Point PShapes not visible

[3 Replies]

I'm trying to create and draw a PShape which contains one (or more) point.

when I try to render it "shape(pointShape, x, y);" with P2D renderer nothing is visible. (in Processing 2.0 and 2.1)

I tried to change the stroke and strokeWeight, but nothing gets drawn.

Does someone know, what I'm doing wrong. (Other Shapes are no Problem).

// first try:
1. PShape pointShape;
3. pointShape = createShape(POINT, 0, 0);
4. pointShape.setStroke(255);
5. pointShape.setStrokeWeight(5);
6. pointShape.setFill(255);
8. background(0);
9. shape(pointShape, width/2, height/2);
// second try:
1. PShape pointShape;
3. pointShape = createShape();
4. pointShape.beginShape(POINTS);
5. pointShape.stroke(255);
6. pointShape.strokeWeight(3);
7. pointShape.vertex(0, 0);
8. pointShape.endShape();
10. background(0);
11. shape(pointShape, width/2, height/2);

controlP5 - styling TextField

Hi,
I have got two questions on styling a controlP5 Textfield:

1. I s it possible to change the border color of a controlP5.Controller.Textfield ?

I can change the border color on focus with .setColorActive("color") but cannot find a similar methode for the "ColorPassive" (.setColor(color) sets the textColor)

can I extend the Textfield und override the color (does someone know which methode to override?)

2. I'd like to set a "padding-left" to the Textfield. I didn't find a methode either.

my workaround is adding a " " to the front of the String.

Would be great, if someone has a solution (especially for the borderColor).

Thanks

The the set controlP5.Controller.setLabelVisible(false) method seems not to work with Textfield Labels. (Testet in controlP5 2.0.3 & 2.0.4)
Is there a possibility to format and set the position of the Label?

I'm using proHtml to find the image tags of a website (guardian.co.uk). that works fine.
the problem is, i get the the Strings lowercase. But I need the src-atrribute in the origianl form (mixedCase) to load the images in my application. does anybody know how i get the right src-attribute?

(to get my application work, I worte a parser my own, but its very slowly.
I would prefer to use the much faster proHtml lib)

Serial library in Eclipse

hello,

i'm trying for the last hours to get the serial library running in eclipse (Eclipse IDE for Java Developers Version 1.2.1.20090918) on macbookpro mac osx 10.6.4 to get connected to my arduino board.

what i've done yet:

i imported the
- core.jar
- serial.jar
- RXTXcomm.jar
copied librxtxSerial.jnilib to MacintoshHD/Library/Java/Extensions/
linked RXTXcomm.jar to librxtxSerial.jnilib (by choosing RXTXcomm.jar - properties - Native library: Location path: /Library/Java/Extensions)

when i run the programm, i get this error:

java.lang.UnsatisfiedLinkError: /Library/Java/Extensions/librxtxSerial.jnilib: no suitable image found. Did find: /Library/Java/Extensions/librxtxSerial.jnilib: no matching architecture in universal wrapper thrown while loading gnu.io.RXTXCommDriver

    at java.lang.Thread.run(Thread.java:637)

my second try was to use the arduino library with the Arduino Firmata.
same imports und link to librxtxSerial.jnilib

when i run the programm, this window pops up and asks me to chongure gnu.io.rxtx.properties

Now i don't know what to do.

when i just close the window i get the following exception:
/System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home/lib/gnu.io.rxtx.SerialPorts
IOException!

can anybody help me please?
manuel
