Hi all.
I made a simple FlowChat Editor that creates rectangles and triangles and connects them to each other and shows the way from up to down. I can move this elements on screen too.
I am now trying to create a button to delete the element which I clicked. There is problem that I can delete MyTriangle objects, but I can't delete MyRectangle objects. It deletes but not object which I clicked. I delete from first object to last.
Here is my code:
if (deleteObj) {
if (rectsList.size() != 0) {
for (int i = 0; i < rectsList.size(); i++) {
MyRect rect = (MyRect) rectsList.get(i);
if (e.getX() <= rect.c.x + 50 && e.getX() >= rect.c.x - 50
&& e.getY() <= rect.c.y + 15 && e.getY() >= rect.c.y - 15) {
rectsList.remove(rect);
System.out.println("This is REctangle DELETED\n");
}
}
}
if (triangleList.size() != 0) {
for (int j = 0; j < triangleList.size(); j++) {
MyTriangle trian = (MyTriangle) triangleList.get(j);
if (e.getX() <= trian.c.x + 20 && e.getX() >= trian.c.x - 20
&& e.getY() <= trian.c.y + 20 && e.getY() >= trian.c.y - 20) {
triangleList.remove(trian);
System.out.println("This is Triangle Deleted\n");
}
}
}
Edit Here MyRectangle and MyTriangle classes
public class MyRect extends Ellipse2D.Double {
Point c;
Point in;
Point out;
int posX;
int posY;
int width = 100;
int height = 30;
int count;
public MyRect(Point center, Point input, Point output,int counter) {
c = center;
in = input;
out = output;
count=counter;
}
void drawMe(Graphics g) {
// in.x=c.x+20;
int posX = c.x;
int posY = c.y;
int posInX = in.x;
int posInY = in.y;
int posOutX = out.x;
int posOutY = out.y;
g.setColor(Color.MAGENTA);
g.drawString(" S "+count ,posX-5, posY+5);
g.setColor(Color.black);
g.drawRect(posX-50, posY-15, width, height);
g.setColor(Color.green);
g.drawRect(posInX-3, posInY-9, 6, 6);
g.setColor(Color.blue);
g.drawRect(posOutX-3, posOutY+3, 6, 6);
}
}
public class MyTriangle {
Point c;
Point in ;
Point outYES ;
Point outNO ;
int posX;
int posY;
int count;
public MyTriangle(Point center,Point input,Point outputYES,Point outputNO,int counter) {
c = center;
in = input;
outYES = outputYES;
outNO = outputNO;
count=counter;
}
void drawMe(Graphics g) {
int posX = c.x;
int posY = c.y;
int posInX=in.x;
int posInY=in.y;
int posOutYESX=outYES.x;
int posOutYESY=outYES.y;
int posOutNOX=outNO.x;
int posOutNOY=outNO.y;
int[] xPoints = {posX - 50, posX, posX + 50, posX};
int[] yPoints = {posY, posY - 30, posY, posY + 30};
g.setColor(Color.MAGENTA);
g.drawString(" T "+count,posX-5, posY+5);
g.setColor(Color.black);
g.drawPolygon(xPoints, yPoints, 4);
// draw input
g.setColor(Color.green);
g.drawRect(posInX-3,posInY-9, 6, 6);
g.setColor(Color.blue);
g.drawRect(posOutYESX-9,posOutYESY-3 , 6, 6);
g.setColor(Color.red);
g.drawRect(posOutNOX-3,posOutNOY+3 , 6, 6);
}
}
