<p>Could anyone help me out with a loop that will make the ellipses forming the flower grow. there are 5 ellipses acting as petals and the one center flower ellipse.</p> <pre><code>Stem myStem; Circle circles[]; float scaleFactor=0.5; void setup() { size(floor(400*scaleFactor), floor(800*scaleFactor)); myStem = new Stem(200,800); //mpoved this to setup, no need to recreate each frame circles = new Circle[6]; circles[0] = new Circle(0, -40, 50, 50); circles[1] = new Circle(0, -40, 50, 50); circles[2] = new Circle(0, -40, 50, 50); circles[3] = new Circle(0, -40, 50, 50); circles[4] = new Circle(0, -40, 50, 50); circles[5] = new Circle(0, 0, 50, 50); // also smooth only needs to be called once // unless ther is a noSmooth() somewhere // smooth(); } void draw() { float grow = 0; //translate(myStem.initalloX, myStem.initalloY); myStem.drawStem(); //set centre point if (frameCount>grow) { translate(myStem.initalloX, ((frameCount>250)?myStem.initalloY- 500:myStem.initalloY-(2*frameCount))); fill(170, 14, 24); // red for (int i = 0; i < circles.length-1; i++) { ellipse(circles[i].c1+grow, circles[i].c2+grow, circles[i].c3+grow, circles[i].c4+grow); rotate(radians(72)); } fill(14, 17, 170); // blue ellipse(circles[5].c1, circles[5].c2, circles[5].c3, circles[5].c4); } } class Stem { int initalloX=200; int initalloY=800; Stem(int tempInitalloX, int tempInitalloY) { initalloX = tempInitalloX; initalloY = tempInitalloY; } void drawStem() { background(#0DBADB); scale(scaleFactor, scaleFactor); stroke (12, 149, 11); fill (12, 149, 11); strokeWeight(10); line(initalloX, initalloY, initalloX, ((frameCount>250)?initalloY-500:initalloY-(2*frameCount))); //stem1 if (frameCount>101) { noStroke(); translate(initalloX, initalloY-200); scale(min((float)(frameCount-100)/100, 1), min((float)(frameCount-100)/100, 1)); beginShape(); vertex(0, 0); bezierVertex(-40, -5, -30, -40, -80, -20); bezierVertex(-47, -16, -52, 8, 0, 0); endShape(CLOSE); scale(1/min((float)(frameCount-100)/100, 1), 1/min((float)(frameCount-100)/100, 1)); translate(-initalloX, -(initalloY-200)); noStroke(); } //stem2 if (frameCount>151) { // noStroke(); translate(initalloX, initalloY-300); scale(-min((float)(frameCount-150)/150, 1), min((float)(frameCount-150)/150, 1)); beginShape(); vertex(0, 0); bezierVertex(-40, -5, -30, -40, -80, -20); bezierVertex(-47, -16, -52, 8, 0, 0); endShape(CLOSE); scale(-1/min((float)(frameCount-150)/150, 1), 1/min((float)(frameCount-150)/150, 1)); translate(-initalloX, -(initalloY-300)); } } } class Circle { int c1 = 0; int c2 = -40; float c3 = 50; float c4 = 50; Circle(int tc1, int tc2, float tc3, float tc4) { c1 = tc1; c2 = tc2; c3 = tc3; c4 = tc4; } } </code></pre> <p>This is a function in a program, and it is written in Processing. Thanks in advance for help/input!</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
