问题 i have the following doubt regarding QTableView , i have added some code that changes the row background depending on what string the dataframe contains on the last column. def data(self, index, role=Qt.DisplayRole): if index.isValid(): if role == Qt.BackgroundRole: if df.iloc[index.row(),5] == "Ready for QC": return QBrush(Qt.yellow) if df.iloc[index.row(),5] == "In Progress": return QBrush(Qt.green) if role == Qt.DisplayRole: return str(self._data.iloc[index.row(), index.column()]) return

问题 hi i've tried all i can think of and had looked at hundreds of stack overflow questions about tables and delegate's, and scratched my head for hours looking at the documentation trying to understand the c++ language and i have not read anything clearly stating that there's limits to the of amount delegate's a table view can take and not take, now i hope i can say i've got a firm understanding of the basic's in pyside2 and pyqt5 especially with tables and models but the delegates is a bit mind

问题 I am implementing QAbstractTableModel and I would like to insert a QPushButton in the last column of each row. When users click on this button, a new window is shown with more information about this row. Do you have any idea how to insert the button? I know about delegating system but all examples are only about "how to edit color with the combo box"... 回答1: The model-view architecture isn't made to insert widgets into different cells, but you can draw the push button within the cell. The

问题 I'm now looking into JTables and have a bunch of business objects that I retrieve from the DB with Hibernate + Spring Data JPA. I love that Spring Data JPA handles all the cumbersome implementation of the DAL and was wondering if there's something similar for TableModel . Basically, I would have something along the lines of: public class GenericTableModel<T> extends AbstractTableModel And the GenericTableModel would use reflection and/or annotations to look into T . Does something like this

问题 The following is what I've currently tried. The header text changes color correctly but the background will not change from the default. template<typename T> inline QVariant TableModel<T>::headerData(int section, Qt::Orientation orientation, int role) const { //... else if(role == Qt::BackgroundRole) { return QBrush(m_display.headerBackground); } //... } How can I set the background color? 回答1: You can set the style sheet on the QTableView ui->tableView->setStyleSheet("QHeaderView::section {

问题 I have QTableView and QAbstractTableModel . I require rows to have height equal to 24. I know the only way to do this is by calling QTableView::setRowHeight . Since the model is dynamic it may be added new rows, but I don't want to call setRowHeight each time new row is added. How can I configure QTableView such that it uses the same height for new added rows or can a model be sent the height of rows? 回答1: For Qt versions < 5 QHeaderView *verticalHeader = myTableView->verticalHeader();

问题 This question already has answers here : background color of cells in QTableview, PySide2 (1 answer) PyQt Tableview background color based on text value rather than True or False (1 answer) Closed 6 months ago . I have a table view displaying a QAbstractTableModel, I managed to color a row within the data function but I just want to color the cell and not the entire row. i.e if the cell value = "In error" I want to color it in red I have tried to set a color to the cell using the setData

问题 I have some data which are represented by a class of my own ; to fix the ideas I give an example. class MyOwnModel(): def __init__(self, name="", number=0): self.name = name self.number = number I then have a list of such instances, that I want to represent in a QTableView . li = [MyOwnModel("a", 1), MyOwnModel("b", 2)] Then I see two strategies to make a QTableView from that : change MyOwnModel so that it subclasses QAbstractTableModel build a new QAbstractTableModel which mimics MyOwnModel
