Cursors in C#

Programming/WinForm / 2014. 11. 3. 03:29

A cursor in Windows is an icon that is displayed when you move a mouse, a pen, or a trackball. Usually, a different cursor image is displayed for different activity. For instance, the default cursor is different than a wait cursor.

Cursors may be different for different operating systems. Figure 1 displays some of the cursors available on machine loaded with Windows 7 operating system. As you can presume from Figure 1, the Default cursor is loaded most of the time, the AppStarting cursor is displayed when any application is starting and loading, and the Size cursors are loaded when you are resizing an application.

Windows Forms allows us to change this cursor image using the Cursor and its related classes and enumerations.

 
In this article, I will demonstrate how to apply and manage cursors in your Windows Forms applications.
 
Setting Cursor of Controls 

In Windows Forms, all Windows controls are derived from the Control class. The Control class has a Cursor property that represents a cursor respective to that control. That means, each control can have its own cursor. So the default cursor on a Form can be different than the default cursor on a child control on the same Form. The Cursor property is of type Cursors class. For example, the following code snippet sets default cursor of a Button and a ListBox control to Hand and No respectively. So when you rollover on button1 control, you will see hand cursor and when you rollover on listBox1 control, you will see a No cursor. You may use the same approach to define a cursor for any control. 

C# Code
 
button1.Cursor = Cursors.Hand;

listBox1.Cursor =Cursors.No;

VB.NET Code:
 

button1.Cursor = Cursors.Hand

listBox1.Cursor = Cursors.No

 
Cursors Class 

The Cursors class provides a set of cursors that can be used in Windows Forms. Each cursor is represented by a static property. Here is a list of cursors with brief description as described in MSDN.  
  • AppStarting - Gets the cursor that appears when an application starts.
  • Arrow - Gets the arrow cursor.
  • Cross - Gets the crosshair cursor.
  • Default - Gets the default cursor, which is usually an arrow cursor.
  • Hand - Gets the hand cursor, typically used when hovering over a Web link.
  • Help - Gets the Help cursor, which is a combination of an arrow and a question mark.
  • HSplit - Gets the cursor that appears when the mouse is positioned over a horizontal splitter bar.
  • IBeam - Gets the I-beam cursor, which is used to show where the text cursor appears when the mouse is clicked.
  • No - Gets the cursor that indicates that a particular region is invalid for the current operation.
  • NoMove2D - Gets the cursor that appears during wheel operations when the mouse is not moving, but the window can be scrolled in both a horizontal and vertical direction.
  • NoMoveHoriz - Gets the cursor that appears during wheel operations when the mouse is not moving, but the window can be scrolled in a horizontal direction.
  • NoMoveVert - Gets the cursor that appears during wheel operations when the mouse is not moving, but the window can be scrolled in a vertical direction.
  • PanEast - Gets the cursor that appears during wheel operations when the mouse is not moving, but the window can be scrolled in a horizontal direction.
  • PanNE - Gets the cursor that appears during wheel operations when the mouse is moving and the window is scrolling horizontally to the right.
  • PanNorth - Gets the cursor that appears during wheel operations when the mouse is moving and the window is scrolling horizontally and vertically upward and to the right.
  • PanNE - Gets the cursor that appears during wheel operations when the mouse is moving and the window is scrolling vertically in an upward direction.
  • PanNW - Gets the cursor that appears during wheel operations when the mouse is moving and the window is scrolling horizontally and vertically upward and to the left.
  • PanSE - Gets the cursor that appears during wheel operations when the mouse is moving and the window is scrolling horizontally and vertically downward and to the right.
  • PanSouth - Gets the cursor that appears during wheel operations when the mouse is moving and the window is scrolling vertically in a downward direction..
  • PanSW Gets the cursor that appears during wheel operations when the mouse is moving and the window is scrolling horizontally and vertically downward and to the left.
  • PanWest - Gets the cursor that appears during wheel operations when the mouse is moving and the window is scrolling horizontally to the left.
  • SizeAll - Gets the four-headed sizing cursor, which consists of four joined arrows that point north, south, east, and west.
  • SizeNESW - Gets the two-headed diagonal (northeast/southwest) sizing cursor
  • SizeNS - Gets the two-headed vertical (north/south) sizing cursor.
  • SizeNWSE - Gets the two-headed diagonal (northwest/southeast) sizing cursor.
  • SizeWE - Gets the two-headed horizontal (west/east) sizing cursor.
  • UpArrow - Gets the up arrow cursor, typically used to identify an insertion point.
  • VSplit - Gets the cursor that appears when the mouse is positioned over a vertical splitter bar.
  • WaitCursor - Gets the wait cursor, typically an hourglass shape.

