Hi,

I have the following code:

[code]
package research;

import java.awt.Font;
import java.awt.geom.Rectangle2D;

import javax.swing.JApplet;
import javax.swing.JOptionPane;
import javax.swing.JScrollPane;
import javax.swing.JTextArea;

import app.Util.Utility;
import app.Util.SAXTConstants.LocalizationConstants;

import com.mindfusion.jdiagram.Align;
import com.mindfusion.jdiagram.ArrowStyle;
import com.mindfusion.jdiagram.Box;
import com.mindfusion.jdiagram.FitSize;
import com.mindfusion.jdiagram.FlowChart;
import com.mindfusion.jdiagram.GraphicsUnit;
import com.mindfusion.jdiagram.RerouteArrows;
import com.mindfusion.jdiagram.TextFormat;

public class Goop extends JApplet {
private static final long serialVersionUID = 1L;

@Override
public void init() {
super.init();

flowChart = new FlowChart();

resizeTest();
}

private void initialize() {
flowChart.setSelectionOnTop(false);

flowChart.setArrowStyle(ArrowStyle.Cascading);
flowChart.setRouteArrows(true);
flowChart.getRoutingOptions().setTriggerRerouting(
RerouteArrows.WhileCreating | RerouteArrows.WhenModified);

flowChart.setMeasureUnit(GraphicsUnit.Pixel);

TextFormat textFormat = new TextFormat(Align.Center, Align.Near);
textFormat.setWrapAtCharacter(true);
flowChart.setTextFormat(textFormat);
}

private void resizeTest() {
flowChart = new FlowChart();
initialize();

JScrollPane pane = new JScrollPane(flowChart);
this.getContentPane().add(pane);
flowChart.setDocBounds(new Rectangle2D.Float(0, 0, 64000, 64000));

Box four = new Box(flowChart);
four.setFont(new Font("Arial", 10, 10));

JTextArea area = new JTextArea(5, 10);
JScrollPane pane2 = new JScrollPane(area);

int result =
JOptionPane
.showOptionDialog(
Utility.getApplet(this),
new Object[] { "Title", pane2 },
Utility
.getLocalizedString(LocalizationConstants.INPUT),
JOptionPane.OK_CANCEL_OPTION,
JOptionPane.QUESTION_MESSAGE, null, null, null);
if (result == JOptionPane.OK_OPTION) {
String symbolName = area.getText();
four.setText(symbolName);
}
four.setBounds(150, 150, 100, 100);

sizeUp(four, flowChart);
flowChart.add(four);
}

private FlowChart flowChart;

public void sizeUp(Box box, FlowChart canvas) {
Box sizerUp = new Box(canvas);

sizerUp.setText(box.getText());

sizerUp.setFont(box.getFont());

Rectangle2D.Float stringSize =
canvas.measureString(sizerUp.getText(), sizerUp.getFont());

stringSize.width = stringSize.width;
stringSize.height = stringSize.height + 1;

sizerUp.setBrush(box.getBrush());
sizerUp.setPen(box.getPen());
sizerUp.setBounds(stringSize.getBounds());

sizerUp.resizeToFitText(FitSize.KeepWidth);
sizerUp.resizeToFitText(FitSize.KeepHeight);

Rectangle2D.Float newBounds = sizerUp.getBounds();

box.resize(newBounds.width, newBounds.height);
}

}

[/code]

I have a method written called sizeUp that resizes the box to fit the text it is given.
When the applet starts, if I pass this string:
[code]
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
aaaaaaaaaaaaaaaaaaaaaaaaaaaa
aaaaaaaaaa
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
[/code]

it works alright.

If I pass a very long string (>1000 characters) as this:
[code]
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
[/code]
the resizeToFitText doesn't seem to work fine.

Should my logic there change, or does resizeToFitText have problem with large text?

Thanks,
Praveen

Hi Stoyan,

I call resizeToFitText first with KeepWidth and the with KeepHeight, as you can see from the sample code that I have pasted.

When I pass the small multiline text, both the resizeToFitText calls return true.

When I pass the two line text with > 1000 chars, both the calls are returning false.

So, the function cannot handle large text?

Thanks,
Praveen

Hi,

I have tried what you suggested. I added the following code before calling the resize methods.

[code]
stringSize.width = stringSize.width + box.getPen().getWidth() + 10;
stringSize.height = stringSize.height + box.getPen().getWidth() + 10;
[/code]

The problem still exists though. The functions still return false. Is there something else I must be doing?

Thanks,
Praveen

Hi,

I haven't set any explicit shape. So, I assume it is rectangle.

In the above example (with the Goop class), I have given the entire code so that you can see it. I only introduced some uncompilable code in "JOptionPane
.showOptionDialog(...".
Maybe you can change that and see for yourself this thing in action.

Thanks,
Praveen
