Is there a property to make the checkboxes on a checked listbox larger?

[Justin M]

Hi there folks! I am new to checked listboxes, and recently I made the text font larger on the listbox, but is there a property to make the checkboxes larger to go with it?

Thanks a lot!

hi there,

try from this link. It works for me on vb6

No, there is no such property. You will probably have to make your own custom listbox user control

Not sure if checkboxes get bigger with the font increase, but it may still be better than the intrinsic Listbox

HTH,

The answer to "making it bigger" (stop giggling) is not larger fonts, etc. but instead raising the DPI setting on the system (or monitor on current Windows versions supporting per-monitor DPI). High DPI poses its own challenges of course but rejecting that as an answer is just trying to buck the tide.

What you have is a situation where the monitor DPI has increased, but to make legacy coding techniques continue working (sort of) you are telling Windows to keep pretending the monitor has 96 pixels per inch. The result is that everything keeps on "getting smaller" every time you move to a denser monitor.

If you substitute a ListView for the ListBox (will look the same), you can make them bigger


See this project.

All I did for the proof of concept here, Module1 contains the function 'InitCheckHIML', I simply changed all the 16s to 32s for the ListView (the TreeView I think you'd have to make the font bigger first because they got squished when I tried).

Public Sub InitCheckHIML()
Dim hIco As Long
Dim lPos As Long

himlCheck = ImageList_Create(32, 32, ILC_COLOR32 Or ILC_ORIGINALSIZE, 1, 1)
ImageList_SetIconSize himlCheck, 32, 32
hIco = ResIconTohIcon("CHK_STD_UNCHKD", 32, 32)
Call ImageList_AddIcon(himlCheck, hIco)
Call DestroyIcon(hIco)
hIco = ResIconTohIcon("CHK_STD_CHKD", 32, 32)
Call ImageList_AddIcon(himlCheck, hIco)
Call DestroyIcon(hIco)
hIco = ResIconTohIcon("CHK_STD_DIS", 32, 32)
Call ImageList_AddIcon(himlCheck, hIco)
Call DestroyIcon(hIco)
hIco = ResIconTohIcon("CHK_EXT_PAR", 32, 32)
Call ImageList_AddIcon(himlCheck, hIco)
Call DestroyIcon(hIco)
hIco = ResIconTohIcon("CHK_EXT_EXP", 32, 32)
Call ImageList_AddIcon(himlCheck, hIco)
Call DestroyIcon(hIco)
hIco = ResIconTohIcon("CHK_EXT_DEF", 32, 32)
Call ImageList_AddIcon(himlCheck, hIco)
Call DestroyIcon(hIco)
hIco = ResIconTohIcon("CHK_EXT_X", 32, 32)
Call ImageList_AddIcon(himlCheck, hIco)
Call DestroyIcon(hIco)
hIco = ResIconTohIcon("CHK_CST_UNCHKD", 32, 32)
Call ImageList_AddIcon(himlCheck, hIco)
Call DestroyIcon(hIco)
hIco = ResIconTohIcon("CHK_CST_CHKD", 32, 32)
Call ImageList_AddIcon(himlCheck, hIco)
Call DestroyIcon(hIco)

The owner-drawn ListBox can do a custom appearance.

Ok so I tested it with the font size changed too, it worked out even better. For the finishing touch I also assigned 32x32 imagelist to the regular icons. To compare, the default sizes can be seen on the TreeView on the right, which wasn't touched.

This is with 18-point Tahoma:


Do note though if what you're doing is adjusting for a higher DPI, listen to dilettante, you shouldn't be doing that by changing the font points.

Hi

you could use a Flexgrid..

place on a Form.. 1xFlexgrid, 1xListbox, 1xCommandbutton

'set check or remove Check  Cell
Public Property Let FlexCellChecked(Flex As MSFlexGrid, Row As Long, _
                                    Col As Long, vData As Boolean)
   Dim SaveRow As Long, SaveCol As Long
      With Flex
         .Redraw = False
         'save Position
         SaveRow = .Row
         SaveCol = .Col
         .Row = Row
         .Col = .Col
         If vData Then
            'True
            .Text = "a"
         Else
            'False
            .Text = vbNullString
         End If
         'save again
         .Row = SaveRow
         .Col = SaveCol
         .Redraw = True
      End With
End Property

'True/False Cell Checked

                                    Col As Long) As Boolean
   Dim SaveRow As Long, SaveCol As Long
      With Flex
         .Redraw = False
         SaveRow = .Row
         SaveCol = .Col
         .Row = Row
         .Col = .Col
         'Value checked ?
         FlexCellChecked = (.Text = "a")
         .Row = SaveRow
         .Col = SaveCol
         .Redraw = True
      End With
End Property

Private Sub Command1_Click()
   Dim i As Long
   List1.Clear
      With MSFlexGrid1
         For i = .FixedRows To .Rows - 1
            .Row = i
         List1.AddItem "Row " & i & " Checked: " & FlexCellChecked(MSFlexGrid1, i, 1)
         Next
      End With
End Sub

Private Sub Form_Load()
   Dim i As Long
      With MSFlexGrid1
         .Rows = 5
         .Cols = 5
         .Col = 1
         .ColAlignment(1) = flexAlignCenterCenter
         .ColWidth(1) = 450
         For i = 0 To .Rows - 1
            .Row = i
            .CellFontName = "Marlett"
            .CellFontSize = 20  '<-- to large ?
            If i = 0 Then
               .Text = "a"
            End If
         Next
      End With
End Sub

Private Sub MSFlexGrid1_Click()
      With MSFlexGrid1
         If .Col = 1 Then
            FlexCellChecked(MSFlexGrid1, .Row, .Col) = _
            Not FlexCellChecked(MSFlexGrid1, .Row, .Col)
         End If
      End With
End Sub

I think the question was about this:

[Krool]

Never thought about such possibility.

But I could implement such a 'StateImageSize' property to my ListBoxW control.

So such a property would then apply to a ListBoxW control which 'Style' property is set to '1 - Checkbox' or '2 - Option'.

@Krool---are you referring to Chris, or Inside?

@Inside---what control is that? Code? Properties?

AFAIK, if you are rendering with Themes using UxTheme DrawThemeBackground then Check and Option images are locked to 13 pixels.
Even if you were to grab the 13 pixel image and stretch it, the quality is not that good.

To get around this you can put larger high quality PNG Check and Option image strips containing all states in a resource file and stretch/shrink them in OwnerDraw controls.

Here are some high quality Check and Option image strips that you can use to implement this:

Yes. Just a quick drawn picture with a few labels.
