Something about lines being 1 pixel shorter?

2004-03-16 02:39

I remember something being said about lines being drawn shorter than other elements in the group; which resulted in the disjointed border in the stretch sample. Am I right?

 

Has anyone gotten a workaround? As mentioned in another thread, I need a border around the entire table body, so I can't just use a rectangle. I created 2 vertical lines in the detail band grouped with the text field. The table headers have their own borders. The column footer band has a horizontal line.

 

The problem is that the bottom line is not joined to the lines that represent the sides of the table.

set the y value = -1, this should fix the problem

Actually... it didn't. Maybe that would've worked in the xml file but I don't use the xml file. Doing line.setHeight(-1) for the lines at the side of each field (all 3 in a group) somehow managed to cause the field to disappear entirely, leaving only the lines (still separated).

Hi,

 

These gaps occur only when the line is thin

(pen="Thin").

This is because in this case the line is half a pixel

thick and half a pixel shorter at both ends, leaving

us with a on pixel gap between two lines.

 

If you put the line at y=-1, make sure you also add

one pixel to its height. This way the lines will overlap

one pixel giving you continuity.

However, this trick is bad news for HTML and XLS

formats where overlapping elemets are ignored.

This is probably what happend with you text elements

if placing the line at -1 would actualy make it

overlap with some text fields in the above band.

I have to see you design to make other suggestions.

 

I hope this helps.

Teodor

I don't have an xml design. And basically, I don't have a height. And since I need probably need to do XLS and HTML in the future, overlap probably isn't an option.

 

Right now, I'm actually creating line elements of 0 height and setting the stretch to relative tallest object attribute. I create 2 such line elements and put them in the same group as the textfield, counting on the textfield to stretch itself and stretch the 2 lines together. Any workaround so far?

 

I'll have to put in offset x and y later, so that may help alleviate this problem when I put in all the calculations for offset of the borders. It just doesn't look very nice right now...
