我试图为QGroupBox制作两个滚动条,但我只成功拥有一个(垂直一个) 我不确定自己需要做什么。
这是我的代码的简短示例:
from PyQt5.QtGui import *
from PyQt5.QtCore import *
from PyQt5.QtWidgets import *
import sys
class SurfViewer(QMainWindow):
def __init__(self, parent=None):
super(SurfViewer, self).__init__()
self.parent = parent
self.centralTabs= QTabWidget()
self.setCentralWidget(self.centralTabs)
self.setFixedWidth(200)
self.setFixedHeight(200)
#tab Model selection
self.tab_ModelSelect = QWidget()
self.centralTabs.addTab(self.tab_ModelSelect,"Label")
self.groupscrolllayouttest = QHBoxLayout()
self.groupscrollbartest = QGroupBox()
self.mainHBOX_param_scene = QVBoxLayout()
for i in range(10):
Label = QLabel('BlaBlaBlaBlaBlaBlaBlaBlaBlaBlaBlaBlaBlaBlaBlaBlaBlaBla')
Label.setFixedWidth(200)
self.mainHBOX_param_scene.addWidget(Label)
#
scroll = QScrollArea()
scroll.setWidget(self.groupscrollbartest)
scroll.setWidgetResizable(True)
scroll.setFixedWidth(20)
scroll.setVerticalScrollBarPolicy(Qt.ScrollBarAsNeeded)
scroll.setHorizontalScrollBarPolicy(Qt.ScrollBarAsNeeded)
self.groupscrollbartest.setLayout(self.mainHBOX_param_scene)
self.groupscrolllayouttest.addWidget(self.groupscrollbartest)
self.groupscrolllayouttest.addWidget(scroll)
self.tab_ModelSelect.setLayout(self.groupscrolllayouttest)
def main():
app = QApplication(sys.argv)
ex = SurfViewer(app)
ex.setWindowTitle('window')
# ex.showMaximized()
ex.show()
sys.exit(app.exec_( ))
if __name__ == '__main__':
main()
以下是结果:
在我更复杂的代码中,我使用了QTabWidget,这就是我在这个例子中包含它的原因。我想要做的是在底部有一个水平滚动条,允许我左右移动文本。显然我想让另一个人上下移动文本。
我还尝试将第二个滚动条添加到第一个滚动条(groupscrolllayouttest)
from PyQt5.QtGui import *
from PyQt5.QtCore import *
from PyQt5.QtWidgets import *
import sys
class SurfViewer(QMainWindow):
def __init__(self, parent=None):
super(SurfViewer, self).__init__()
self.parent = parent
self.centralTabs= QTabWidget()
self.setCentralWidget(self.centralTabs)
self.setFixedWidth(200)
self.setFixedHeight(200)
#tab Model selection
self.tab_ModelSelect = QWidget()
self.centralTabs.addTab(self.tab_ModelSelect,"Label")
self.groupscrolllayouttest2 = QVBoxLayout() ####
self.groupscrollbartest2 = QGroupBox() ####
self.groupscrolllayouttest = QHBoxLayout() ####
self.groupscrollbartest = QGroupBox() ####
self.mainHBOX_param_scene = QVBoxLayout()
for i in range(10):
Label = QLabel('BlaBlaBlaBlaBlaBlaBlaBlaBlaBlaBlaBlaBlaBlaBlaBlaBlaBla')
Label.setFixedWidth(200)
self.mainHBOX_param_scene.addWidget(Label)
#
scroll = QScrollArea()
scroll.setWidget(self.groupscrollbartest)
scroll.setWidgetResizable(True)
scroll.setFixedWidth(20)
scroll.setVerticalScrollBarPolicy(Qt.ScrollBarAsNeeded)
scroll.setHorizontalScrollBarPolicy(Qt.ScrollBarAsNeeded)
# self.mainHBOX_param_scene.addWidget(scroll)
self.groupscrollbartest.setLayout(self.mainHBOX_param_scene)
self.groupscrolllayouttest.addWidget(self.groupscrollbartest)
self.groupscrolllayouttest.addWidget(scroll)
scroll2 = QScrollArea()
scroll2.setWidget(self.groupscrollbartest2)
scroll2.setWidgetResizable(True)
scroll2.setFixedWidth(20)
scroll2.setVerticalScrollBarPolicy(Qt.ScrollBarAsNeeded)
scroll2.setHorizontalScrollBarPolicy(Qt.ScrollBarAsNeeded)
self.groupscrollbartest2.setLayout(self.groupscrolllayouttest)
self.groupscrolllayouttest2.addWidget(self.groupscrollbartest2)
self.groupscrolllayouttest2.addWidget(scroll2)
self.tab_ModelSelect.setLayout(self.groupscrolllayouttest2)
def main():
app = QApplication(sys.argv)
ex = SurfViewer(app)
ex.setWindowTitle('window')
# ex.showMaximized()
ex.show()
sys.exit(app.exec_( ))
if __name__ == '__main__':
main()
但我最终得到了一个奇怪的滚动条:
所以现在我被卡住了。有什么想法吗?
答案 0 :(得分:2)
您需要做的是创建一个小部件,并在该小部件中放置QGroupBox:
[...]
scroll = QScrollArea()
widget = QWidget(self)
widget.setLayout(QVBoxLayout())
widget.layout().addWidget(self.groupscrollbartest)
scroll.setWidget(widget)
scroll.setWidgetResizable(True)
self.groupscrollbartest.setLayout(self.mainHBOX_param_scene)
self.groupscrolllayouttest.addWidget(scroll)
self.tab_ModelSelect.setLayout(self.groupscrolllayouttest)
[...]
输出:
