У меня есть кнопки QB, расположенные так, как в первом ряду четыре кнопки, а во втором - пять кнопок.Мой код разработан с использованием PyQt5 в Python2.7.
from PyQt5 import QtCore, QtGui, QtWidgets
import cv2
import time
import face_recognition.api as face_recognition
class Thread(QtCore.QThread):
changePixmap = QtCore.pyqtSignal(QtGui.QImage)
scaled_size = QtCore.QSize(640, 480)
def run(self):
cap = cv2.VideoCapture(1)
cap.set(3,1280);
cap.set(4,1024);
time.sleep(2)
while True:
ret, frame = cap.read()
if ret:
r=1
face_locations=[]
rescaleSize=480
if(frame.shape[0] > 480 and frame.shape[1] > 640):
r = rescaleSize / float(frame.shape[0])
dim = (int(frame.shape[1] * r), rescaleSize)
face_locations = face_recognition.face_locations(cv2.resize(frame, dim, fx=0.0, fy=0.0))
else:
face_locations = face_recognition.face_locations(frame)
for face_location in face_locations:
top, right, bottom, left = face_location
cv2.rectangle(frame,(int(right/r),int(top/r)),(int(left/r),int(bottom/r)),(0,255,0),2)
rgbImage = cv2.cvtColor(frame, cv2.COLOR_BGR2RGB)
convertToQtFormat = QtGui.QImage(rgbImage.data, rgbImage.shape[1], rgbImage.shape[0], QtGui.QImage.Format_RGB888)
p = convertToQtFormat.scaled(self.scaled_size, QtCore.Qt.KeepAspectRatio)
self.changePixmap.emit(p)
def scaled(self, scaled_size):
self.scaled_size = scaled_size
class PlayStreaming(QtWidgets.QLabel):
reSize = QtCore.pyqtSignal(QtCore.QSize)
def __init__(self):
super(PlayStreaming, self).__init__()
self.initUI()
@QtCore.pyqtSlot(QtGui.QImage)
def setImage(self, image):
self.label.setPixmap(QtGui.QPixmap.fromImage(image))
def initUI(self):
self.setWindowTitle("Image")
# create a label
self.label = QtWidgets.QLabel(self)
th = Thread(self)
th.changePixmap.connect(self.setImage)
self.reSize.connect(th.scaled)
th.start()
lay = QtWidgets.QVBoxLayout(self)
lay.addWidget(self.label, alignment=QtCore.Qt.AlignCenter)
def resizeEvent(self, event):
self.reSize.emit(self.size())
class UIWidget(QtWidgets.QWidget):
def __init__(self, parent=None):
super(UIWidget, self).__init__(parent)
# Initialize tab screen
self.tabs = QtWidgets.QTabWidget()
self.tab1 = QtWidgets.QWidget()
self.tab2 = QtWidgets.QWidget()
self.tab3 = QtWidgets.QWidget()
# Add tabs
self.tabs.addTab(self.tab1, "Face")
self.tabs.addTab(self.tab2, "Human")
self.tabs.addTab(self.tab3, "Vehicle")
# Create first tab
self.createGridLayout()
self.tab1.layout = QtWidgets.QVBoxLayout()
self.display = PlayStreaming()
self.tab1.layout.addWidget(self.display, stretch=1)
self.tab1.layout.addWidget(self.horizontalGroupBox)
self.tab1.setLayout(self.tab1.layout)
# Add tabs to widget
layout = QtWidgets.QVBoxLayout(self)
layout.addWidget(self.tabs)
def createGridLayout(self):
self.horizontalGroupBox = QtWidgets.QGroupBox("")
self.horizontalGroupBox.setStyleSheet("QGroupBox{ background-color: red; border: none;}")
layout = QtWidgets.QGridLayout()
layout.addWidget(QtWidgets.QPushButton('Test'),0,0)
layout.addWidget(QtWidgets.QPushButton('Run'),0,1)
layout.addWidget(QtWidgets.QPushButton('RescaleUp'),0,2)
layout.addWidget(QtWidgets.QPushButton('RescaleDown'),0,3)
layout.addWidget(QtWidgets.QPushButton('Set Faces'),1,0)
layout.addWidget(QtWidgets.QPushButton('FacePose'),1,1)
layout.addWidget(QtWidgets.QPushButton('Gender'),1,2)
layout.addWidget(QtWidgets.QPushButton('Age'),1,3)
layout.addWidget(QtWidgets.QPushButton('Recognize'),1,4)
self.horizontalGroupBox.setLayout(layout)
if __name__ == '__main__':
import sys
app = QtWidgets.QApplication(sys.argv)
w = UIWidget()
w.resize(1000, 800)
w.show()
sys.exit(app.exec_())
Мне нравится, когда первые четыре кнопки расположены на одинаковом расстоянии, а второй fuveкнопки также расположены на одинаковом расстоянии.Для этого изменения делаются как
class UIWidget(QtWidgets.QWidget):
def __init__(self, parent=None):
super(UIWidget, self).__init__(parent)
# Initialize tab screen
self.tabs = QtWidgets.QTabWidget()
self.tab1 = QtWidgets.QWidget()
self.tab2 = QtWidgets.QWidget()
self.tab3 = QtWidgets.QWidget()
# Add tabs
self.tabs.addTab(self.tab1, "Face")
self.tabs.addTab(self.tab2, "Human")
self.tabs.addTab(self.tab3, "Vehicle")
# Create first tab
self.createGridLayout()
self.tab1.layout = QtWidgets.QVBoxLayout()
self.display = PlayStreaming()
self.tab1.layout.addWidget(self.display, stretch=1)
self.tab1.layout.addWidget(self.horizontalGroupBox)
self.tab1.layout.addWidget(self.horizontalGroupBox2)
self.tab1.setLayout(self.tab1.layout)
# Add tabs to widget
layout = QtWidgets.QVBoxLayout(self)
layout.addWidget(self.tabs)
def createGridLayout(self):
self.horizontalGroupBox = QtWidgets.QGroupBox("")
self.horizontalGroupBox.setStyleSheet("QGroupBox{ background-color: red; border: none;}")
layout = QtWidgets.QGridLayout()
layout.addWidget(QtWidgets.QPushButton('Test'),0,0)
layout.addWidget(QtWidgets.QPushButton('Run'),0,1)
layout.addWidget(QtWidgets.QPushButton('RescaleUp'),0,2)
layout.addWidget(QtWidgets.QPushButton('RescaleDown'),0,3)
self.horizontalGroupBox.setLayout(layout)
self.horizontalGroupBox2 = QtWidgets.QGroupBox("")
self.horizontalGroupBox2.setStyleSheet("QGroupBox{ background-color: red; border: none;}")
layout = QtWidgets.QGridLayout()
layout.addWidget(QtWidgets.QPushButton('Set Faces'),0,0)
layout.addWidget(QtWidgets.QPushButton('FacePose'),0,1)
layout.addWidget(QtWidgets.QPushButton('Gender'),0,2)
layout.addWidget(QtWidgets.QPushButton('Age'),0,3)
layout.addWidget(QtWidgets.QPushButton('Recognize'),0,4)
self.horizontalGroupBox2.setLayout(layout)
Тогда между двумя QGroupBox есть пробел.
Как я могусделать так, чтобы не было зазора и чтобы первый ряд и второй ряд имели одинаково расположенные кнопки?
