[PB Cocoa] Methods, Tips & Tricks

[mrbungle]

Acknowledged. However, this code works fine on Big Sur and Monterey running on an Intel Mac using PB 6 or compiled apps on the Mac M1. I believe the issue is with the C backend of PB 6 using the native ARM version. Even functions like like NS.Size don't seem to work.

[mk-soft]

Please move it to bug reports "Bugs - C backend"

I have modified my source code to sort ListIconGadget contents by clicking on the column header cell and displaying an ascending or descending icon to also work in PB 6.00 with Asm and C backend and in older PB versions (successfully tested on MacOS 11.7.2 'Big Sur' on an iMac 2019 with Intel x86-64):

I have modified my example to justify text in the columns of the ListIconGadget to work both in PB 5.73 and earlier and in PB 6.00 and newer. This has become necessary because Fred has changed internals of the cells in ListIconGadgets. In PB 6.0 Fred implemented the new PBIconTextCell which enables the display of both an icon and text in a single cell. But therefore unfortunately the old modifications don't work anymore.

This new example uses the old routines in PB 5.73 and earlier and a callback in PB 6.00 and newer. Furthermore the example was extended to change the justification of header cells (which didn't change in PB 6.00) separately from the column cells. The following example was successfully tested on these MacOS versions:

• 'Big Sur' 11.7.3 with PB 5.73 and PB 6.00 (Asm and C backend)
• 'Monterey' 12.6.3 with PB 5.73 and PB 6.00 (Asm and C backend)
• 'Ventura' 13.2 and 13.2.1 with PB 5.73 and PB 6.00 (Asm and C backend)

Hello Shardik,

thanks a lot for your example, and the hard work to make it work on PB 6.00

When I click the "Center", the columns are right-justified
And when i click "Right", the columns are centered

I guess it's just a "quiproquo"

[mk-soft]

The "CocoaMessage(0, GadgetID(ListIconID), "setDelegate:", AppDelegate)" destroy the Eventtype "PB_EventType_Change"

[Shardik]

When I click the "Center", the columns are right-justified
And when i click "Right", the columns are centered

Sorry, but I can't confirm your findings. I have just also tested my example on MacOS 13.2 and 13.2.1 'Ventura' and it works like a charm in PB 6.00 with Asm and C backend.

Did you try my exact example? If not you probably changed "Right" (#NSRightTextAlignment = 1) and "Center" (#NSCenterTextAlignment = 2) because my example uses the GadgetIDs subtracting 6 for the alignment (in the FrameGadget #5) and the OptionGadget for "Right" is #7 but at the right side and "Center" is #8 and in the middle.

[Mindphazer]

Well, that's weird. I copied your example without changing any character.
I did it again, and have the same behaviour. If i select "Center" radio buttons, the columns are right justified
And if i select "Right" radio buttons, the columns are centered.
I'm on a Macbook Pro M1, macOS 13.2.1

I changed your Select this way to make it work as expected :

Code: Select all

Select OptionGadgetID
        Case 2
          SetListIconColumnJustification(0, 1, 0, #True)
        Case 3
          SetListIconColumnJustification(0, 1, 2, #True)
        Case 4
          SetListIconColumnJustification(0, 1, 1, #True)
        Case 6
          SetListIconColumnJustification(0, 1, 0)
        Case 7
          SetListIconColumnJustification(0, 1, 2)
        Case 8
          SetListIconColumnJustification(0, 1, 1)
      EndSelect

Maybe it's a problem with your ARM processor and the C backend compilation. Unfortunately I am only able to test on my iMacs with Intel processor. But thank you for your workaround!

Hello,

I found 'Sorting data by clicking a column header ' but the code don't work correctly. The text in the cell disappear, It is certainly too old.,

I found a solution so I post my code. I use selectcolumn and I switch off he highlights. I switch on the highlights if it is a row selected.

Hello,

I found 'Sorting data by clicking a column header ' but the code don't work correctly. The text in the cell disappear, It is certainly too old.

You are right. My example Sorting data by clicking a column header was posted by me in April 2013 and doesn't work anymore with PB 6.0+. Beginning with PB 6.0 Fred implemented the new PBIconTextCell which enables the display of both an icon and text in a single cell. But therefore unfortunately the old modifications don't work anymore in PB 6.0+. Therefore I had already posted this update of my example which works in PB 5.73 and older and in PB 6.0+. My example has the advantage over your example to also display a sort indicator icon at the right side of the header cell in the sorted column. And it is possible to change between ascending and descending sort order by successive clicks on a header cell.

Is it possible to get this work under 14.x.x?

Recolor a button gadget using a Core Image Filter
