(self, ...): super().__init(...) self._base_url = QUrl() self.base_url = QUrl.fromLocalFile(os.getcwd()+os.path.sep) self.webPage = ... @property def base_url(self): return self._base_url @base_url.setter def base_url(self, url): self._base_url = url def update_html(self, html): self.webPage.setHtml(html, self.base_url) then: self.update_html('<img src="image.png"/>');

@levoxtrip I don't know anything about your "fading", but QTextEdit::append() always appends the text at the end. To insert somewhere else it looks like you must use QTextEdit::insertHtml/insertPlainText(), and those insert at the current cursor position, so you may need to move it with QTextEdit::moveCursor/setPosition() or similar.

@danielcharles Why do you post a link to a video handling C#? This is Qt forum...

Hi, IIRC, the about dialog that you can trigger from the help menu should give you this answer.

Well thanks you

Hi and welcome to devnet, Are you using layouts to build your UI ?

@Willkroken I need to check 3 different columns to check what order the rows should be arranged in If you stick with a QTableWidget, you have to sort your table by your criteria before you put the rows into the table, so go ahead and do so. Or it seems to me if the answer at https://stackoverflow.com/a/18652060/489865 using You can try to subclass the QTableWidgetItem and reimplement operator<() of it. works that is possible, but I don't know how you override an operator from Python. If you move to a QTableView and have your own model, you can interpose a QSortFilterProxyModel and override lessThan() to do your 3 column comparison.

@benyeyeye use focusProxy(): from PyQt5 import QtCore, QtWidgets, QtWebEngineWidgets # or # from PySide2 import QtCore, QtWidgets, QtWebEngineWidgets class BetterWebView(QtWebEngineWidgets.QWebEngineView): def __init__(self): super().__init__() self.load(QtCore.QUrl()) self.focusProxy().installEventFilter(self) def eventFilter(self, source, event): if ( self.focusProxy() is source and event.type() == QtCore.QEvent.MouseButtonPress ): print("ok") return super().eventFilter(source, event) if __name__ == "__main__": import sys app = QtWidgets.QApplication(sys.argv) view = BetterWebView() view.load(QtCore.QUrl("https://www.qt.io")) view.show() sys.exit(app.exec_())

So apparently, this is due to the Dash debug mode. I don't know why, however. Change this line app.run_server(debug = True) to app.run_server()

@JonB Thanks. I use os.path.normpath everywhere to get rid of this kind of problems :)

Man thx a lot for your help! Really appreciate it

@jiri_otoupal said in Call python function from Custom Button: PyQt Quick Are you asking about a Qt Quick application? This is not clear. Are you interested in How to bind buttons in Qt Quick to Python PyQt 5 ?

@_jao_victor_ If you're using QTableView (please always tell what you're using, it is not even clear whether you're using widgets or QML!) then take a look at https://doc.qt.io/qt-5/stylesheet-examples.html#customizing-qheaderview
