[Qt-interest] why QTemporaryFile::open is not allowing specify flags?

[Malyushytsky, Alex]

>> Firstly, temporary files aren't meant to be used/edited by the user.

There is no reason to assume temporary file context will not be read or even modified by user directly or indirectly.
Logically temporary file is just a 'temporary' file and user may be accessed within it life cycle.

For example log file may be a temporary file by design.
In my case this file contains input to other computation tool which will be started and monitored by my application.
And advanced user of such tool may want to see and modify it in editor of his choice after this information is generated but before this tool is invoked.

There is no assumptions can or should be done about nature of the file. 
The only special feature about this class - it is guarantee file not to survive longer than application ( QTemporaryFile object ) which opens it.


>> Secondly, doesn't setTextModeEnabled() solve the problem?

It does fix the need to override QTemporaryFile which I missed, 
but does not explain why it can't be done anymore with open.

Firstly, temporary files aren't meant to be used/edited by the user.

Secondly, doesn't setTextModeEnabled() solve the problem?
