Hello,

I've increased buffer size to 32.

I've modified function as virtual.

Hi,
I probably found a failure in CXTPPropertyGridItemDouble::StringToDouble() method.
With some value where the string is > 20 char, the value we get  is incorrect.

Example:
with "1.3856932626629e-04" no problem the item shows with precision I asked "-1.3857 E-4"
; but same as negative "-1.3856932626629E-04" (21 chars)
get truncated to 20 chars, so "-1.3856932626629E-0" get converted to "-1.3857" losing the exponent.

Looking at the code (version 24.0.0), this buffer of 20 chars looks suspicious.

    char astring[20];
    WideCharToMultiByte(CP_ACP, 0, strValue, -1, astring, 20, NULL, NULL);
    return (double)atof(astring);

from definition of limit of double that goes from -DBL_MIN to DBL_MAX
DBL_MAX 1.7976931348623158e+308
-DBL_MIN -2.2250738585072014e-308

buffer should be at least 25 chars.
you can reproduce the problem with sample app PropertyGrid.PropertyGrid.exe

Can you consider a fix for next release?

Also, as mentioned here
https://forum.codejock.com/cxtppropertygriditemdoublestringtodouble_topic12540_post42376.html?KW=StringTodouble#42376
It could be good to have this method virtual.

Thanks,

Have you tried to use
yourGrid.GetEditOptions()->m_bSelectTextOnEdit = TRUE;

Hallo

Is it possible to 'select' all the text in an inPlaceEdit control, when receiving a grid notification of the above value. I can get a handle to the underlying CEdit control, then using SetSel(0,-1), it momentarily selects the text, but then during the message processing within CJ, the focus is removed and the selection with it.

Any assistance on to how to achieve this?

Anton

Subject: BUG in deprecated xtpGridItemHas* values
Posted: 05 April 2024 at 4:37am

Bug in [Source\PropertyGrid\XTPPropertyGridItem.h]

In v19 we had:

enum XTPPropertyGridItemFlags
{
    xtpGridItemHasEdit           = 1, // Item has an edit control.
    xtpGridItemHasExpandButton = 2, // Item has an expand button.
    xtpGridItemHasComboButton  = 4  // Item has a combo button.
};

In v22 was introduced:

enum XTPPropertyGridItemFlags
{
    xtpPropertyGridItemHasEdit           = 1, // Item has an edit control.
    xtpPropertyGridItemHasExpandButton = 2, // Item has an expand button.
    xtpPropertyGridItemHasComboButton  = 4  // Item has a combo button.
};

//{{AFX_CODEJOCK_PRIVATE
_XTP_DEPRECATED_IN_FAVOR(xtpPropertyGridItemHasEdit)
const XTPPropertyGridItemFlags xtpGridItemHasEdit = xtpPropertyGridItemHasEdit;

_XTP_DEPRECATED_IN_FAVOR(xtpGridItemHasExpandButton) *same; no "..Property.."*
const XTPPropertyGridItemFlags xtpGridItemHasExpandButton = xtpGridItemHasExpandButton;

_XTP_DEPRECATED_IN_FAVOR(xtpGridItemHasComboButton)
const XTPPropertyGridItemFlags xtpGridItemHasComboButton = xtpGridItemHasComboButton;
//}}AFX_CODEJOCK_PRIVATE

As you can see, the Values 2 and 4 had their deprecated entries mixed up and get self-assigned resulting in 0 as values for the old constant names!

Hi;

How can I open the dropdown list of a CXTPPropertyGridItem by code?

Subject: Inconsistent Tooltips for Themed Property Grid
Posted: 24 May 2023 at 12:40pm

I had the same problem and since I was very annoyed I took a look at the code and surprisingly found that theme tooltip support was already in place (CXTPPropertyGridToolTip).

What was missing was drawing tooltips using themes. I then took the code from CXTPGridControl which has the tooltips that work correctly (CXTPGridTip) and copied and adapted the code from the OnPaint method.

For simplicity I report below all the OnPaint code even if the changes are few

void CXTPPropertyGridToolTip::OnPaint()
{
    CPaintDC dc(this);
    CXTPClientRect rc(this);

    dc.SetBkMode(TRANSPARENT);

    BOOL bToolipDrawn = FALSE;
    CWnd* pToolTip = m_pGrid->GetPropertyGrid()->GetToolTipContext()->CreateToolTip(m_pGrid);
    if (NULL != pToolTip)
    {
        pToolTip->SetWindowPos(&CWnd::wndTop, 0, 0, rc.Width(), rc.Height(),
                               SWP_HIDEWINDOW | SWP_NOZORDER | SWP_NOACTIVATE | SWP_NOOWNERZORDER
                                   | SWP_NOREDRAW | SWP_NOMOVE | SWP_NOCOPYBITS);
        bToolipDrawn =
            (TRUE
             == pToolTip->SendMessage(WM_PRINTCLIENT, reinterpret_cast<WPARAM>(dc.GetSafeHdc()),
                                      PRF_CLIENT | PRF_ERASEBKGND | PRF_CHILDREN | PRF_OWNED));
        pToolTip->DestroyWindow();
        delete pToolTip;
    }

    if (!bToolipDrawn)
    {
        m_pGrid->GetPropertyGrid()->GetToolTipContext()->DrawBackground(&dc, rc);
    }

    if ((m_pGrid->GetExStyle() & WS_EX_RTLREADING)
        || (m_pGrid->GetExStyle() & WS_EX_LAYOUTRTL))
    {
        dc.SetTextAlign(TA_RTLREADING);
    }

    CString strText;
    GetWindowText(strText);

    CXTPFontDC font(&dc, &m_xtpFont);
    CRect rcText(rc);
    rcText.left += XTP_DPI_X(4);

    dc.DrawText(strText, rcText, DT_SINGLELINE | DT_VCENTER | DT_NOPREFIX);
}



Not extensively tested but it seems ok to me.
