PySide.QtNetwork.QUrlInfo class stores information about URLs.
The information about a URL that can be retrieved includes PySide.QtNetwork.QUrlInfo.name() , PySide.QtNetwork.QUrlInfo.permissions() , PySide.QtNetwork.QUrlInfo.owner() , PySide.QtNetwork.QUrlInfo.group() , PySide.QtNetwork.QUrlInfo.size() , PySide.QtNetwork.QUrlInfo.lastModified() , PySide.QtNetwork.QUrlInfo.lastRead() , PySide.QtNetwork.QUrlInfo.isDir() , PySide.QtNetwork.QUrlInfo.isFile() , PySide.QtNetwork.QUrlInfo.isSymLink() , PySide.QtNetwork.QUrlInfo.isWritable() , PySide.QtNetwork.QUrlInfo.isReadable() and PySide.QtNetwork.QUrlInfo.isExecutable() .
You can create your own PySide.QtNetwork.QUrlInfo objects passing in all the relevant information in the constructor, and you can modify a PySide.QtNetwork.QUrlInfo ; for each getter mentioned above there is an equivalent setter. Note that setting values does not affect the underlying resource that the PySide.QtNetwork.QUrlInfo provides information about; for example if you call setWritable(true) on a read-only resource the only thing changed is the PySide.QtNetwork.QUrlInfo object, not the resource.

PySide.QtCore.QUrl FTP Example
| 参数： |
|
|---|
Constructs an invalid PySide.QtNetwork.QUrlInfo object with default values.
构造 PySide.QtNetwork.QUrlInfo object by specifying all the URL's information.
The information that is passed is the name , file permissions , owner and group and the file's size . Also passed is the lastModified date/time and the lastRead date/time. Flags are also passed, specifically, isDir , isFile , isSymLink , isWritable , isReadable and isExecutable .

Copy constructor, copies ui to this URL info object.
This enum is used by the PySide.QtNetwork.QUrlInfo.permissions() function to report the permissions of a file.

| 参数： |
|
|---|---|
| 返回类型： |
PySide.QtCore.bool |
返回 true 若 i1 equals to i2 ; otherwise returns false. The objects are compared by the value, which is specified by sortBy . This must be one of QDir.Name , QDir.Time or QDir.Size .
| 参数： |
|
|---|---|
| 返回类型： |
PySide.QtCore.bool |
返回 true 若 i1 大于 i2 ; otherwise returns false. The objects are compared by the value, which is specified by sortBy . This must be one of QDir.Name , QDir.Time or QDir.Size .
| 返回类型： | unicode |
|---|
Returns the group of the URL.
| 返回类型： | PySide.QtCore.bool |
|---|
Returns true if the URL is a directory; otherwise returns false.
| 返回类型： | PySide.QtCore.bool |

Returns true if the URL is executable; otherwise returns false.
| 返回类型： | PySide.QtCore.bool |
|---|
Returns true if the URL is a file; otherwise returns false.
| 返回类型： | PySide.QtCore.bool |
|---|
Returns true if the URL is readable; otherwise returns false.
| 返回类型： | PySide.QtCore.bool |
|---|
Returns true if the URL is a symbolic link; otherwise returns false.
| 返回类型： | PySide.QtCore.bool |
|---|
Returns true if the URL info is valid; otherwise returns false. Valid means that the PySide.QtNetwork.QUrlInfo contains real information.
You should always check if the URL info is valid before relying on the values.
| 返回类型： | PySide.QtCore.bool |

Returns true if the URL is writable; otherwise returns false.
| 返回类型： | PySide.QtCore.QDateTime |
|---|
Returns the last modification date of the URL.
| 返回类型： | PySide.QtCore.QDateTime |
|---|
Returns the date when the URL was last read.
| 参数： |
|
|---|---|
| 返回类型： |
PySide.QtCore.bool |
返回 true 若 i1 is less than i2 ; otherwise returns false. The objects are compared by the value, which is specified by sortBy . This must be one of QDir.Name , QDir.Time or QDir.Size .
| 返回类型： | unicode |
|---|
Returns the file name of the URL.
| 参数： | i – PySide.QtNetwork.QUrlInfo |
|---|---|
| 返回类型： | PySide.QtCore.bool |
返回 true，若此 PySide.QtNetwork.QUrlInfo is not equal to other ；否则返回 false。
| 参数： | i – PySide.QtNetwork.QUrlInfo |
|---|---|
