GetDiskSize Event
Fires when the OS needs to retrieve the size of the virtual disk.
Syntax
class CBDiskGetDiskSizeEventParams { public: qint64 Size(); void SetSize(qint64 lSize); int ResultCode(); void SetResultCode(int iResultCode); int EventRetVal(); void SetEventRetVal(int iRetVal); };
// To handle, connect one or more slots to this signal. void GetDiskSize(CBDiskGetDiskSizeEventParams *e);
// Or, subclass CBDisk and override this emitter function. virtual int FireGetDiskSize(CBDiskGetDiskSizeEventParams *e) {...}
Remarks
This event fires when the OS needs to retrieve the size of the virtual disk.
To handle this event properly, applications must set Size to reflect the size in bytes of the block of data associated with the virtual disk.
The ResultCode parameter will always be 0 when the event is fired. If the event cannot be handled in a "successful" manner for some reason (e.g., a resource isn't available, security checks failed, etc.), set it to a non-zero value to report an appropriate error. Please refer to the Error Reporting and Handling topic for more information.
