Details
All the code for the Backup File Management is contained in a new class BackupFiles.
The daily and overview menus are responsible for creating an instance of BackupFiles and calling a method when the Backup button is activated.
The backup files are created/read using loadSettings and saveSettings methods in gGraphView. The settings filename name is the only parameter. There are no changes made to gGraphView.
User Descriptions
The user description is a set of characters up to a maximum length of 60 characters.
It must be a single line.
White white space is trimmed from string.
Cut and paste work with QT so multi-line strings can be added. The first line of the multi-line string is used.
Empty descriptions (all white space) will not change the previous description.
Backup Files
The file name used is GraphTitle.backupNNN.
where GraphTitle is either "daily" or "overview"
and NNN is a 3 digit decimal integer - ( 0 <= NNN < limit ).
This description is NOT a part the real file name but is stored as name value pair (filename : description). This allows for the description independent from the file name.
Backup descriptions are saved in an descriptions.txt file where the backup file name is associated with the user description.
Each backup has a single line entry in the form
backupNNN:<Description>. The Description can use unicode characters.
backup name examples:
- backup001:My Primary layout - backup002:已成功删除 عذرا ، لا يمكن تحديد موقع ملف. 删除 - backup004:/ ? ~ : any character
Currently, the same description can be used for multiple backups.
If the description file is corrupted then the backup file name will be used.
"eg. backup002"
file name examples
- overview.backup008.shg file name used for 1st backup file - overview.descriptions.txt file name used descriptions.
