Thanks Thorsten.

I'm just in the beginning stages of coding a game that needs to maintain
a grid for player and game stats... this well laid-out List gadget will be a
welcome addition.

PS -No problems with Demo using Win 10 Pro (x64) and PB 5.70 (x86)

Added: Resize Handle with autoresize defined column (minWidth/maxWidth)

Very useful, many thanks for sharing!
Obviously, this was a lot of work.

One important information is missing in the first post here:

Source code wrote:All OS

Much appreciated.

Added: Link with pop-up menu possible

Really nice Work.

But Can't use it, cause of DPI.

(It's the Problem of ALL Canvas-Based Gadgets)

I don't see that at all. Fonts are automatically scaled so it is just a case of using the current DPI scale factor alongside the available text metric functions to lay out the content appropriately. Aside from a lack of support for per-monitor DPI awareness, there are no real issues with the canvas gadget aside from having to put in a little more effort as PB cannot possibly scale all the content automatically. I have a substantial cross-platform grid control in development and it is behaving itself fine with regards DPI, although PB support for DPI awareness is somewhat limited right now.

@Thorsten : there seems to be massive flicker when dragging a horizontal scrollbar after I resize things to make the scrollbars visible. The client area seems to 'jump' about a bit. If you are editing a cell and move the vertical scrollbar, the string gadget can get left behind. Also, the various child controls occasionally overlay the scrollbars. All 'classic' problems when embedding child controls in a grid control - I should know as I had to contend with all of these problems with my original EsGRID control!

Win 7x64, PB 5.70.

Really usefull gadget missing in PB

Thanks a lot for sharing

Do you think it's possible to use it a day, like VirtualListIcon for load very quickly thousand of lines ?
viewtopic.php?p=513256#p513256
The first problem surely is lost the "all OS" side

Code: Select all

IncludeFile "ListExModule.pbi"

#Window  = 0

Enumeration 1
 #List
EndEnumeration

If OpenWindow(#Window, 0, 0, 500, 250, "Window", #PB_Window_SystemMenu|#PB_Window_ScreenCentered)
 
 HeureDebut = ElapsedMilliseconds() 
 ListEx::Gadget(#List, 10, 10, 400, 230, "", 25, "", ListEx::#GridLines|ListEx::#NumberedColumn) ; ListEx::#NoRowHeader|ListEx::#NumberedColumn|ListEx::#CheckBoxes
 
 ListEx::AddColumn(#List, ListEx::#LastItem, "Lines",    275)
 ListEx::SetHeaderAttribute(#List, ListEx::#Align, ListEx::#Center)
 
 For i = 1 To 1000
  ListEx::AddItem(#List, ListEx::#LastItem, #LF$ + "Line number " + Trim(Str(i)))
 Next 
 
 ListEx::SetRowsHeight(#List, 22)
 TempPasser$ = StrF((ElapsedMilliseconds() - HeureDebut) / 1000) + " secondes"
 MessageRequester("Time elapsed",  TempPasser$)
  
 Repeat
  Event = WaitWindowEvent()
 Until Event = #PB_Event_CloseWindow
  
EndIf

The reason for developing the module was that I needed a cross-platform solution.

I don't say it is a bug of Canvas... It is a Problem of Canvas-Based Gadgets.

If I multiply the inner-width with 1.5 (I use a Surface with a 150% dpi scale), than the gadget looks right. Simple problem, simple solution.

nasty bug fixed
added support for 'Tab' & 'Shift-Tab' in editable fields

Posted: **Wed Mar 06, 2019 11:22 pm**

Very good work, and an impressive function-list... and cross-platform, thank you very much for sharing!

I still need to test it on MacOS... But on Win10 it works fine here, with one exception: there seems to a canvas drawing error, see the screenshot here: https://cdn1.imggmi.com/uploads/2019/3/ ... 7-full.jpg

Do you plan to make it working in Dialogs (with automatic resizing) too?
If not, it shouldn't be a big problem to use the List (canvas-gadget) as child of an (automatically) resizing container gadget, and react on the resize events...

Just tested your module: ThumpUp !!!

Then I took a look to avoid the json color files and found,
that in SetColor are some attributes missing.

HeaderFront.i
HeaderBack.i
HeaderGrid.i
ScrollBar.i

They are not inside. Please add these too.

Still problems with horizontal scrolling. Problems also with combo cells. I am finding that when I edit one and then select another cell, the combo contents often disappear. Cannot reproduce this 100% consistently, though the following seems to do it most often : select the first combo cell and change contents to 'female'. Select another cell. Now double click the first combo cell again, do not change its contents and then double click another cell. The contents of the combo cell seem to be wiped.
