I have a unique requirement where I need to display all the contents of an attribute in a sub-grid. This attribute stores multiple line of text i.e. a few paragraphs of text. The maximum column length of 300px is not enough to display such text without cutting off.
Is there a way I can increase the row height in sub-grids so that long text warps into multiple lines?
No I don't believe this is possible. The row height is fixed.

Currently, each column has a pixel width. So there are 2 issues I'd like ot tackle here: 1.) If there are only a few columns, I’d like columns to fill the entire table so there is not empty space. So for example, if there are 3 columns, each of those columns will be 33.33% wide. 2.) We'd like to remove avoid horizontal scrolling by either having the column widths fit to the content or also allowing cell content to wrap if we need to. Bonus: If there's a way to say, "Hey if there are an extremely high number of columns (like 70 columns for example), then use a horizontal scroll" that'd be awesome! Thanks for any help!!
Instead of this:
pixelWidth
Like this:
percentageWidth

I am creating one pdf file showing a list of all employees and their salaries. At the end of the page it is showing the total of all salaries.
I am using a for loop to add multiple rows to table.
The problem is:
at the end the row, the total salary doesn't fit on the same page and it is shown on the next page.
So is there any way that I can calculate the height of the page and then fix the height of each cell? And then accordingly, limit the number of rows.
So that at the end of the page, I can show the total number of rows and further record from next page.
Calculate the height of the page: well... you decide on the size of the page when you create a Document object. You can choose any size you want.
Calculate the height of a PdfPTable: that's explained in chapter 4 of my book. When you create a PdfPTable, you add PdfPCell objects to an object that only exists in memory and that doesn't know anything about page size. By default, the width is expressed as a percentage of the available width of the page to which you'll add the PdfPTable. Only when you add the PdfPTable to a specific Document, the exact width and the height will be calculated (which is too late for you).
If you want to know the height in advance, you need to define an absolute width (not a percentage). Tables with the same content and a different width will have a different height. Defining an absolute width is done like this:
table.setTotalWidth(width);
table.setLockedWidth(true);
In this snippet (taken from the TableHeight example), width equals the width of the page minus the left and right margin. You're defining the width of the page and the margins upon creation of the Document object. By default, the page size is A4, so the default width is 595 user units and the default margins are 36 user units.
So, one way to solve your problem, would be to add rows in a loop and calculate the height of each row with the getRowHeight() method or the height of the complete table with the getTotalHeight() method (both methods will return 0 if you omit setting the total height). If you see there's not enough space to add the summary row, you can use the deleteLastRow() method to remove that last row and to create it anew in a new table on the next page.
That's one solution. Another solution could be to use table and cell events, but that's more difficult to explain.
I have several textfields on a single row in the same band. The first of them is having a larger font than the rest. However, the size of this font might change for each record. How can I set the height of the other textfields to be dependant of the height of the first one?
Thanks for your help,

On each field in the row set Stretch Type to be Relative to Tallest Object.
I use iReport to create reports, and I would like to know if there is a way to set the width of "optically grouped fields". They should be set to the minimal size that still displays longest text. I have Static Text on left side and Text Field right of them. This Text Fields are set to the width 150 and alignment to right, but I'd like to set smaller size to wipe out white spaces.
Consider some thing like this
Name: Paul
Surname: Smither
And want automatically to
Name: Paul
Surname: Smither
etc. can be smaller then preset size but no bigger.
Is there a way?? even some component
You cannot change the element width dynamically without using Java frameworks.
The quote from JasperReports Ultimate Guide:
ELEMENT SIZE
The width and height attributes are mandatory and represent the size
of the report element measured in pixels. Other element stretching
settings may instruct the reporting engine to ignore the specified
element height. Even in this case, the attributes remain mandatory
since even when the height is calculated dynamically, the element will
not be smaller than the originally specified height.
You can read this article for better understanding the mechanism of changing the element size.
If it's genuinely just a couple of fields that come from the same row in the dataset, then you could hack something together.
Use a monospace font
Define your maximum field length with a String set to N spaces. For example:
$P{MaxLengthString} default value is 10 spaces: " "
Change your field text from $F{FirstName} to this:
$P{MaxLengthString}.substring(
$P{MaxLengthString}.length() + $F{FirstName}.length() - java.lang.Math.max($F{FirstName}.length(), $F{LastName}.length())
) + $F{FirstName}
That is... er... a bit more complex. And it only works with monospace fonts. And I can't believe I really suggested this. Don't do it. (But it ought to work.)
I want to have a tableview create rows that look like this:
value1 item1 container1
value10 item10 container10
value100 item100 container100
value2 item2 container2
What I am trying to show is that the first word (value) will have a set length of 12 and then the second word (item) will have a set length of 10 and then the last word (container) is just tagged on at the end.
I am pulling these from a SQLite database and don't want to use multiple lines, but read in a strictly formatted structure like this.
You can layout a custom UITableViewCell in Interface Builder, where you drag two UILabel views onto the Content View and set their size appropriately (Notice that the letters may vary in width, so even though you know it's 10 chars in length, you don't know the maximum width, please keep that in mind)
Then you just fill the open space at the right of a cell with another UILabel, layout it to cover the open space and set it to autoresize it's width and set the right margin to be fixed.
There are quite a few tutorials available on how to use the custom cell in your tableView, I can recommend you this screencast. It explains how you can initialize the custom cell and how you can access the custom labels.
It sounds like you want something like an old-fashion text display in which then nth character in row zero always lines up the nth character in every row.
Even using carefully positioned labels in a custom tableviewcell, you will have to strictly control the specific font and its size if you want all the characters to line up in fixed width column. You will need a fixed width font to begin with and you will have to set the size precisely.
You might want to consider whether this is necessary. iPhone users are used to propionate width text displays. Very precise columns of text might make it difficult to discern rows. I would test first with just a simple table before spending the time tweaking the columns.
