Layout: QGridLayout
===

| Column 1 | Column 2 |
| -------- | -------- |
| `addWidget(QWidget, int r, int c)` | 加入一個元件於 `(r, c)` 相對位置上 |
| `addWidget(QWidget, int r, int c, int rowspan, int columnspan)` | 加入一個元件於 `(r, c)` 相對位位置上，且可以對此元件做縮排。`rowspan` 為負數代表跨列 ( `columnspa` 則跨行)，請參考下面範例 |

import sys
from PyQt5.QtCore import *
from PyQt5.QtGui import *
from PyQt5.QtWidgets import *


def window():
    app = QApplication(sys.argv)
    win = QWidget()
    grid = QGridLayout()

    grid.addWidget(QPushButton("0,0"), 0, 0)
    grid.addWidget(QPushButton("0,1"), 0, 1)
    grid.addWidget(QPushButton("0,2"), 0, 2)
    
    # 第三個參數1: 維持一列
    # 第四個參數3: 延伸三行
    grid.addWidget(QPushButton("1,3"), 1, 0, 1, 3)    
    
    # 第三個參數-1: 橫跨列
    # 第四個參數 1: 維持一行
    grid.addWidget(QPushButton("2,0"), 2, 0, -1, 1)
    
    grid.addWidget(QPushButton("2,1"), 2, 1)
    grid.addWidget(QPushButton("2,2"), 2, 2)
    
    # 第三個參數-1: 橫跨列
    # 第四個參數-1: 橫跨行    
    grid.addWidget(QPushButton("3,1"), 3, 1, -1, -1)

    win.setLayout(grid)
    win.setWindowTitle("PyQt")
    win.show()
    sys.exit(app.exec_())


if __name__ == '__main__':
    window()
