[英]How can the spacing between widgets in a QGridLayout remain fixed on window resize?
I am building an application in PyQT4
. 我正在
PyQT4
构建应用程序。 A principle part of this app will be to maintain a grid of widgets (sub classed from QLineEdit
widgets). 该应用程序的主要部分是维护小部件的网格(从
QLineEdit
小部件中分类)。 I am organizing the widgets into a QGridLayout
. 我正在将小部件组织到
QGridLayout
。
When I run the window, I get a grid organized just how I want, ie 当我运行窗口时,我得到的网格就是我想要的,即
However, the QGridLayout
has the property that it automatically pads the spacing between widgets when the window is resized, ie 但是,
QGridLayout
具有以下属性:当调整窗口大小时,它会自动QGridLayout
小部件之间的间距,即
I would love for the grid to have the same spacing between widgets, no matter how I resize the window. 无论我如何调整窗口大小,我都希望网格在小部件之间具有相同的间距。 I have looked and cannot seem to find how to accomplish this.
我已经看过,但似乎找不到解决方法。 I would have imagined something that fixes the spacing, but none of the likely sounding functions have this effect.
我本来可以想象固定间隔的东西,但是可能的探测功能都没有这种作用。
Here is a code snippet below, specifically just the part with the QGridLayout
. 这是下面的代码片段,特别是
QGridLayout
的部分。
class GridBlockTxtbx(QtGui.QWidget):
def __init__(self, blocks=5, spaces=5):
QtGui.QWidget.__init__(self)
self.dctn_txtbx = {}
self.blocks = blocks
self.spaces = spaces
# Create layout
layout = QtGui.QGridLayout()
# Set initial spacing between widgets to 2 pixels...
# I want this to be fixed on window resize!
layout.setSpacing(2)
# Function to load the widgets into the grid
GridBlockTxtbx._gen_block_txtbx_grid(layout, self.blocks,
self.spaces,
self.dctn_txtbx)
# Set the layout
self.setLayout(layout)
def _gen_block_txtbx_grid(layout, rows, cols, dctn):
for i in range(rows):
for j in range(cols):
blk = GridBlockTxtbx._gen_block_txtbx(idx=(i, j))
layout.addWidget(blk, i, j)
dctn[i, j] = blk
Add an expanding spacer to the last row/column of the grid-layout: 在网格布局的最后一行/列中添加一个扩展的间隔符:
vspacer = QtGui.QSpacerItem(
QtGui.QSizePolicy.Minimum, QtGui.QSizePolicy.Expanding)
layout.addItem(vspacer, last_row, 0, 1, -1)
hspacer = QtGui.QSpacerItem(
QtGui.QSizePolicy.Expanding, QtGui.QSizePolicy.Minimum)
layout.addItem(hspacer, 0, last_column, -1, 1)
