PyQt4中的对齐按钮

这是我第一个使用PyQt4的应用程序。PyQt4中的对齐按钮

我有以下两个问题

enter image description here

左框中的按钮。他们有不一样的间距。
单选按钮可以使用斜体吗？（即Ke 等人而不是Ke等人）？

进口SYS 从PyQt4的进口QtGui，QtCore

class MainWindow(QtGui.QMainWindow): 
    def __init__(self): 
     QtGui.QMainWindow.__init__(self) 
     # title of the window 
     self.setWindowTitle('Segmentation Accuracy') 
     # fix window size 
     self.setFixedSize(400,200) 
     # status bar with initial message 
     self.statusBar().showMessage('ready') 


     # Layout 
     # contiene gli altri widget 
     cWidget = QtGui.QWidget(self) 
     grid = QtGui.QGridLayout(cWidget) 


     # Box Left 
     vBox_left = QtGui.QVBoxLayout() 
     vBox_left.setSpacing(2) #set spacing 

     Button_input1 = QtGui.QPushButton("Reference Polygons") 
     vBox_left.addWidget(Button_input1) 

     Button_input2 = QtGui.QPushButton("Segmented Polygons") 
     vBox_left.addWidget(Button_input2) 

     Button_output = QtGui.QPushButton("Save") 
     vBox_left.addWidget(Button_output) 

     Button_start = QtGui.QPushButton("Start") 
     Button_start.setCheckable(True) 

     vBox_left.addWidget(Button_input1) 
     vBox_left.addWidget(Button_input2) 
     vBox_left.addWidget(Button_output) 
     vBox_left.addWidget(Button_start) 

     # Box right 
     vBox_rigth = QtGui.QVBoxLayout() 
     vBox_rigth.setSpacing(10) #set spacing 
     ke = QtGui.QRadioButton("Ke et al.", cWidget) 
     pu = QtGui.QRadioButton("Pu et al.", cWidget) 
     clinton = QtGui.QRadioButton("Clinton et al.", cWidget) 
     ke.setChecked(True) 
     vBox_rigth.addWidget(ke) 
     vBox_rigth.addWidget(pu) 
     vBox_rigth.addWidget(clinton) 

     ke.setStatusTip("Ke et al., 2010. Remote Sensing of Environment, 114, pp. 1141-1154") 
     pu.setStatusTip("Pu et al., 2012. Remote Sensing of Environment, 124, pp. 516-533") 
     clinton.setStatusTip("Clinton et al., 2012. Remote Sensing of Environment, 124, pp. 516-533") 

     grid.addWidget(Button_input1, 0, 0) 
     grid.addWidget(Button_input2, 1, 0) 
     grid.addWidget(Button_output, 2, 0) 
     grid.addWidget(Button_start, 3, 0) 
     grid.addLayout(vBox_left, 0, 0) 
     grid.addLayout(vBox_rigth, 0, 1) 


     cWidget.setLayout(grid) 
     self.setCentralWidget(cWidget) 

def main(): 
    app = QtGui.QApplication(sys.argv) 
    main = MainWindow() 
    main.show()

您使用QGridLayout，并把Button_input1到单元格（0,0），并包含三个按键RAIDO进入细胞vBox_rigth布局（0,1 ）。他们被调整到相同的高度。这就是为什么你的四个按钮没有相同的间距。

grid = QtGui.QGridLayout(cWidget) 
    ...... 
    grid.addWidget(Button_input1, 0, 0) 
    ...... 
    grid.addLayout(vBox_rigth, 0, 1)

你不应该使用addWidget这些按钮添加到vBox_left两次。


    Button_input1 = QtGui.QPushButton("Reference Polygons") 
    vBox_left.addWidget(Button_input1) 

    Button_input2 = QtGui.QPushButton("Segmented Polygons") 
    vBox_left.addWidget(Button_input2) 

    Button_output = QtGui.QPushButton("Save") 
    vBox_left.addWidget(Button_output) 

    Button_start = QtGui.QPushButton("Start") 
    Button_start.setCheckable(True) 

    vBox_left.addWidget(Button_input1) 
    vBox_left.addWidget(Button_input2) 
    vBox_left.addWidget(Button_output) 
    vBox_left.addWidget(Button_start)

而且，这四个按钮已经被添加到QVBoxLayout vBox_left，那么你不应该将它们添加到grid。

grid.addWidget(Button_input1, 0, 0) 
    grid.addWidget(Button_input2, 1, 0) 
    grid.addWidget(Button_output, 2, 0) 
    grid.addWidget(Button_start, 3, 0)

您可以使用斜体显示小部件。您只需更改font属性。见http://doc.qt.digia.com/stable/qwidget.html#font-prop。
例如：

ke = QtGui.QRadioButton("Ke et al.", cWidget) 
    font = QtGui.QFont("Times", 10) 
    font.setItalic(True) 
    ke.setFont(font)

您还可以使用QLabel显示丰富的文本。例如：

ke_label = QtGui.QLabel("Ke <i>et al</i>.")

