Question

我编写了以下程序，该游戏为游戏工作者绘制了一个雷区

# -*- coding: utf-8 -*-
import mainw, sys
from PyQt4 import QtCore, QtGui

class WindowSapper(QtGui.QMainWindow):
    buttons=[]

    def __init__(self, parent=None):
        QtGui.QMainWindow.__init__(self,parent)
        self.ui=mainw.Ui_mainwin()
        self.ui.setupUi(self)
        for i in xrange(10):
            l=[]
            for j in xrange(10):
                b=QtGui.QPushButton()
                l.append(b)
                self.ui.gridLayout.addWidget(b, i, j, 1, 1)
            self.buttons.append(l)

def main():
    app=QtGui.QApplication(sys.argv)
    window=WindowSapper()
    window.show()
    sys.exit(app.exec_())

if __name__ == '__main__':
    main()

我也申请表单模块

        QtCore.QMetaObject.connectSlotsByName(mainwin)

    def retranslateUi(self, mainwin):
        mainwin.setWindowTitle(QtGui.QApplication.translate("mainwin", "Сапер", None, QtGui.QApplication.UnicodeUTF8))


class mainwin(QtGui.QMainWindow, Ui_mainwin):
    def __init__(self, parent=None, f=QtCore.Qt.WindowFlags()):
        QtGui.QMainWindow.__init__(self, parent, f)

        self.setupUi(self)

但是它没有达到我的预期：按钮没有完全填充GridLayout，其中有自由空间，也就是说，它们并没有完全填充单元格GridLayout。如何摆脱这些差距？

Answer 1

你看到大量间距的第一个原因实际上不是因为QGridLayout，而是因为没有任何东西限制你的布局对象使它们聚集在一起。您需要做的是在布局中添加一个拉伸以尽可能多地占用空间，迫使剩下的物品一起推进。

QGridLayout确实允许你向它添加延伸项，但我认为这会使网格导航更加复杂，因为你总是需要考虑该间隔行/列。因此，您可以将网格布局包装在垂直/水平布局中，并为这些布局添加间隔符。

执行此操作后，您会发现行之间留有少量空间。显然，这只是QGridLayout（see this other question）的一个已知事物。但是你可以使用按钮的大小，以及行和列的最小尺寸来实现它：

以下是一个示例（独立 - 不需要您的UI模块）

class WindowSapper(QtGui.QMainWindow):

    def __init__(self, parent=None):
        QtGui.QMainWindow.__init__(self,parent)
        self.resize(450,350)
        self.centralwidget = QtGui.QWidget()
        self.setCentralWidget(self.centralwidget)

        self.vLayout = QtGui.QVBoxLayout(self.centralwidget)
        self.hLayout = QtGui.QHBoxLayout()

        self.gridLayout = QtGui.QGridLayout()
        self.gridLayout.setSpacing(0)

        # center the grid with stretch on both sides
        self.hLayout.addStretch(1)
        self.hLayout.addLayout(self.gridLayout)
        self.hLayout.addStretch(1)

        self.vLayout.addLayout(self.hLayout)
        # push grid to the top of the window
        self.vLayout.addStretch(1)

        self.buttons = []
        for i in xrange(10):
            l=[]
            for j in xrange(10):
                b=QtGui.QPushButton()
                b.setFixedSize(40,30)
                l.append(b)
                self.gridLayout.addWidget(b, i, j)
                self.gridLayout.setColumnMinimumWidth(j, 40)
            self.buttons.append(l)
            self.gridLayout.setRowMinimumHeight(i, 26)
