java tiny scrollbars

Hi i have created this function for creating constraints

Code:

  
    void buildConstraints(GridBagConstraints gbc,int gx,int gy,int gw,int gh,int wx,int wy){
        gbc.gridx=gx;
        gbc.gridy=gy;
        gbc.gridwidth=gw;
        gbc.gridheight=gh;
        gbc.weightx=wx;
        gbc.weighty=wy;
    }

I have also added the following components...

Code:

 
      setLayout(gridbag);
        
        /*Set the Bold CheckBox */
        buildConstraints(constraints,0,0,1,1,10,10); //? Afou einai void pos epireazei tin constraints
        constraints.fill=GridBagConstraints.EAST;
        gridbag.setConstraints(BoldCheck,constraints);
        add(BoldCheck);
        
        /*Set the Colors */
        buildConstraints(constraints,1,0,1,1,10,10); 
        constraints.fill=GridBagConstraints.NONE;
        gridbag.setConstraints(Colors,constraints);
        Colors.add("Add the Colors");
        add(Colors);
        
        /*Set the Italic Checkbox */
        buildConstraints(constraints,2,0,1,1,10,10); 
        constraints.fill=GridBagConstraints.WEST;
        gridbag.setConstraints(ItalicCheck,constraints);
        add(ItalicCheck);
        
        /*Set the Text Area */
        buildConstraints(constraints,0,1,3,1,10,10); 
        constraints.fill=GridBagConstraints.WEST;
        gridbag.setConstraints(WriteText,constraints);
        add(WriteText);
        
        /*Set the Red Scroll Bar */
        buildConstraints(constraints,0,2,3,1,30,10); 
        constraints.fill=GridBagConstraints.NONE;
        gridbag.setConstraints(Red,constraints);
        add(Red);
        
        /*Set the Blue Scroll Bar */
        buildConstraints(constraints,0,3,6,1,30,10); 
        constraints.fill=GridBagConstraints.NONE;
        gridbag.setConstraints(Blue,constraints);
        add(Blue);
        
        /*Set the Green Scroll Bar */
        buildConstraints(constraints,0,4,3,1,30,10); 
        constraints.fill=GridBagConstraints.NONE;
        gridbag.setConstraints(Green,constraints);
        add(Green);
        
        /*Set the Font Choice */
        buildConstraints(constraints,0,5,1,1,30,10); 
        constraints.fill=GridBagConstraints.NONE;
        gridbag.setConstraints(Fonts,constraints);
        for (int i=0;i<FontNames.length;i++)
            Fonts.add(FontNames[i]);
        add(Fonts);       
        
        /*Set the Size Choice */
        buildConstraints(constraints,2,5,2,1,30,10); 
        constraints.fill=GridBagConstraints.NONE;
        gridbag.setConstraints(Size,constraints);
        for (int i=5;i<25;i++)
            Size.add(String.valueOf(i));
        add(Size);

I try to find out why my 3 scrollbars appear in so small size
Have a nice day

IMHO, java's gui stuff is really difficult to program with, (especially when
you need stuff in an exact position in the windo).

but you might try increasing the gridwidth of the scroll bar (the 4th arg
of your function) although this could make things look strange.

you can also try the setPrefferedSize() method for the scroll bar objects.

i have found that this method usually works.

the thing is, those grid bag properties effect how the element is distributed
relative to the grid, but i don't think they effect the pixel size of the element itself.

Thx...really thx for yor reply.... Fortunately i can't increase the size of my scrollbar...

I can't find the SetPreferredSize....for my Scrollbars

Can you post the whole code? We can't tell what kinds of components these are.
Edit: Also, increasing the number of cells gives more control over how big things are (make bigger stuff span multiple cells)
