Rowheight of a Crosstab

rbuser

I've seen this comments in a old message of 2001 from Nard


1. Check out crosstab example 127 (ct0127.pas) located in
RBuilder\Demos\Crosstab\Demo.dpr.
It show ane example of controlling the captions.

Using the Crosstab events you can control much of the formatting and
display. However you can specifiy a width/height for columns.


Ok, chaning captions works fine and i'm using it for quite a while, but
chaning the height of a 'band' (1 detail row) is still unknown to me, what
property has to be changed for this or, how could we do this.

Kind Regards

Hi Harry,

Sorry, the crosstab component measures the row height and width based on the
font size of the largest caption. There is no way to alter this size other
than creating a new crosstab renderer.

Will the crosstab recalculate if you decrease the size of the font of the
field, because, if so, honestly, you are taking to much blank spaces between
2 rows !!
I've changed all font to Arial8 point and still only 20 rows get on a
landscape paper, in a regular report i'm getting over 34 !!!

I researched this by looking at the source code. There is a margin of 1588
microns being added to the cell on each side. I calculated this in inches to
be 0.0625 of an inch. The margin is defined as a constant, see ppCTMain,
there is margin declared at the top: ciTextMargin.

Nard,

Honestly, i don't like to go in discussions with you guys because i really
admire the ReportBuilder-guys. Its a great product.

But, i will attach a very small example that proves that it is not 0,0625
inch or 0,15cm, even the bottom margin between the last line and the top op
the next this should be 3mm, in reality it goes up to 6mm.

Not a huge problem as we can 'change' this behaviour.
Is it correct that i must open the package rbCT76 adn recompile it. Put the
resulst back into RBuilder\Lib ???

I did not write that code so I could be wrong. Since it is a margin, it is
added twice.

In ppCtRend there is code like this, where the CaptionWidth is calculated as
the TextWidth and then the margin is added on.


liCaptionWidth := liCaptionWidth + (ciTextMargin * 2);
