Table data font, and making table header disappear

[Stefan Volbers]

Hi there,

for a recent project I need to display lab data in huge letters. My
first version used few hundreds of labels in a grid to arrange all well,
but the performance in IE (once again) is too sluggish to satisfy my
customer.
Now I used table, and performance is great, but I can't make it display
the way I need it (did use table often before, but rather in a trivial way).

My problem is that I can't set the table data to render with a big font;
if I set one (applied to table.Table with setFont), it is only displayed
in the header.
Guess I somehow have to use table.pane.Pane's setFont(), but if so, how
to address the pane?

Furthermore I'd even prefer to not display the table headers at all, but
table.Table's headerCellHeight property ignores a height of 0 (quote
from the apidoc: "Allowed values: any Integer"). Sadly no thorough table
documentation seems to exist on the qooxdoo site (regarding 0.8 there is
even less docu than to 0.7 and 0.6...).

I'd appreciate if anyone could help me with my newbie-ish table problems.

TIA
Greetings,
Stefan

Hello Stefan,


it is possible to change the size of the font inside the table cells, but it
is a bit complicated.

You have to write an own cell renderer and overwrite the constructor of
qx.ui.table.cellrenderer.Abstract. Just copy the constructor code and add a
font-size entry to the map inside the compile() call.

      var stylesheet =
        ".qooxdoo-table-cell {" +
        qx.bom.element.Style.compile(
        {
          position : "absolute",
          top: "0px",
          overflow: "hidden",
          whiteSpace : "nowrap",
          borderRight : "1px solid " + colorMgr.resolve("table-row-line"),
          padding : "0px 6px",
          cursor : "default",
          fontSize : "20pt", // <-------------- here ;-)
          textOverflow : "ellipsis",
          userSelect : "none"
        })

Than you will have to modify the rowHeight property of the Table widget.

I am not sure if it is possible to hide the header of a table. Perhaps some
else know if and how this is possible?

Kind regards
Jonathan

Hi Jonathan, Christian,

thanks so far for your help!
Maybe heading for treevirtual is indeed a better idea, I will look into
that.

Greetings,
Stefan

The concept that wasn't mentioned is that treevirtual is a subclass of table. You can do exactly that same "appear" event on a table.
