我正在制作一种图像查看器,在其中我们可以看到加载图像的直方图和hsv。代码按预期运行,除非我最大化窗口,否则所有QPushButtons都会放错位置。

答案 0 :(得分:0)
您正在使用布局和绝对定位(使用方法move
),这有点奇怪。您也不需要使用show()
那么多。它应该只在主窗口上调用。
如果要调整窗口大小,绝对定位通常不会很好。这是固定的。小部件将保持在相对于窗口左上角的相同位置。如果窗口变小,则会隐藏一些小部件,如果窗口变大,则不会使用新空间。
布局意味着灵活。您可以在垂直或水平线(QHBoxLayout
和QVBoxLayout
)或网格(QGridLayout
)上排列小部件。布局将填充所有可用空间:它们适用于任何窗口大小。
我建议您按照教程重新开始(一个好的是ZetCode Layout management in PyQt4)。尝试开始简单并逐步在布局中添加更多元素。在每个步骤测试以调整窗口大小以查看它是否按预期工作。
