我希望有一个包含2或3列的表,其中的行在PyQt中显示图像和文本(我使用的是python3.5和PyQt 5)。首先我选择了QListWidget,但它仅限于一列。我发现QTableWidget是执行此操作的最佳方式。但是当我在表格中放置一个单元格的图像时,该单元格的文本没有显示在它的底部。如何让单元格在适当的位置显示文本和图像? 这是我的代码:
self.main_table = QTableWidget(self)
self.main_table.setGeometry(QRect(20, 140, 600, 330))
sizePolicy = QSizePolicy(QSizePolicy.Fixed, QSizePolicy.Fixed)
sizePolicy.setHorizontalStretch(0)
sizePolicy.setVerticalStretch(0)
sizePolicy.setHeightForWidth(self.main_table.sizePolicy().hasHeightForWidth())
self.main_table.setSizePolicy(sizePolicy)
self.main_table.setLayoutDirection(Qt.LeftToRight)
self.main_table.setLocale(QLocale(QLocale.Persian, QLocale.Iran))
self.main_table.setInputMethodHints(Qt.ImhNone)
self.main_table.setFrameShape(QFrame.NoFrame)
self.main_table.setVerticalScrollBarPolicy(Qt.ScrollBarAlwaysOff)
self.main_table.setHorizontalScrollBarPolicy(Qt.ScrollBarAlwaysOff)
self.main_table.setEditTriggers(QAbstractItemView.NoEditTriggers)
self.main_table.setTabKeyNavigation(False)
self.main_table.setShowGrid(False)
self.main_table.setCornerButtonEnabled(False)
self.main_table.setIconSize(QSize(210,150))
self.main_table.setRowCount(2)
self.main_table.setColumnCount(2)
self.main_table.setObjectName("main_table")
self.main_table.horizontalHeader().setVisible(False)
self.main_table.horizontalHeader().setHighlightSections(False)
self.main_table.verticalHeader().setVisible(False)
self.main_table.verticalHeader().setHighlightSections(False)
self.main_table.horizontalHeader().setDefaultSectionSize(250)
self.main_table.verticalHeader().setDefaultSectionSize(250)
self.item = QTableWidgetItem(QIcon('content/img/food.png'),'Food')
self.main_table.setItem(0 , 0, self.item)
答案 0 :(得分:1)
最简单的方法是使用创建自定义小部件,我们可以根据需要找到元素,下面的代码实现了顶部的图标和下面的文本。
class CustomWidget(QWidget):
def __init__(self, text, img, parent=None):
QWidget.__init__(self, parent)
self._text = text
self._img = img
self.setLayout(QVBoxLayout())
self.lbPixmap = QLabel(self)
self.lbText = QLabel(self)
self.lbText.setAlignment(Qt.AlignCenter)
self.layout().addWidget(self.lbPixmap)
self.layout().addWidget(self.lbText)
self.initUi()
def initUi(self):
self.lbPixmap.setPixmap(QPixmap(self._img).scaled(self.lbPixmap.size(),Qt.KeepAspectRatio))
self.lbText.setText(self._text)
@pyqtProperty(str)
def img(self):
return self._img
@img.setter
def total(self, value):
if self._img == value:
return
self._img = value
self.initUi()
@pyqtProperty(str)
def text(self):
return self._text
@text.setter
def text(self, value):
if self._text == value:
return
self._text = value
self.initUi()
然后通过setCellWidget()
函数添加小部件以添加它们,并使用resizeColumnsToContents()
和resizeRowsToContents()
缩放每个单元格的空间,如下所示:
class TableWidget(QTableWidget):
def __init__(self, parent=None):
QTableWidget.__init__(self, parent)
self.setColumnCount(5)
self.setRowCount(5)
for i in range(self.columnCount()):
for j in range(self.rowCount()):
lb = CustomWidget(str(i)+str(j), "/path/of/image")
self.setCellWidget(i, j, lb)
self.resizeColumnsToContents()
self.resizeRowsToContents()
self.cellClicked.connect(self.onCellClicked)
@pyqtSlot(int, int)
def onCellClicked(self, row, column):
w = self.cellWidget(row, column)
print(w.text, w.img)
if __name__ == '__main__':
import sys
app = QApplication(sys.argv)
tw = TableWidget()
tw.show()
sys.exit(app.exec_())