Creating a Cursor 

Cursor is not a typical Windows Forms control. It is used as a helper control and does not have a user interface or design view. The Cursor class represents a cursor and it is created either using the Cursors class or load a cursor form a file. The following code snippet creates a cursor.

C# Code: 
 

Cursor cur = Cursors.WaitCursor;

this.Cursor = cur;

  
VB.NET Code:

 

Dim cur As Cursor = Cursors.WaitCursor

Me.Cursor = cur

Creating and Loading Custom Cursors 

Visual Studio allows you to create cursor (.cur) files. A cursor file is a bitmap file with .cur extension. To create a cursor file, right click on your project and select Add New Item menu item. After that, select Cursor File from the items. This action will add a default Cursor1.cur file. See Figure 2.

Figure 2

Once a cursor file is added, you will land in bitmap editor where you can change the bitmap using drawing tools as you can see in Figure 3.

Figure 3
 

Once you're done editing your file, save it. 

Now copy Cursor1.cur file to your Debug or Release folder where your executable file is stored. 

Once a file is saved, we can create a cursor from the cursor file using following code snippet.

C# Code:


this
.Cursor = new Cursor(Application.StartupPath +  "\\Cursor1.cur");  

VB.NET Code:
 

Me.Cursor = New Cursor(Application.StartupPath + "\Cursor1.cur") 

Current Cursor 

Cursor.Current static property gets and sets the current cursor. The following code snippet gets and sets the current cursor. 


C# Code:
 

this.Cursor = Cursor.Current; 

VB.NET Code:

 

Me.Cursor = Cursor.Current 

Move a Cursor Position 

The Position property of Cursor class is used to change the position of a cursor.

The following code snippet moves a cursor from its current position to 150 pixels less in both directions. 

C# Code:
 

Cursor.Position = new Point(Cursor.Position.X - 150, Cursor.Position.Y - 150); 


VB.NET Code:
 

Cursor.Position = New Point(Cursor.Position.X - 150, Cursor.Position.Y - 150) 

Show and Hide a Cursor 

The Hide and Show static methods of Cursor class are used to hide and show a cursor in a Windows application. The following code snippet hides and displays a cursor. 

C# Code:

 

Cursor.Hide();

Cursor.Show(); 

VB.NET Code:

 

Cursor.Hide()

Cursor.Show() 

Set and Change Current Cursor 

There are occasions when you need to change cursors based on some activity. For example, if you have a lengthy file copy or processing operation, you may want uses to wait and display a wait cursor for that. But once the processing is done, you change the cursor back the default cursor.

 
The following code snippet shows how to do the same. Before processing, set the cursor is set to the wait cursor and once the processing is done, the cursor is set to the default cursor. 

C# Code:
 

this.Cursor = Cursors.WaitCursor;

// Do something here

this.Cursor = Cursors.Default; 

VB.NET Code:

 

Me.Cursor = Cursors.WaitCursor

Me.Cursor = Cursors.Default

 

Summary 

In this article, I discussed how to create and user cursors in your Windows Forms applications. We also discussed how to create custom cursors and set other cursor properties.
