Hello everyone, I have a small problem, I have a main window with two scrollArea gadgets, at program startup they are filled with more gadgets(variable number of gadgets), so far so good, I created a procedure to increase the vertical scroll area, but it works only the next time, pressing refresh on the button I created on the interface, the procedure that is called both for the refresh button and at program startup after the panes are filled is as follows, surely I am doing some nonsense wrong:
Code: Select all
Procedure Mia_RidimensionaScroll(fake = 0)
Protected NumeroBloccati, NumeroSbloccati, DimensioneDestra, DimensioneSinistra
ForEach ListaGiochi()
If ListaGiochi()\Bloccato
NumeroBloccati + 1
Else
NumeroSbloccati + 1
EndIf
Next
If NumeroBloccati > 12
DimensioneDestra = 429 + (((NumeroBloccati - 12) + 2) / 3) * 90
SetGadgetAttribute(#ScrlArea_unLock, #PB_ScrollArea_InnerHeight, DimensioneDestra)
Else
SetGadgetAttribute(#ScrlArea_unLock, #PB_ScrollArea_InnerHeight, 429)
EndIf
If NumeroSbloccati > 12
DimensioneSinistra = 429 + (((NumeroSBloccati - 12) + 2) / 3) * 90
SetGadgetAttribute(#ScrlArea_Lock, #PB_ScrollArea_InnerHeight, DimensioneSinistra)
Else
SetGadgetAttribute(#ScrlArea_Lock, #PB_ScrollArea_InnerHeight, 429)
EndIf
EndProcedure

Hi TI-994A, thank you very much for the link to your code, I will look at it in depth these days, yes I am creating a launcher for steam game library, and I fill a ScrollAreaGadget with many gadgets, for each image it's total 4 gadgets(4 imagegadgets), because I need the events of all 4 elements, only drawback is that when it's so many images then the redraw operation becomes slow if I refresh the windows, so any help I get I'm very glad, and I try to take inspiration from your examples and solutions.

Hello again, @le_magn. You're right; too many gadgets can really put a toll on performance and footprint.
I believe that the
ImagePickerGadget() would suit your needs quite well. It's lightweight, cross-platform, and it works out of the box.
Just plug & play! 
BTW, I just posted an update to the module code. It now
supports more image types and contains some additional fixes.
I hope that you'll progress well with this gadget. But please feel free to reach out if you might require any specific tweaks.

Thank you very much TI-994A, I did some tests with your module and I must say I was impressed, I tested it with a folder of more than 400 images, the speed is impressive, I will probably use your module to rewrite later versions of my application, I'm going to take a look at the updated version of the module, in the meantime I thank you, you were really very kind
