You already use QTextStream::readLine() - so why do you read it with ifstream before? You simply read it twice for no reason.

Hi, More likely that not all your database data are loaded in memory. You would have to call fetchMore however beware that if you have big tables it's going to cost you more in RAM.

@VRonin I got it corrected! searchProxy->setSourceModel(modal); ui->tableView->setModel(searchProxy); should be put inside the search button method!

separate QTableWidget into a QTableView and a QStandardItemModel add a QSortFilterProxyModel as the model of QTableView and set the QStandardItemModel as the QSortFilterProxyModel's sourceModel call QSortFilterProxyModel::setFilterWildcard or QSortFilterProxyModel::setFilterRegExp to perform the searching See Basic Sort/Filter Model Example

@Lasith Instead of 100 use ui->tableWidget->rowCount().

@Stefan-Monov76 Since I am not using qml I am not sure what requirements there are. I am working with C++ where you distinguish between source (.cpp) and header (.h included in *.cpp) files. The compiler requires basically only the *.cpp files for compiling. The header files are found through INCLUDEPATH or also other means settings. Being lazy you could think of just added *.cpp files to your .pro. However, this is a really bad idea, because Qt creator cannot detect that those have changed respectively there might be no dependency on includes in your make. Sometimes you simply forget an include to add to .pro and I have noticed that those includes are searched. That it is working for you now, may have something to do with a rerun of qmake. Just wait and see, if teh problem comes back. Eventually for some reason qmake was not triggered. Note: Since I am not working with qml at all, I am not sure, if you are actually using qmake. Checkout if you actually have "Run qmake" under "Buld" available.

Never mind. QRegularExpression::escape() does exactly what I want.

See this, is very simple. I put a ColumnLayout in a drawer and modified the content to have a space to a header in the drawer and your actions list. Drawer { id: drawer width: Math.min(window.width, window.height) / 3 * 2 height: window.height ColumnLayout { anchors.fill: parent Rectangle { width: drawer.width height: 100 Label { text: "Change this pane as you desire" anchors.centerIn: parent wrapMode: Text.WordWrap } } ListView { id: listView currentIndex: -1 Layout.fillWidth: true Layout.fillHeight: true delegate: ItemDelegate { width: parent.width text: model.title highlighted: ListView.isCurrentItem onClicked: { if (listView.currentIndex != index) { listView.currentIndex = index titleLabel.text = model.title stackView.replace(model.source) } drawer.close() } } model: ListModel { ListElement { title: "Get New Pages"; source: "qrc:/pages/get_new_pages.qml" } ListElement { title: "Manage Pages"; source: "qrc:/pages/manage_pages.qml" } } ScrollIndicator.vertical: ScrollIndicator { } } } }

@mmoerdijk since Qt 5.10 there is a recursiveFilteringEnabled property on a QSortFilterProxyModel, which does exactly this.

@alogim You're sort of naively using the simplest form of the tree data structure. If I understand your question correctly you should look at some BSP tree structure implementations, as they seem to suit your case quite well.

Hi @Yatshan, and welcome to the Qt Dev Net! Sorry I don't have any experience with Scintilla, so I don't know how to solve your problem. Have you tried asking the person who created QsciScintilla?
