@Thorsten1867,

I have found what appears to be a bug in version 20033101.
I have been able to reproduce the bug in the demo code you supply with the ListEx:

If you change the width of the column from 60 to 80 in line 10292 and then 'run' - two problems appear:

As expected a horizontal scroll-bar is drawn.
1. This scroll-bar partially hides row 10
2. Rows 9 and 10 no longer respond to left-clicks to highlight the clicked row or events.

Hi Thorsten

Thanks for all the updates. The gadget is almost perfect.

Any chance that you can get the gadget to automaticlly scroll if you are using the keyboard and you reach the bottom row of the screen? The standard gadget does this.

The cursor keys work for me?!?

Strange... Must have had an old version. Downloaded again and it works fine.

Thanks for the answer though.

Keep up the good work!

Hi Thorsten.
Thanks for the powerful gadget.

SetItemColor for the "test" column number 5 does not work, but it does if you select column number 6.

Hi Thorsten

Any chance of adding an minimum size to the scrollbar slider as i gets really small when showing a long list...

Fixed it!

Changed...

Code:

If ListEx()\ScrollBar\Item()\Thumb\Size < dpiY(6) : ListEx()\ScrollBar\Item()\Thumb\Size = dpiY(6) : EndIf

to

Code:

If ListEx()\ScrollBar\Item()\Thumb\Size < dpiY(20) : ListEx()\ScrollBar\Item()\Thumb\Size = dpiY(20) : EndIf

in the procedure CalcScrollBarThumb_

Regards

I'm trying to use the ListEx gadget in a splitter gadget. If I run this code, there seems to be a problem with the auto resize. Am I doing something wrong?

Code:

IncludeFile "ListEx\ListExModule.pbi"
IncludeFile "TreeEx\TreeExModule.pbi"

OpenWindow(0,0,0,1280,720,"Test",#PB_Window_ScreenCentered!#PB_Window_MaximizeGadget|#PB_Window_MinimizeGadget)
TreeEx::Gadget(1,0,0,0,0,"Tree",TreeEx::#AutoResize, 0)
ListEx::Gadget(2,0,0,0,0,"Test 1",1,"",ListEx::#GridLines|ListEx::#AutoResize, 0)
SplitterGadget(3,0,0,WindowWidth(0),WindowHeight(0)-MenuHeight(),1,2,#PB_Splitter_Vertical|#PB_Splitter_Separator)
SetGadgetAttribute(3,#PB_Splitter_FirstMinimumSize,250)  
SetGadgetState(3,250)
ListEx::SetAutoResizeFlags(2, ListEx::#Height|ListEx::#Width)
ListEx::SetColumnAttribute(2,0,ListEx::#ColumnWidth,600)
ListEx::AddColumn(2,1,"Test 2",260)
ListEx::AddColumn(2,2,"Test 3",82)
ListEx::SetHeaderAttribute(2, ListEx::#Align, ListEx::#Center,2)
ListEx::SetColumnAttribute(2, 2, ListEx::#Align, ListEx::#Center)

ListEx::DisableRedraw(2,#True)

For i=1  To 1000
  ListEx::AddItem(2,ListEx::#LastItem,"Column 1" + #LF$ + "Column 2" + #LF$ + "Column 3")
Next

ListEx::DisableRedraw(2,#False)

Repeat
  
  event=WaitWindowEvent()
        
Until event=#PB_Event_CloseWindow

Regards

Paul

Update:

Attribut '#ParentGadget' for resizing (e.g. ContainerGadget)
Attribut '#MinimumSize' for minimum size of scrollbar thumb

@mrv2k
Please try!

I think its a DPI issue. My display is normally set to 125% scaling. If I turn scaling to 100%, the header and column problems go away.

If I run this code at 100% scaling, the gadgets are perfect.

Code:

IncludeFile "ListEx\ListExModule.pbi"
IncludeFile "TreeEx\TreeExModule.pbi"

OpenWindow(0,0,0,1280,920,"Test",#PB_Window_ScreenCentered!#PB_Window_MaximizeGadget|#PB_Window_MinimizeGadget)
TreeEx::Gadget(1,0,0,0,0,"Tree",TreeEx::#AutoResize, 0)
ListEx::Gadget(2,0,0,0,0,"Test 1",1,"",ListEx::#GridLines|ListEx::#AutoResize, 0)
SplitterGadget(3,0,0,WindowWidth(0),WindowHeight(0)-MenuHeight()-200,1,2,#PB_Splitter_Vertical|#PB_Splitter_Separator)
SetGadgetAttribute(3,#PB_Splitter_FirstMinimumSize,250)
SetGadgetState(3,250)

ListEx::SetAutoResizeFlags(2, ListEx::#Height|ListEx::#Width)
ListEx::SetAttribute(2,ListEx::#ParentGadget, 3)
ListEx::SetAttribute(2,ListEx::#MinimumSize, 20)
ListEx::SetAutoResizeColumn(2,1)
ListEx::SetColumnAttribute(2,0,ListEx::#ColumnWidth,GadgetWidth(3)-257-342) ; 257 =250+7 For Splitter | 342 = 260+82 For Columns
ListEx::AddColumn(2,1,"Test 2",260)
ListEx::AddColumn(2,2,"Test 3",82)


ListEx::Gadget(4,0,WindowHeight(0)-205,WindowWidth(0),180,"Test 1",WindowWidth(0)-342,"",ListEx::#GridLines|ListEx::#AutoResize, 0)
ListEx::SetAutoResizeFlags(4, ListEx::#Height|ListEx::#Width)  
ListEx::SetAutoResizeColumn(4,1)
ListEx::SetAttribute(4,ListEx::#MinimumSize, 20)
ListEx::AddColumn(4,1,"Test 2",260)
ListEx::AddColumn(4,2,"Test 3",82)

ListEx::DisableRedraw(2,#True)
ListEx::DisableRedraw(4,#True)

For i=1  To 10000
  ListEx::AddItem(2,ListEx::#LastItem,"Column 1" + #LF$ + "Column 2" + #LF$ + "Column 3")
  ListEx::AddItem(4,ListEx::#LastItem,"Column 1" + #LF$ + "Column 2" + #LF$ + "Column 3")
Next

ListEx::DisableRedraw(2,#False)
ListEx::DisableRedraw(4,#False)

Repeat
  
  event=WaitWindowEvent()
        
Until event=#PB_Event_CloseWindow

If I set it to anything over 100%, the header bar becomes extended and the columns sizes break. It also breaks SetAutoResizeColumn.

I can probably get around the splittergadget problem by intercepting the resize event and doing a bit of math to calculate the first column width. The #ParentGadget is great, but splitter gadgets are dynamic and you would need to know the dimensions of which ever side the ListEx is in. This might be possible by getting the ListEx GadgetWidth() after the splitter is drawn as it automatically resizes each gadget.

#MinimumSize - Works Great!

Thanks for all you help!

Paul

P.S. Theres a typo on line 7491. It reads...

Code:

If ListEx()\ParentNum <> #PB_Default

It should be

Code:

If ListEx()\Parent\Num <> #PB_Default

Thanks Thorsten!

Works absolutely perfectly now!

Only had to comment out a debug.

Great Work!

Sorry Me Again!

Looks like something broke on the scroll bars with the new update. The scrollbar button scrolls at a different speed to the mouse. It does it on the example if you add a few more lines. I checked on different DPI's and it's not related.
