Re: Where are the newbies?

I think I can even "feel" the aftermath of the new price policy: The german LC forum is almost dead and in this forum I see far less postings than I used to see. And even on the LC mailinglist it is very, very silent compared to the past. Too sad... :cry: This should be a read as a warning that act...

Re: Where are the newbies?

A pro developer wanting all the features would have to shell out £2K/year for the privilege - so where is the incentive? I have never been sure if there is a silent majority of Livecode users who do not use the forum or the list. Also are the success stories on the website the tip of the iceberg or...

Re: Where are the newbies?

I wonder why RunRev / Livecode went open source in the first place? From memory they started from a payment structure that did not work for them, tried the open source idea for a number of years and then decided it was not working and have ended up today with a similar fee structure to the one that ...

Re: How does a datagrid achieve almost unlimited rows?

Well that was interesting : the installer fails under LC version 9 but worked under version 10.

Happy to report that Stam's demo stack now works albeit with some errors when it does not like my image files.

Re: How does a datagrid achieve almost unlimited rows?

PS: I got these as part of the summer mega bundle, so for me these appear in my account under Thirdparty > LiveCode Enhancements (yours may be different if you purchased individual externals instead). The latest version of LiveCode enhancements was published in August, version 1.0.32... Thanks, I'v...

Re: How does a datagrid achieve almost unlimited rows?

FYI: Here is a comparison of Datagrid <-> PolyGrid in a LC blog https://livecode.com/datagrid-vs-polygrid-head-to-head/ Thanks for the link, its amazing how a non-programmer can build that list, I doubt I can do it. As Stam writes all these new plugins/externals suffer with an unforgivable lack of ...

Re: How does a datagrid achieve almost unlimited rows?

Something odd happening here. In version 10 DP 4 the stack loads with no errors but it does nothing.

Trying with version 9.6.8 throws this error :

I take it that it is a path issue given I have no drive D:

Re: How does a datagrid achieve almost unlimited rows?

Unfortunately your last demo stack does not display any images in the polylist. The data is being set but there are no items set. Given I have never looked at the polylist before I'm failing to get it to work.

Re: How does a datagrid achieve almost unlimited rows?

I wonder if either of you would use a data/polygrid to display a true grid of image thumbnails in the way of most image cataloging programs. I can imagine its quite possible to populate a datagrid form with multiple thumbnails per row but imagine that drag drop reordering would be difficult.

Re: How does a datagrid achieve almost unlimited rows?

Just tried the polygrid. Very simple to set up and similar scroll performance to a datagrid. Both the datagrid and the polygrid benefit from being supplied with smaller thumbnail images. Surprise surprise feeding both of them both with thumbnails improves the scrolling removing the stutter previousl...

I have found the polygrid widget to be easier to use than the datagrid
I have not tried using the polygrid but will have a go as it sounds interesting.

Re: How does a datagrid achieve almost unlimited rows?

But do you need it? Does the user need to see all those records at the same time? Is this an opportunity waiting to be discovered for simplifying record selection? The simple answer is no, this app does not need to display more than the 149 odd records it can presently display. The final output are...

Re: Datagrid form slow data load time

I think we are probably both correct in that rescaling a large image takes time and I'm guessing it occurs when needed i.e. when the scroll bar is moved.
I presume you read the property dgVScroll of the data grid?
Yes by intercepting the scrollbarDrag message
