Flexiable Row heights in datagrid

Post by lumpo » Sun Feb 13, 2011 8:16 am

I am populating a DG from a number of custom props that contains 2 columns and 7 rows of text.For each line the amount of text is variable and so sometimes is within the space of the form field and others just disappears as it hits the field's lower limit (ie too much text).

IS is possible to have the rows dynamically adjust to the content of the field in the form? I am not using a fixed line height anywhere.

TIA

Data Grid forms support variable height rows. Tables do not.

See this lesson for information on creating a variable row height data grid form.

Thanks Trevor - figured it out and all's well... Sort of.
The rows all resize dynamically as data comes in (from a custom prop triggered from an rTree control) but I've lost the ability for a row to be highlighted. Clicking on the row allows me to extract data from the row ok. Have used DGH, intuition, human sacrifice, threats, promises and tears, but can't get the hilite ... Any suggestions?
Thanks

The data grid will change the color of a graphic named "Background" in your row template (see notes in setProp dgHilite). Have you included a graphic with that name? Is it visible and opaque?

Plus, do you have a mouseDown handler in the datagrid group script?

If yes don't forget to pass the dgMouseDown message to the datagrid engine:

Code: Select all

on mouseDown pWhichButton
   doMyStuff
   dgMouseDown pWhichButton
end mouseDown
