Use of Pyqt's QTableWidget component
QTableWidgetis a table control in PyQt6 for displaying and editing two-dimensional tabular data. It inherits fromQTableView, provides an easier way to process tabular data, suitable for scenarios where structured data is required.
1. Common methods
1.1 Constructor
QTableWidget(parent: QWidget = None): Create an empty table control.QTableWidget(rows: int, columns: int, parent: QWidget = None): Create a table control that specifies the number of rows and columns.
1.2 Set the number of rows and columns
setRowCount(rows: int): Set the number of rows in the table.setColumnCount(columns: int): Set the number of columns in the table.rowCount() -> int: Get the number of rows in the table.columnCount() -> int: Get the number of columns in the table.
1.3 Setting the table header
setHorizontalHeaderLabels(labels: List[str]): Set the label of the horizontal table header.setVerticalHeaderLabels(labels: List[str]): Set the label of the vertical header.horizontalHeader() -> QHeaderView: Get the horizontal table header object.verticalHeader() -> QHeaderView: Get the vertical header object.
1.4 Set cell content
setItem(row: int, column: int, item: QTableWidgetItem): Set the contents of the specified cell.item(row: int, column: int) -> QTableWidgetItem: Get the contents of the specified cell.takeItem(row: int, column: int) -> QTableWidgetItem: Removes the contents of the specified cell and returns.
1.5 Set cell properties
setCellWidget(row: int, column: int, widget: QWidget): Place a control (such as buttons, drop-down boxes, etc.) in the specified cell.cellWidget(row: int, column: int) -> QWidget: Gets the control in the specified cell.setSpan(row: int, column: int, rowSpan: int, columnSpan: int): Merge cells.
1.6 Select Mode
setSelectionMode(mode: ): Set selection mode (such as single-select, multiple-select, etc.).setSelectionBehavior(behavior: ): Set selection behavior (such as selecting rows, selecting columns, etc.).
1.7 Signal
cellChanged(row: int, column: int): Triggered when the cell content changes.cellClicked(row: int, column: int): Triggered when the cell is clicked.cellDoubleClicked(row: int, column: int): Fired when the cell is double-clicked.
2. Example
import os
import sys
import webbrowser
import qt_material
from import *
from import *
class Window(QWidget):
def __init__(self):
super(Window, self).__init__()
(400, 300)
self.init_widget()
self.init_signal()
self.init_getdata()
self.init_layout()
def init_widget(self):
# tablewidget
= QTableWidget()
(2)
(['website', 'Url'])
().setSectionResizeMode()
(True)
() # Cannot edit
def init_getdata(self):
row_count = ()
(row_count + 1)
(0, 0, QTableWidgetItem('Baidu'))
(0, 1, QTableWidgetItem('/'))
row_count = ()
(row_count + 1)
(1, 0, QTableWidgetItem('Tencent Video'))
(1, 1, QTableWidgetItem('/'))
def init_signal(self):
(self.open_url) # Double-click to open the web page
def init_layout(self):
v_layout = QVBoxLayout()
v_layout.addWidget()
(v_layout)
def open_url(self, row, column):
print(f'{row} {column}')
if int(column) == 1:
url = (row, column).text()
(url)
if __name__ == '__main__':
["QT_IM_MODULE"] = "ibus" # mac system solves incompatible input method
app = QApplication()
qt_material.apply_stylesheet(app, theme='light_pink.xml')
window = Window()
()
(())
3. Summary
advantage
Simple and easy to use: Provides an interface for directly manipulating table data.
High flexibility: Supports dynamic loading of data, editing cell content and embedding controls.
Rich features: Supports functions such as header setting, cell merging, and selection mode.
Applicable scenarios
Data display (such as grade tables, inventory tables).
Data editing (such as employee information management, order management).
Dynamic data loading (such as database query results, CSV file data).
