One is to pass through a Rectangle object and Pen and the other is to create an instance of a Rectangle object and pass that through along with the Pen. There are two ways to use the DrawRectangle() method. The above code, when compiled and executed will result in the form appearing as follows:įor the purposes of drawing rectangles and squares in C# the GraphicsObject provides the DrawRectangle() method. For example, to draw a line from co-ordinates (20, 20) to (200, 210) on our sample form: private void Form1_Paint(object sender, PaintEventArgs e) This method takes a pre-instantiated Pen object and two sets of x and y co-ordinates (the start and end points of the line) as arguments. Lines are drawn in C# using the DrawLine() method of the Graphics Object. Now that we have a Paint() event handler, a Graphics Object and Pen we can now begin to draw. Properties such as the color and width may similarly be changed after a Pen has been created: myPen.DashStyle = .DashDotDot For example, the DashStyle property can be modified to change the style of line (i.e Dash, DashDot, DashDotDot, Dot, Solid or Custom). Once a Pen object has been created other properties may be changed. Where variable_name is the name to be assigned to the Pen object, color is the color of the pen and width is the width of the lines to be drawn by the pen.įor example, we can create red pen that is 5 pixels wide as follows: private void Form1_Paint(object sender, PaintEventArgs e) Pen variable_name = new Pen ( color, width) A Pen object may be quite easily created as follows: Now that we have a Graphic Object we need a Pen with which to draw.Ī Graphics Object is of little use without a Pen object with which to draw (much as a sheet of paper is no good without a pen or pencil). For example, a Graphics Object can be created on our Form called Form1 by calling CreateGraphics() method as follows in the Paint() method: private void Form1_Paint(object sender, PaintEventArgs e) Graphics Objects are created by calling the CreateGraphics() method of the component on which the drawing is to performed.
CTRL PAINT VS DRAW A BOX CODE
Double click the Paint event to display the code editing page.
With the new project created select the Form in the design area and click on the lightning bolt at the top of the Properties panel to list the events available for the Form.
The first step in this tutorial is to create a new Visual Studio project called CSharpGraphics. We will look at redrawing the graphics in the Paint() event in this chapter and Using Bitmaps for Persistent Graphics in C# in the next chapter. One is to repeatedly perform the drawing in the Paint() event handler of the control (which is triggered whenever the component needs to be redrawn), or to perform the drawing on a bitmap image in memory and then transfer that image to the component whenever the Paint() event is triggered. Two mechanisms are available for achieving this. In fact what will happen is that as soon as the window is minimized or obscured by another window the graphics will be erased.įor this reason, steps need to be taken to ensure that any graphics are persistent. Lets us see what MS Paint supports.An important point to note before proceeding with is chapter is that simply creating a Graphics Object for a component and then drawing on that component does not create persistent graphics.
CTRL PAINT VS DRAW A BOX WINDOWS
Windows in general has specific functions associated with each function key ( F1 through F12 keys). I find it really useful when my mouse malfunctions due to whatever reasons.Įquivalent to right-clicking on the title bar If you simply press the Alt key you will be shown few key tips (as shown in the image) using which you can navigate the interface and its tools. Here are few images showing the grid lines, ruler, resize and skew dialog and the image properties dialog. While most of these combinations are common to many applications, there are some that you may find new and unique. We are sure you’d be smart enough to figure that out. However, there could be a few differences in actions or key combinations. Ideally, they should work on other versions as well. These shortcuts have been tried and tested on Windows 7.
We are referring to keyboard shortcuts and we feel that if mastered, they can really enhance your efficiency with MS Paint too. While those tips are amazing, there is one more thing that comes in handy when you are using MS Paint or rather, any other tool. Recently we wrote about some tricks that can help you in using MS Paint productively.
