swing - GridBagLayouts in GridLayout -

-

trying build gui in swing:

enter image description here

in mainframe set gridlayout achieve 1 row, 2 columns:

setlayout(new gridlayout(1, 2));

in left column figures need gridbaglayout in right column. normal gridlayout doesn't work anymore because want different sizes of each row. left column tried this:

gridbagconstraints gbc = new gridbagconstraints();      mappanel = new mappanel(map);     gbc.fill = gridbagconstraints.both;     gbc.gridx = 0;     gbc.gridy = 0;     gbc.gridheight = 10;     add(mappanel, gbc);      controlpanel = new jpanel();     controlpanel.add(new jbutton("test"));     controlpanel.add(new jbutton("test 2"));     controlpanel.add(new jbutton("test 3"));     controlpanel.add(new jbutton("test 4"));     gbc.fill = gridbagconstraints.both;     gbc.gridx = 0;     gbc.gridy = 1;     gbc.gridheight = 1;     add(controlpanel, gbc);      logpanel = new logpanel();     gbc.fill = gridbagconstraints.both;     gbc.gridx = 0;     gbc.gridy = 2;     gbc.gridheight = gridbagconstraints.remainder;     add(logpanel, gbc);

this result in "packed together" in left column. won't expand 100% height , 50% width column has. how can achieve gui in picture?

thanks!

look @ jnodelayout. rectnode need.

import java.awt.borderlayout; import java.awt.color; import java.awt.container; import java.awt.geom.rectangle2d;  import javax.swing.jframe; import javax.swing.jpanel; import javax.swing.border.emptyborder; import javax.swing.border.lineborder;  import com.smartg.swing.layout.jnodelayout; import com.smartg.swing.layout.layoutnode.rectnode;  public class rectnodedemo {      public static void main(string[] args) {          string rootname = "root";         rectnode root = new rectnode(rootname);         jnodelayout layout = new jnodelayout(root);         layout.sethgap(1);         layout.setvgap(1);           jpanel target = new jpanel();         target.setborder(new emptyborder(10, 10, 10, 10));          target.setlayout(layout);          addpanel(target, root, new rectangle2d.double(0, 0, .5, .5));         addpanel(target, root, new rectangle2d.double(0, .5, .5, .1));         addpanel(target, root, new rectangle2d.double(0, .6, .5, .4));            addpanel(target, root, new rectangle2d.double(.5, 0, .5, .9));         addpanel(target, root, new rectangle2d.double(.5, .9, .5, .1));          layout.syncnodes();          jframe frame = new jframe();          container contentpane = frame.getcontentpane();         contentpane.setlayout(new borderlayout());         contentpane.add(target, borderlayout.center);         frame.pack();         frame.setvisible(true);     }      static void addpanel(jpanel target, rectnode node, rectangle2d r) {         jpanel p = new jpanel();         target.add(p);         p.setborder(new lineborder(color.black, 1));         node.add(p, r);     } }

i need hash algorithm produces 64-bit hash code ( long ) fewer collisions string.gethashcode() , fast (no expensive calls cryptographic functions). here's implementation of fnv still shows 3% of collisions after testing 2 million random strings. need number way lower. void main() { const string chars = "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz!#@$%^&*()_+}{\":?><,./;'[]0123456789\\"; const int n = 2000000; var random = new random(); var hashes = new hashset<long>(); int collisions = 0; for(int = 0; < n; i++) { var len = random.next(chars.length); var str = new char[len]; (int j = 0; j < len; j++) { str[j] = chars[random.next(chars.length)]; } var s = new string(str); if(!hashes.add(get64bithash( s ))) collisions++; } console.writeline("collision percentage after " + n + " random strings: " + ((doubl

i'm newbie trying out ml/dbn in python (3.4) under pycharm (comm.ed 4.5). following definition def make_thetas(xmin,xmax,n): xs = np.linespace(xmin,xmax,n) widths = (xs[1:] - xs[:-1])/2.0 thetas = xs[:-1] + widths return thetas throws error "class 'tuple' not define ' sub ', '-' operator cannot used on instance" on - operator on third line (widths = ....) ideas on how code running under pycharm - works alright in interactive python window. thx. to all, after g'g lot have found workaround seems work within pycharm. workaround because (even python newbie) expected python not need explicit typecasting, not when using datatypes imported lib such numpy. def make_thetas(xmin,xmax,n): xs = np.array(np.linspace(xmin,xmax,n)) widths = (xs[1:] - xs[:-1])/2.0 thetas = xs[:-1]+ widths return thetas using docstrings type-hinting such below did not work def make_thetas(xmin,xmax,n): "&q
