I have trouble drawing a triangle with the draw(Graphics g)
method in Java.
I can draw a rectangle like so:
public void draw(Graphics g) {
g.setColor(colorFill);
g.fillRect(p.x, p.y, width, height);
g.setColor(colorBorder);
g.drawRect(p.x, p.y, width, height);
drawHandles(g);
Where p represents "the top left corner of the shapes". How would I draw the triangle in the same manner?
Could someone give me an example for a standard triangle?
There is not a drawTriangle method neither in Graphics nor Graphics2D. You need to do it by yourself. You can draw three lines using the drawLine
method or use one these methods:
These methods work with polygons. You may change the prefix draw
to fill
when you want to fill the polygon defined by the point set. I inserted the documentation links. Take a look to learn how to use them.
There is the GeneralPath class too. It can be used with Graphics2D, which is capable to draw Shapes. Take a look:
