问题 I am trying to make certain cells in my QTableWidget have different colored borders based on the information contained in an item(cell). I do not want to select those cells and use the selection-color styles because different cells need to be selected/highlighted. for ex. I have a table with 3 columns and 3 rows. All the cells have simple text in each of them. [] [Name] [Value] [Units] [1] [one] [1] [cm] [2] [two] [2] [in] [3] [three][3] [m] The 1st row is selected by the user and is

问题 I'm still learning Qt and I am indebted to the SO community for providing me with great, very timely answers to my Qt questions. Thank you. I'm quite confused on the idea of adding a header to a QTableWidget . What I'd like to do is have a table that contains information about team members. Each row for a member should contain his first and last name, each in its own cell, an email address in one cell, and office in the other cell. I'd to have a header above these columns to name them as

Is there anyway to add like a button in qtablewidget? But the date within the cell would stil have to be displaying, for example if an user double clicked a cell, could i send a signal like a button?

Is it possible to write the contents of a QTableWidget to a csv? I found a question about writing to an .xls using xlwt, but can't seem to get it to work using my code. def saveFile(self): filename = unicode(QtGui.QFileDialog.getSaveFileName(self, 'Save File', '', ".xls(*.xls)")) wbk = xlwt.Workbook() self.sheet = wbk.add_sheet("sheet") self.write() wbk.save(filename) def write(self): for col in range (self.coordinates.columnCount()): for row in range(self.coordinates.rowCount()): text=str(self.coordinates.item(row,col).text()) self.sheet.write(row,col,text) I get the following error: File "C:

Resize column width to fit into the QTableWidget pyqt

问题 I've googled around but I'm not able to find a solution to my problem. I have a QTableWidget with 2 columns and what I'm trying to do is to make them visible to the whole widget without the horizontal scrollbar to appear. With a picture it should be all clear: I have used Qt Designer to create the UI and some code to fill all the widgets and other stuff. So, first I resized th2 2 columns to the content with: self.statTable.resizeColumnToContents(0) self.statTable.resizeColumnToContents(1) and

How to make a column in QTableWidget read only?

I would like to have one column in QTableWidget NOT editable. In forums I have read a lot about some flags but could not manage to implement. Insert into the QTableWidget following kind of items: QTableWidgetItem *item = new QTableWidgetItem(); item->setFlags(Qt::ItemIsSelectable|Qt::ItemIsEnabled); Works fine! EDIT: QTableWidgetItem *item = new QTableWidgetItem(); item->setFlags(item->flags() ^ Qt::ItemIsEditable); This is a better solution. Thanks to @priomsrb. user2923436 The result of using XOR depends on what the current state is. I'd suggest using item->setFlags(item->flags() & ~Qt:

Set default alignment for cells in QTableWidget

由 与世无争的帅哥 提交于 2019-11-27 02:13:44
问题 I know you can set the alignment for each item using: TableWidget->item(0,0)->setTextAlignment(Qt::AlignLeft); However I would like to set a default alignment for all the cells in order to do not have to set it every time I create a new item. Is it possible? 回答1: Yes it is possible. But you need to understand you are not modifying a property of the table widget, but a property of the table widget item. First create your own item, and set it up as you want QTableWidgetItem * protoitem = new

PyQT QTableWidget extremely slow

问题 this is the code I use to fill a table drawn in QT Designer. Designed to be universal for any table, it works fine, but... When I try to show a datasat containing 18 columns and ~12000 rows, it just freezes for 30 seconds or more. So, what I am doing wrong and is there way to speed up, keeping the code still suitable for any table? That's my code: ...blablabla... self.connect(self, SIGNAL("set"), self.real_set) ...blablabla... def set_table(self, table, data): self.emit(SIGNAL('set'), table,
