在这里我想使用listdir将Pixmap和文本添加到QLabel,我得到了我的文件名,但文件名正在循环合并,所以任何人都可以帮助我如何将我的文件名放在QLabel中。请帮助我谢谢
import os
from PyQt4 import QtCore, QtGui
class MyLabel(QtGui.QLabel):
def __init__(self):
super(MyLabel, self).__init__()
def paintEvent(self, event):
super(MyLabel, self).paintEvent(event)
pos = QtCore.QPoint(100, 100)
painter = QtGui.QPainter(self)
s = iter(os.listdir("/home/cioc/Documents/pos/images"))
# file1 = next(s)
painter.drawText(pos,"vegitables")#here in place of vegitables i want to print the my filenames
painter.setPen(QtGui.QColor(168, 34, 3))
class MainWindow(QtGui.QMainWindow):
def __init__(self, parent=None):
super(MainWindow, self).__init__(parent)
url = '/home/cioc/Documents/pos/images'
highlight_dir = url
self.scroll_area = QtGui.QScrollArea()
self.scrollArea = QtGui.QScrollArea(widgetResizable=True)
self.setCentralWidget(self.scrollArea)
content_widget = QtGui.QWidget()
self.scrollArea.setWidget(content_widget)
self.layout = QtGui.QGridLayout(content_widget)
self.files_it = iter([os.path.join(highlight_dir, file) for file in os.listdir(highlight_dir)])
try:
for row in range(3):
for column in range(3):
file = next(self.files_it)
pixmap = QtGui.QPixmap(file)
self.label = MyLabel()
self.label.setPixmap(pixmap)
self.layout.addWidget(self.label,row,column)
except StopIteration:
pass
if __name__ == '__main__':
import sys
app = QtGui.QApplication(sys.argv)
w = MainWindow()
w.setGeometry(500,300,800,400)
w.show()
sys.exit(app.exec_())
答案 0 :(得分:2)
似乎文本和像素图属性不能共存,因为建立一个后一个属性就被消除了。因此,可能的解决方案是保存一个新属性。
在这种情况下,我将使用QDirIterator来获取文件,并使用QTimer来稍微加载图像,因为如果您有很多图像,则应用程序示例将被延迟或冻结。
from PyQt4 import QtCore, QtGui
class MyLabel(QtGui.QLabel):
def paintEvent(self, event):
super(MyLabel, self).paintEvent(event)
painter = QtGui.QPainter(self)
painter.setPen(QtGui.QColor(168, 34, 3))
painter.drawText(self.rect(), QtCore.Qt.AlignCenter, self.my_text)
class MainWindow(QtGui.QMainWindow):
def __init__(self, parent=None):
super(MainWindow, self).__init__(parent)
highlight_dir = '/home/cioc/Documents/pos/images'
scrollArea = QtGui.QScrollArea(widgetResizable=True)
self.setCentralWidget(scrollArea)
content_widget = QtGui.QWidget()
scrollArea.setWidget(content_widget)
self._layout = QtGui.QGridLayout(content_widget)
self._it = QtCore.QDirIterator(highlight_dir)
self._row, self._col = 0, 0
QtCore.QTimer(self, interval=10, timeout=self.load_image).start()
@QtCore.pyqtSlot()
def load_image(self):
if self._it.hasNext():
pixmap = QtGui.QPixmap(self._it.next())
if not pixmap.isNull():
label = MyLabel(alignment=QtCore.Qt.AlignCenter)
label.my_text = self._it.fileName()
label.setPixmap(pixmap)
self._layout.addWidget(label, self._row, self._col)
self._col += 1
if self._col == 3:
self._row += 1
self._col = 0
if __name__ == '__main__':

更新:
@QtCore.pyqtSlot()
def load_image(self):
if self._it.hasNext():
pixmap = QtGui.QPixmap(self._it.next())
if not pixmap.isNull():
vlay = QtGui.QVBoxLayout()
label_pixmap = QtGui.QLabel(alignment=QtCore.Qt.AlignCenter, pixmap=pixmap)
label_text = QtGui.QLabel(alignment=QtCore.Qt.AlignCenter, text=self._it.fileName())
vlay.addWidget(label_pixmap)
vlay.addWidget(label_text)
vlay.addStretch()
self._layout.addLayout(vlay, self._row, self._col)
self._col += 1
if self._col == 3:
self._row += 1
self._col = 0
