On Ubuntu it doesn't seem that the mouse wheel is normally expected to 
scroll through items in an option menu list.  Am I misunderstanding what 
you're doing?




Maybe I'm misunderstanding what you just posted, but I don't have any 
problems using the mouse wheel to scroll option lists except per the 
recipe I posted.


Try:
create a new stack
add an option menu
using the PI add more lines to the menu
go to browse mode and scroll with the mouse wheel

GoLiveNet problem

[Mark Wieder via use-livecode]

In my role today as troublemaker:

Open the GoLiveNet plugin
Select the Community icon
Click on the list of available "This Week in LiveCode" updates
Try using the mouse wheel to scroll the list

The up/down arrow keys work correctly.

Re: Datagrid Table - Allow editing a field only when an other field contains data

[zryip theSlug via use-livecode]

Matthias,

A possible solution is to add an EditFieldText handler inside the datagrid
group script.

*command* EditFieldText pTheFieldEditor, pTheIndex, pTheCol
*end* EditFieldText

This message is invoked by the datagrid table prior to create the field
editor allowing to edit the cell.
Three parameters are passed :
- the field editor reference: pTheFieldEditor
- the index of the row: pTheIndex
- the key (the column name): pTheCol

The trick consist to test the name of the column the user is trying to edit
(for example col3 of the datagrid) :

*if* (pTheCol is "Col3") *then*


and then  get the content of the cell of another column by using the
GetDataOfIndex
function:

*put* GetDataOfIndex(pTheIndex, "Col2") into tTheValueToTest


If you want to allow the edition of the cell, then give a chance to the
EditFieldText  to reach the datagrid library

pass EditFieldText

if not, then simply not send it

And don't forget to pass the command for others columns of the datagrid.


Here is a final handler applying the recipe for a "col3" based of the
content of "col2". If the cell contains "yes" in col2 then the user is
allowed to edit the content of the cell in col3, if not the cell remains
locked. You can change "yes" for any value or change the test for checking
if the cel in "col2"l is empty or not


*command* EditFieldText pTheFieldEditor, pTheIndex, pTheCol
  *if* (pTheCol is "Col3")
*then** put* GetDataOfIndex(pTheIndex, "Col2") into tTheValueToTest
 *if* (tTheValueToTest is "yes")
*then**pass* EditFieldText
 *end*
*if*
*  else**   pass* EditFieldText
  *end*
*if**end* EditFieldText
