Mouse Movements

Mouse movements refer to various physical movements made by computer users on the screen using a mouse device. The mouse is used to move a cursor on the computer screen and perform actions like clicking, dragging, etc. Mouse movements provide computer users with an interactive interface. In the TRObject programming language, you can look at the following movements and purposes for using the event triggered when you move the mouse pointer over a component:

Feature	Use of	Definition
tbeOnMouseDown	MyForm.AddNewEvent(GestureImg, tbeOnMouseDown, 'onFormMouseDown');	It is an event triggered when a component (such as a button or an image) is clicked with the mouse. This event occurs when the mouse button is pressed.
tbeOnMouseUp	MyForm.AddNewEvent(GestureImg, tbeOnMouseUp, 'onFormMouseUp');	It is an event triggered when a component is released after being clicked with the mouse. This event represents the moment when the mouse button is released.
tbeOnMouseMove	MyForm.AddNewEvent(GestureImg, tbeOnMouseMove, 'onFormMouseMove');	It is an event triggered when you move the mouse pointer over a component. This event occurs when you move the mouse pointer.
clFormMousePosX	MyForm.clFormMousePosX
clSenderMousePosX	MyForm.clSenderMousePosX	It represents the X-coordinate of the mouse cursor over a component or form.
clFormMousePosY	MyForm.clFormMousePosY
clSenderMousePosY	MyForm.clSenderMousePosY	It represents the Y-coordinate of the mouse cursor over a component or form.

Example:

Basic Syntax

var
 myForm:TclForm;
 MouseLbl:TclLabel;
 GestureImg:TClImage;

Procedure onFormMouseMove;
begin

 MouseLbl.Text := IntToStr(MyForm.clFormMousePosX) + ','+ IntToStr(MyForm.clFormMousePosY);
 MouseLbl.Text := IntToStr(MyForm.clSenderMousePosX) + ','+ IntToStr(MyForm.clSenderMousePosY);
End;
procedure   onFormMouseDown;
begin

 MouseLbl.Text := IntToStr(MyForm.clFormMousePosX) + ','+ IntToStr(MyForm.clFormMousePosY);
 MouseLbl.Text := IntToStr(MyForm.clSenderMousePosX) + ','+ IntToStr(MyForm.clSenderMousePosY);
end;

procedure onFormMouseUp;
begin 
 MouseLbl.Text := IntToStr(MyForm.clFormMousePosX) + ','+ IntToStr(MyForm.clFormMousePosY);
 MouseLbl.Text := IntToStr(MyForm.clSenderMousePosX) + ','+ IntToStr(MyForm.clSenderMousePosY);
end; 

begin
 myForm := TClForm.Create(Self);

 MouseLbl := myForm.AddNewLabel(MyForm, 'MouseLbl','--');
 MouseLbl.Align := alTop;
 MouseLbl.Height := 20;

 GestureImg := myForm.AddNewImage(MyForm, 'GestureImg');
MyForm.setImage(GestureImg,'https://clomosy.com/demos/bg.png');
 GestureImg.Align := alCenter;
 GestureImg.Height := 300;
 GestureImg.Width := 300;

 MyForm.AddNewEvent(GestureImg, tbeOnMouseDown, 'onFormMouseDown'); 
 MyForm.AddNewEvent(GestureImg, tbeOnMouseUp, 'onFormMouseUp');
 MyForm.AddNewEvent(GestureImg, tbeOnMouseMove, 'onFormMouseMove');

 myForm.Run;

End;
