我怎么能在循环中创建一个按钮

Question

我正在尝试在循环中创建一个简单的按钮表，但我的代码不起作用。没有错误，但我没有看到执行结果。

import sys
from PyQt4 import QtGui, QtCore

names = ['X+', 'X-', 'Y+',\
        'Y-', 'Z+', 'Z-',\
        'A1+', 'A1-', 'A2+',\
        'A2-', 'A3+', 'A3-',\
        'Hand']

pos = [(50, 100), (200, 100), (50, 200),\
        (200,200), (50, 300), (200,300),\
        (370, 100), (520, 100), (370, 200),\
        (520, 200), (370, 300), (520, 300),\
        (50, 400)]

size = [(74, 74), (74, 74), (74, 74),\
        (74, 74), (74, 74), (74, 74),\
        (74, 74), (74, 74), (74, 74),\
        (74, 74), (74, 74), (74, 74),\
        (226, 74)]

class Window(QtGui.QMainWindow):

    ...........

    def createButtons(self):  
        index = 0
        self.buttons = []

        for i in names:
            self.buttons.append(index)
            self.buttons[index] = QtGui.QPushButton(self)
            self.buttons[index].setText(i)
            self.buttons[index].setGeometry(pos[index][0], pos[index][1], size[index][0], size[index][1])
            index += 1

def runApp():
    app = QtGui.QApplication(sys.argv)
    gui = Window()
    gui.createButtons()
    gui.show()
    sys.exit(app.exec_())

runApp()

你能帮帮我吗？ 名字 - 名单， pos - 位置列表[x，y]， size - w和h的列表。

您只需更改尺寸即可看到按钮。您必须使用resize()

import sys
from PyQt4 import QtGui, QtCore

names = ['X+', 'X-', 'Y+',\
        'Y-', 'Z+', 'Z-',\
        'A1+', 'A1-', 'A2+',\
        'A2-', 'A3+', 'A3-',\
        'Hand']

pos = [(50, 100), (200, 100), (50, 200),\
        (200,200), (50, 300), (200,300),\
        (370, 100), (520, 100), (370, 200),\
        (520, 200), (370, 300), (520, 300),\
        (50, 400)]

size = [(74, 74), (74, 74), (74, 74),\
        (74, 74), (74, 74), (74, 74),\
        (74, 74), (74, 74), (74, 74),\
        (74, 74), (74, 74), (74, 74),\
        (226, 74)]

class Window(QtGui.QMainWindow):
    def __init__(self, parent=None):
        super(Window, self).__init__(parent=parent)

    def createButtons(self):  
        index = 0
        self.buttons = []

        for i in names:
            self.buttons.append(index)
            self.buttons[index] = QtGui.QPushButton(self)
            self.buttons[index].setText(i)
            self.buttons[index].setGeometry(pos[index][0], pos[index][1], size[index][0], size[index][1])
            index += 1

        self.resize(650, 500)

def runApp():
    app = QtGui.QApplication(sys.argv)
    gui = Window()
    gui.createButtons()
    gui.show()
    sys.exit(app.exec_())

runApp()
