You should have told me that about 10 years ago... :D I wonder when the command was introduced ? I found it by going down the list of field properties / commands looking for other issues like the Borderwidth error. There are several where the syntax example either does not work, throws an error or ...

Ooops - I managed to mix up the two screen shots sorry, I have just noticed this happens if border and margins are both set to zero (text is 11) : Screenshot 2023-08-02 at 16.48.45.png What logic is being employed and why? Also just found this command : function getTopOfFirstLine return item 2 of th...

Bernd, How do you do it? I've been trying to use the mouseloc to work out where the top of a row starts in an attempt to work out how the low values of border and width interact but at small text/border/margin sizes I'm struggling to position the mouse accurately. Your new code works on version 10 d...

Bernd,

I had not seen that problem. I notice that a error creeps in when the border size is less than 5 but its not a great issue, but I will try and work out what is going on.

Bernd, Genius, thank you! The calculation of the vertical position of the top line is far more complex than I imagined and would have taken me days if not weeks to edge towards which rather confirms Stam's point made above : use a datagrid ! For those who have not yet looked at Bernd's code correcti...

Ooops please ignore the screenshot above.

Craig, The issue with my code is that I have had to manually discover that I need to add 5 pixels to the vertical location of my edit field: ######### KLUDGE ######### put 5 into tKludge ######### KLUDGE ######### //Calculate the top posn of the line put tTopOfLines + (tLineNo*tCellHt) + tKludge int...

I agree that a datagrid is the way to go when displaying large data sets but when only a short list is required then I am happy to play. For example it struck while I was in discussions with the dog that my code could be placed in a behavior button which could be used by multiple short lists all usi...

why not just use a data grid which already has all this functionality built in? or the polygrid.... I suppose the simple answer is because I want to find out how they work and may be employed but in detail its complicated. Trevore DeVore did an amazing job in creating the datagrid. However, because...

Recently I have had an interest in being able to edit the lines of a scrolling list field. This is not possible with the standard control and a number of methods have been proposed in the past and with a bit of digging may be found in these forum pages. I decided to build a "simple" custom control t...

Hi Bernd, I'll send you an email and or a private message with my email which is also unchanged. Unfortunately the garage conversion, which was going to be an exercise / photographic studio for ME has been occupied by my 102 year old mother in law for the past two years. Grrrr!! Getting back to live...

A central repository of add-ons is essential for any dev tool, critically so for any tool marketed as "low code", since that refers to being able to tap into a healthy ecosystem of prefab scripts you don't need to reinvent. I agree! Unfortunately we don't have such a central repository. Livecode Sh...

Ghosts in my machine then

I have just attempted to access Livecode Share https://livecodeshare.runrev.com/ Screenshot 2023-07-30 at 12.11.26.png I'm have a medium speed internet connection and Livecode Share crawls. Searches take for ever and fail to return the searched for item and clicking on the list headers seems to resu...
