RSS feeds, Rome Feeder Library, urls

in Contributed Library Questions • 2 years ago

Hi,

I'm working on creating an interactive timeline that includes the RSS feeds from several blogs. I've been experimenting with the Rome Feeder library to import the titles of each blog entry to the timeline. The examples that the author of the Rome Feeder library provided are very limited and I would like to know more about how to use it in other ways than they have presented. Simply put, my code thus far has included the timeline with squares that you can click to show different entries but I cannot get just one title from each blog post onto each one of the buttons. I have only been able to get the text to appear using

entry=feeder.next();

if(entry !=null)

text(entry.getTitle(),15,110,360,230);

on the second button.

entry=feeder.next(); is not what I want because all it does is draw all of the blog entry titles and then ends without displaying anything.

The other issue I have is how to grab these blog entries URLs and make them available when you click these blog titles, I haven't even attempted to do this yet because I haven't found any examples of someone doing this.

here is my code thus far

if this makes any sense please hook me up with some possible solutions

Button button1, button2, button3, button4, button5, button6, button7, button8, button9, button10;

int mode = 1;

feeder.sort(Feeder.PUBLISHED_DATE);

feeder.load("http://nabrgallery.wordpress.com/feed/");

feeder.setUpdateInterval(5*60*1000);

sorry i forgot the class code for Button that was included on a separate tab

class Button {

int x, y;

int size;

color baseGray;

color overGray;

color pressGray;

boolean over = false;

boolean pressed = false;

Button(int xp, int yp, int s, color b, color o, color p) {

x = xp;

y = yp;

size = s;

baseGray = b;

overGray = o;

pressGray = p;

}

void update() {

if ((mouseX >= x) && (mouseX <= x + size) &&

(mouseY >= y) && (mouseY <= y + size)) {

over = true;

} else {

over = false;

}

boolean press() {

if (over == true) {

pressed = true;

return true;

} else {

return false;

}

void release() {

pressed = false;

}

void display() {

if (pressed == true) {

fill(pressGray);

} else if (over == true) {

fill(overGray);

} else {

fill(baseGray);

}

stroke(255);

rect(x, y, size, size);

}

I just used rome in a similar project... To get the url of an entry, you have to use

entry.getLink()

To make the link clickable you have to implement something yourself in the mouseClicked() function to see which link (rectangle) has been clicked and then use the open function to start a browser passing the feed url as parameter.
