我发现有人提出了类似的问题,但没有答案或答案是替代解决方案。
我需要在 QComboBoxes 和 QListWidgets(在 PySide 中)中创建一个面包屑路径,并且我正在考虑将这些项目的文本设为粗体。但是,我很难找到有关如何实现这一目标的信息。
这就是我所拥有的:
# QComboBox
for server in servers:
if optionValue == 'top secret':
optionValue = server
else:
optionValue = '<b>' + server + '</b>'
self.comboBox_servers.addItem( optionValue, 'data to store for this QCombobox item' )
# QListWidgetItem
for folder in folders:
item = QtGui.QListWidgetItem()
if folder == 'top secret':
item.setText( '<b>' + folder + '</b>' )
else:
item.setText( folder )
iconSequenceFilepath = os.path.join( os.path.dirname(__file__), 'folder.png' )
item.setIcon( QtGui.QIcon(r'' + iconSequenceFilepath + ''))
item.setData( QtCore.Qt.UserRole, 'data …

我希望我的两个容器可以在VM主机之外的单独的特定IP地址(192.168.0.222
,192.168.0.227
)上使用,而不需要端口映射.这意味着我希望通过使用其IP来直接访问容器上的任何端口.我已经在VM主机外部的网络中运行的机器在192.168.0.1-192.168.0.221范围内.
现在可以使用Docker 1.10.0,如果是这样,怎么样?

我一直试图弄清楚这一点,没有运气,我已经阅读了以下问题和答案:
我正在创建一个名为Qt
