Description

Fields

	`FCurMin: double;`
Temporarily saved value of current minimum.

	`FMainCalcThread: TMainCalcThread;`
Pointer to the thread performing long-term method of the component. It is used for synchronization with main thread of the application. If this pointer is not Nil then displaying methods are called synchronously.

Methods

	`destructor Destroy; override;`

	`function CreateTaskObject: TFitTask; override;`

	`procedure AbortAsyncOper; override;`
Synchronous termination of long-term operation without calling termination method.

	`procedure ComputeBackgroundPointsDone; override;`

	`procedure ComputeCurveBoundsDone; override;`

	`procedure ComputeCurvePositionsDone; override;`

	`procedure Done; override;`

	`procedure ShowCurMin(Min: double); override;`
All methods must be called synchronously with main application thread, because they update UI. These methods must not call inherited ones, instead call synchronized counterparts of FMainCalcThread.

	`procedure ShowProfile; override;`

	`procedure StopAsyncOper; override;`
Asynchronous termination of long-term operation with calling termination method.

	`procedure ComputeBackgroundPointsDoneSync;`

	`procedure ComputeCurveBoundsDoneSync;`

	`procedure ComputeCurvePositionsDoneSync;`

	`procedure DestroyMainCalcThread;`
Waits for completion of the thread. Do not call from synchonized method, otherwise this will result in deadlock.

	`procedure DoneSync;`

	`procedure RecreateMainCalcThread(ATask: TThreadMethod; AAllDone: TThreadMethod); override;`

	`procedure ShowCurMinSync;`
These methods are called synchronously from the worker thread. They can't have parameters and call inherited methods to perform actual processing.

	`procedure ShowProfileSync;`
