Post subject:  System info plugin
Hi,

I was busy working on the system info plugin... I tried to implement a cpu monitor much like the task manager. I now created a class derived from LCDBitmap that created a line graph with veriable step rates, size selectable grid in the background and custom sized graphs... I am almost finished with this. I think this might be a usefull class to include in the display items unit instead of just in one plugin. This will allow more plugins to display graphs of different stats in there plugins? Will mail it to henri when done. Hope its usefull :?:

Sounds good. Or should I say looks good as I just checked the plugin you sent me and the graph looks very nice. :)

And you're right that it would be nice to have displayitem for graphs that would allow graphing any numerical variables. In fact I have been planning this for a long time but haven't started it yet as there have been so many other things. But now you have already done the graphing code, only need to add it as new displayitem. :)

I have also mailed the new version for you. The update can be configured to have a grid in different sizes or have a border too. The step size also looks better if it is 4 pixels and not 8. Hope you can use it!

This is correct. This can then become a plugin on its own. You can then monitor anything you want. From hard drive write cycles to cpu usage...

Hi,

I updated the system info plugin. I added a new unit called hdrive, which does some general hard drive check (eg. total space, free space, etc). I changed Graph to BarGraph and added a PieGraph. I also made new plugin text to display a string that just tells you how much space you have left on a hard drive. I then made a pluginimage to display the pie graph of space left of the c drive and the d drive!!

Please note that at this state I check if the drive is fixed. If not, it doesn't do anything!!! So if the drive is removable, it will not display info yet. If the pie graph is shown of a drive that doesn't exist or are removable. It will show a 0% free graph!! This will be fixed soon.

I mailed this to henri, after his aproval, it will hopefully be released :?

If i remember well, cdrom drive arent removable driver, how do you manage them?
:( no removable drive :'(

Yes cdrom is not a fixed drive and I do not support it yet...

The GetDriveType function returns DRIVE_CDROM if the drive is a cdrom and DRIVE_FIXED if the drive is a fixed hard drive... I only accept DRIVE_FIXED for now. Will update it soon...

The following new exports for the Sysinfo plugin:

Code:
8:50:55:990  Plugin variable: ID:"SysInfo.CDrive" Name:C: Drive Type: 0 2
8:50:55:990  Plugin variable: ID:"SysInfo.DDrive" Name:D: Drive Type: 0 3
8:50:55:990  Plugin image: ID:"SysInfo.CHDDgraph" Name: C: Hard Drive graph 1
8:50:55:990  Plugin image: ID:"SysInfo.DHDDgraph" Name: D: Hard Drive graph 2


I have only added support for drive c and d so far... Will add more... Whould have been nice if i could have said "SysInfo.HDDgraph(0)" so that it takes varaibles???