因此，最终__init__很可能是

def __init__(self): 
     QtGui.QMainWindow.__init__(self) 
     # title of the window 
     self.setWindowTitle('Segmentation Accuracy') 
     # fix window size 
     self.setFixedSize(400,200) 
     # status bar with initial message 
     self.statusBar().showMessage('ready') 


     # Layout 
     # contiene gli altri widget 
     cWidget = QtGui.QWidget(self) 
     grid = QtGui.QGridLayout(cWidget) 

     # Box Left 
     vBox_left = QtGui.QVBoxLayout() 
     vBox_left.setSpacing(2) #set spacing 

     Button_input1 = QtGui.QPushButton("Reference Polygons") 
     vBox_left.addWidget(Button_input1) 

     Button_input2 = QtGui.QPushButton("Segmented Polygons") 
     vBox_left.addWidget(Button_input2) 

     Button_output = QtGui.QPushButton("Save") 
     vBox_left.addWidget(Button_output) 

     Button_start = QtGui.QPushButton("Start") 
     Button_start.setCheckable(True) 

     # vBox_left.addWidget(Button_input1) 
     # vBox_left.addWidget(Button_input2) 
     # vBox_left.addWidget(Button_output) 
     vBox_left.addWidget(Button_start) 

     # Box right 
     vBox_right = QtGui.QVBoxLayout() 
     vBox_right.setSpacing(10) #set spacing 

     ke = QtGui.QRadioButton("", cWidget) 
     pu = QtGui.QRadioButton("", cWidget) 
     clinton = QtGui.QRadioButton("", cWidget) 
     ke.setChecked(True) 

     ke_label = QtGui.QLabel("Ke <i>et al</i>.", cWidget) 
     pu_label = QtGui.QLabel("Pu et al.", cWidget) 
     clinton_label = QtGui.QLabel("Clinton et al.", cWidget) 

     grid_right = QtGui.QGridLayout() 

     grid_right.addWidget(ke, 0, 0) 
     grid_right.addWidget(pu, 1, 0) 
     grid_right.addWidget(clinton, 2, 0) 
     grid_right.addWidget(ke_label, 0, 1) 
     grid_right.addWidget(pu_label, 1, 1) 
     grid_right.addWidget(clinton_label, 2, 1) 
     grid.addLayout(grid_right, 0, 1) 

     grid.setColumnStretch(0, 1) 
     grid.setColumnStretch(1, 1) 
     grid_right.setColumnStretch(1, 1) 

     ke.setStatusTip("Ke et al., 2010. Remote Sensing of Environment, 114, pp. 1141-1154") 
     pu.setStatusTip("Pu et al., 2012. Remote Sensing of Environment, 124, pp. 516-533") 
     clinton.setStatusTip("Clinton et al., 2012. Remote Sensing of Environment, 124, pp. 516-533") 


     ke_label.setStatusTip("Ke et al., 2010. Remote Sensing of Environment, 114, pp. 1141-1154") 
     pu_label.setStatusTip("Pu et al., 2012. Remote Sensing of Environment, 124, pp. 516-533") 
     clinton_label.setStatusTip("Clinton et al., 2012. Remote Sensing of Environment, 124, pp. 516-533") 

     # grid.addWidget(Button_input1, 0, 0) 
     # grid.addWidget(Button_input2, 1, 0) 
     # grid.addWidget(Button_output, 2, 0) 
     # grid.addWidget(Button_start, 3, 0) 
     grid.addLayout(vBox_left, 0, 0) 
     #grid.addLayout(vBox_right, 0, 1) 


     # cWidget.setLayout(grid) 
     self.setCentralWidget(cWidget)

感谢nymk斜体仅是为 “等人。” – 2013-03-12 18:01:32

@Gianni，你可以使用'QLabel'。例如，'label = QtGui.QLabel（“Ke et al.”）'。 – nymk 2013-03-12 18:12:40

对不起，我不知道在我的代码 – 2013-03-13 01:35:12
