Hello,
I am trying to create an extension in which you can highlight single or multiple lines of text in the request or response tabs. I am having an issue when you add a “Graphic” to the IMessageEditor text area that it disappears when it is either selected or you highlight a new line of text.
Highlight Method:
/*
* Graphics g: Takes components graphics object.
* IMessageEditor req: Request Text Area
* IMessageEditor res: Response Text Area
* String text: Selected line to highlight
* Int x,y,width,height: Dimensions
*/
public Graphics highlight(Graphics g, IMessageEditor req, IMessageEditor res, String text, int x, int y, int width, int height) {
Graphics2D gr = (Graphics2D) g;
FontRenderContext context = gr.getFontRenderContext();
Font font = gr.getFont();
int textWidth = (int) font.getStringBounds(text, context).getWidth();
LineMetrics ln = font.getLineMetrics(text, context);
int textHeight = (int)(ln.getAscent() + ln.getDescent());
int x1 = x + (width - textWidth)/2;
int y1 = (int)(y + (height + textHeight)/2 - ln.getDescent());
gr.setComposite(alphaComp);
gr.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
gr.setColor(Color.YELLOW);
gr.setBackground(Color.YELLOW);
gr.fillRect(x, y, width, height);
return g;
}
I am accessing the text area component with the following methods:
IMessageEditor requestViewer = messageEditor.getRequestViewer();
JTabbedPane requestViewerPane = (JTabbedPane) requestViewer.getComponent(); //Request Tab
JPanel jCompPanel = (JPanel) requestViewerPane.getComponent(0); //Get Request’s Raw Tab
JComponent jComp2 = (JComponent) jCompPanel.getComponent(1); //Get Layout
JComponent txtArea = (JComponent) jComp2.getComponent(0); //Request text area
Highlight Call:
highlightUtils.highlight(txtArea.getGraphics(), requestViewer, responseViewer, "Cookie: 12345", e.getX(), e.getY(), strw, strh);
How would I got about fixing this issue and is there a better way to implement this type of highlighting?
