Benedikt Schlagberger updated NETBEANS-3355:
--------------------------------------------
Description:
When painting in the sidebar using the {{SideBarFactory}}, the painted Graphic
is offset for large files. To reproduce, create a NetBeans plugin project and
add the following class:
{code:java}
package com.mycompany.sidebar_test;
import java.awt.Color;
import java.awt.Dimension;
import java.awt.Graphics;
import javax.swing.JComponent;
import javax.swing.text.JTextComponent;
import org.netbeans.spi.editor.SideBarFactory;
public class MySidebarFactory implements SideBarFactory {
@Override
public JComponent createSideBar(JTextComponent jtc) {
return new MySidebar();
}
private class MySidebar extends JComponent {
@Override
protected void paintComponent(Graphics g) {
g.setColor(Color.BLUE);
g.fillRect(0, 0, 10, 1000); // Paint blue rectangle starting at the
top of the sidebar with height of 1000px
}
@Override
public Dimension getPreferredSize() {
Dimension dimension = new Dimension(this.getParent().getSize());
dimension.width = 10;
return dimension;
}
}
}
{code}
Register the {{SideBarFactory}} using the following {{layers.xml}}:
{code:xml}
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE filesystem PUBLIC "-//NetBeans//DTD Filesystem 1.2//EN"
"http://www.netbeans.org/dtds/filesystem-1_2.dtd";>
<filesystem>
<folder name="Editors">
<folder name="SideBar">
<file name="com-mycompany-sidebar_test-MySidebarFactory.instance">
<attr name="location" stringvalue="West"/>
</file>
</folder>
</folder>
</filesystem>
{code}
Now start the plugin and open a project containing a large file for example the
[StrBuilder.java|https://raw.githubusercontent.com/apache/commons-lang/master/src/main/java/org/apache/commons/lang3/text/StrBuilder.java]
from the apache commons lib.
The painting is offset by a large amount as you can see in the attached
screenshot (blue rectangle should start in line 1, not 2150). When shortening
the file and re-opening it, the marker moves, so I suppose this is related to
the file size.
