Hi,

Each time interval maps to a separate cell (whose borders you wanted to hide earlier) and the 'Complete' suffix only means all lanes in that time interval. We'll have in mind adding complete-row custom drawing for next release. At this time you could draw text only in the middle cell of the row, e.g.

Code
Select All
if (e.getElement() == CustomDrawElements.ResourceViewCellComplete)
{
	if (bounds.getMinX() <= calendar.getWidth() / 2 &&
		calendar.getWidth() / 2 < bounds.getMaxX())
	{
		e.getGraphics().drawString(
			"test", (int)bounds.getMinX(), (int)bounds.getCenterY());
	}
}


Regards,
Slavcho

using reply#8 suggestion on saving the calendar to pdf. i took that example further to only select resource rows am interested in. however when saving those graphics, i come accross an error that doesnt seem to make sense. the names of certain items in the row arent displayed. can you assist me on this? Here is the code i use to chose rows and save them

Code (Java)
Select All
try {

			Paper paper = new Paper();
			paper.setSize(8.5*72, 11*72);
			paper.setImageableArea(
					0,
					0,
					8.5*72,
					11*72);
			PageFormat format = new PageFormat();
			format.setOrientation(PageFormat.LANDSCAPE);
			format.setPaper(paper);

			double x1= calendar.getElementBounds(CalendarElement.ResourceViewHeader,2).getBounds().getMinX();
			double y1= calendar.getElementBounds(CalendarElement.ResourceViewHeader,2).getBounds().getMinY();
			double y2= calendar.getElementBounds(CalendarElement.ResourceViewCell,2).getBounds().getHeight();
			double x2= calendar.getBounds().getBounds().getWidth();

			Rectangle2D r2 = new Rectangle2D.Double(x1,y1,x2,y2);

			RenderingHints rh = new RenderingHints(
					RenderingHints.KEY_ANTIALIASING,
					RenderingHints.VALUE_ANTIALIAS_ON);
			PdfGraphics2D graphics = new PdfGraphics2D(
					r2, GraphicsUnit.Point);

			graphics.setMarginBottom(5);
			graphics.setMarginTop(5);
			graphics.setMarginLeft(5);
			graphics.setMarginRight(5);
			graphics.setRenderingHints(rh);
			graphics.rearrange(
					GraphicsUnit.Point, r2);

			Globals.defaultCharset = "UTF8";
			graphics.createPage();
			graphics.setClip(r2.getBounds());


			calendar.print(graphics,format,0);
			graphics.save("SavedPDF.pdf");
			graphics.dispose();

		}catch (IOException e) {
			e.printStackTrace();
		}

That looks like all items with X coordinate greater than a certain position. It could be the control calculates text layout with some delay or applies internal text clipping. Are these items off-screen at the time of export? Alternatively try setting a larger clip width or removing the clip path (in case our PdfGraphics implementation applies it to text but not rectangles).

Yes, when i use
Code (Java)
Select All
calendar.printPreview(format);

the items in the end are offscreen, which might be the cause of this. I still dont understand, if they are offscreen, how am i able to still print the items but not their headerText.

EDIT: so calendar prints its content on PdfGraphics but leaves out the text?
Code (Java)
Select All
calendar.print(graphics,format,0);

It looks like you are passing smaller rectangle to print (via Paper instance's size) than to PdfGraphics pages (via rearrange). So in that case the pagination code might be skipping drawString calls outside of Paper size completely, while relying on clipping for the rectangles, but PdfGraphics not performing clipping as expected due to its larger size.

Our test code above is passing same sizes to both Paper and PdfGraphics, from calendar.getBounds result. Maybe in your case try passing the r2 size to both.

After further investigation, it does work. what i do suspect is the format change from landscape to portrait size isnt applied to the item text.
