[Javacad-develop] Text on drawing

[Carl M. <car...@nt...>]

Hi all,
 
This is how I propose to add text to the drawing:
 
1)       Click the text tool
2)       Click on the drawing where you want the text to be placed
3)       A text box appears on the drawing
4)       User types the text then press Enter or clicks on the drawing
away from the text
5)       This places the text on the drawing without the textbox
6)       The text is draggable
7)       To change the font or colour - click the text then the font
tool to make the font dialog box to appear
8)       To change the text - double click the text will make the
textbox to reappear
 
Get back to me and tell me what you think.
 
 
Can you give me a rough idea of the layout of the panels? 
Is there a main drawing panel with drawing layers or views? 
Is there a hierarchical structure to how the elements sit on a drawing?
E.g. 
MainDrawing has many SheetGroup/LayerGroup/ViewGroup (whatever your
terminology)
SheetGroup has many Sheet (or View/Layer)
Sheet has many LineGroup, CircleGroup..etc.
LineGroup has many Line, Circle, Text.etc.
 
This is similar to how the SolidEdge class structure is laid out.
SolidEdge is a 2D/3D package with the ability to program macros in VB
using its API - things like writing a macro to calculate the area of an
object when clicking inside its boundary. Many of my ideas will come
from that package.
 
 
Bug on the main GUI - When I call up a new drawing the menu bar
disappears.
 
Do you intend the application to have a multi document interface (MDI) -
there is a good example of this at SourceForge called JHotDraw -
http://sourceforge.net/projects/jhotdraw/ 
 
Bye for now
Carl

[powergis <pow...@si...>]

hi, guys,

Thanks Wang and Ella Lynoure Rajamaki for your kindly helps.

Ant is indeed odd to me.

Now I have installed ANT 1.4.1 from the following website:
http://jakarta.apache.org/builds/jakarta-ant/release/v1.4.1/bin/jakarta-ant-1.4.1-bin.zip

In detail, I have install also set the environment variables, such as ANT_HOME, JAVA_HOME and ClassPath as follows.
#######################################################
ClassPath=.;c:\jdk1.2.2\lib\tools.jar;C:\ant\lib\ant.jar;C:\ant\lib\jaxp.jar;C:\ant\lib\parser.jar;C:\ant\lib\crimson.jar;
#######################################################

Now, I think I can use "ant JCad-compile" to compile it. Some errors occur as follows.
#######################################################

I wonder whether the version of ANT cause the error.
BTW, how can I use the PGP Signatures? WHether the errors are caused from the PGP Signatures?

Waiting for your helps. Thx a lot!

[Javacad-develop] Up to date ChangeLog anywhere?

[Ella L. R. <ly...@tu...>]

Is there a ChangeLog or other up to date listing of changes in the code
somewhere? It's hard to see the big picture from log entries.

From the current ChangeLog file one would assume nothing has happened
since last release, but that is not the case...

Install is slightly misleading: if you got the source from CVS, you do
need to compile it first before running. As the INSTALL says, you need ant
for this. After you have ant installed, it's simply a matter of doing
first
ant jcad-compile

and then
ant jcad-run

Using ant to run things seemed a bit odd to me but it does probably have
it's advantages.

> Can you do me a favor to help me out? Thanks in advance.

Try using ant as describe above. If you run into further problems, feel
free to ask.

(I'm not actually involved in the project, but I don't mind helping when I
can.)

[Javacad-develop] I cannot run the JCad. Pls do me a favor

[powergis <pow...@si...>]

Hi, guys,

I'm a beginner of JAVA developing.
I download the JCad source codes and try to test. Now some problems occur.

First, I have read such files carefully:
       README
       INSTALL
       DOCS/hacking.txt
       DOCS/userguide.txt
But I cannot find the file "JCad.jar". So I have to compile the sourcecodes on myself.

First step, I compile them with JDK 1.2.2. I found that SAX classes are missing, so I download SAX2.0 from the official SAX website. Henceforth, I've got the JCad.class.

Second, I try to run it as follows:
##########################################################
C:\JCad>java org/jcad/JCad/JCad
uncaught exception: java.lang.NullPointerException
java.lang.NullPointerException
        at org.jcad.JCad.JCad.main(JCad.java:224)
##########################################################

I found that JCad.java:224 is as follows:
      frame.getContentPane().add("Center", new JCad());

Can you do me a favor to help me out? Thanks in advance.

From what I remember of my download, the anonymous password is empty. So
just hit enter when you are asked for the password.

If that doesn't do it, you tell if WinCVS gives any warnings or
errors when you are trying to login.

Hi,

I'm interested in javacad.
I want to download the code for testing.
But I donnot know the password of CVS.

I use WinCVS send the command as follows.

cvs -d :pserver:ano...@cv...:/cvsroot/javacad login

But I donnot know the password.
Can you do me a favor?

Thanks in advance.
