我无法正确对齐图标和按钮文本。
我已经使用Designer生成了应用程序gui,默认情况下,它们显示如下:
我添加一些代码
win.pb_ejecutar.setStyleSheet("QPushButton { text-align: left; }")
我有这个
但是我需要的是,图标左对齐,文本中心对齐
我已经通过在名称中添加空格来做到这一点,但是我发现它不是很优雅
有人帮助我吗?谢谢

图标和文本之间的对齐方式相同,因此Qt样式表没有解决方案,因此另一种选择是使用QProxyStyle:
import sys
from PyQt5 import QtCore, QtGui, QtWidgets
class ProxyStyle(QtWidgets.QProxyStyle):
def drawControl(self, element, option, painter, widget=None):
if element == QtWidgets.QStyle.CE_PushButtonLabel:
icon = QtGui.QIcon(option.icon)
option.icon = QtGui.QIcon()
super(ProxyStyle, self).drawControl(element, option, painter, widget)
if element == QtWidgets.QStyle.CE_PushButtonLabel:
if not icon.isNull():
iconSpacing = 4
mode = (
QtGui.QIcon.Normal
if option.state & QtWidgets.QStyle.State_Enabled
else QtGui.QIcon.Disabled
)
if (
mode == QtGui.QIcon.Normal
and option.state & QtWidgets.QStyle.State_HasFocus
):
mode = QtGui.QIcon.Active
state = QtGui.QIcon.Off
if option.state & QtWidgets.QStyle.State_On:
state = QtGui.QIcon.On
window = widget.window().windowHandle() if widget is not None else None
pixmap = icon.pixmap(window, option.iconSize, mode, state)
pixmapWidth = pixmap.width() / pixmap.devicePixelRatio()
pixmapHeight = pixmap.height() / pixmap.devicePixelRatio()
iconRect = QtCore.QRect(
QtCore.QPoint(), QtCore.QSize(pixmapWidth, pixmapHeight)
)
iconRect.moveCenter(option.rect.center())
iconRect.moveLeft(option.rect.left() + iconSpacing)
iconRect = self.visualRect(option.direction, option.rect, iconRect)
iconRect.translate(
self.proxy().pixelMetric(
QtWidgets.QStyle.PM_ButtonShiftHorizontal, option, widget
),
self.proxy().pixelMetric(
QtWidgets.QStyle.PM_ButtonShiftVertical, option, widget
),
)
painter.drawPixmap(iconRect, pixmap)
if __name__ == "__main__":
app = QtWidgets.QApplication(sys.argv)
app.setStyle('fusion')
proxy_style = ProxyStyle(app.style())
app.setStyle(proxy_style)
w = QtWidgets.QWidget()
lay = QtWidgets.QVBoxLayout(w)
icons = [
app.style().standardIcon(standardIcon)
for standardIcon in (
QtWidgets.QStyle.SP_MediaPlay,
QtWidgets.QStyle.SP_MediaPause,
QtWidgets.QStyle.SP_MediaSeekBackward,
QtWidgets.QStyle.SP_MediaSeekForward,
)
]
for text, icon in zip("Play Pause Backward Forward".split(), (icons)):
button = QtWidgets.QPushButton(text)
button.setIcon(icon)
lay.addWidget(button)
w.show()
sys.exit(app.exec_())
