Oleg,

I'm not sure what you mean. Do you mean that toolbars on dialogs don't use CImageLists? I tried creating a dummy toolbar with one button and doing what you mentioned, but got the same result.

For some weird reason, "Large" icons display the correct buttons, but the customize box doesn't seem to send my dialog a message telling me it's time to resize and reposition everything.

Thanks!

Sstar9, the problem gets even worse if you have created a new toolbar via customization!

Oleg's solution works for me. I do have to call Redraw.

CXTPCommandBar *pToolBar = (CXTPToolBar*)pCmdUI->m_pOther;
pToolBar->Redraw();

I had actually come up with a solution very similar to Oleg's but I washoping for a better solution. Having to add copies of my tools in theresources seems like a bit of a work-around.

So Oleg, if you can keep this problem on a wish list or something that would be good.

Oh, final tidbit. None of this is necessary if the toolbars arecustomized to the Large Icons. It just simply works! Go figure. I thinkthe tools must be automatically refreshing when they are at this size(perhaps this needs to be done when they are not large as well...).

Hi,

You can create new toolbar with only one icon. and call

XTPImageManager->SetIcons(ID_MyToolbar_withIconINeed) .

In my Case, What Oleg suggested does work. By calling the XTPImageManager->SetIcons(ID_MyToolbar) first and then call the MyButton->SetColorWidth() again. I can reset the Toolbar button's icon to its default as in the Remource and redraw the color bar.

But one problem with the solution is by calling the XTPImageManager->SetIcons(ID_MyToolbar), all the control buttons' icons get updated to its default. But in my case, I just want to Update one. I am not sure if there is better solution than calling XTPImageManager->SetIcons(ID_MyToolbar) .

I don't think that works, if I understand what you mean.

As an example, in the Custom Themes example I modifiedCCustomThemesView::OnUpdateText so that I did not set the color if Redwas selected. When I select Red nothing happens. I need a way to getthe tool to go back to how it looks in the resources.

void CCustomThemesView::OnUpdateText(CCmdUI* pCmdUI)
{
    CXTPControlPopupColor* pPopup = DYNAMIC_DOWNCAST(CXTPControlPopupColor, CXTPControl::FromUI(pCmdUI));
   if (pPopup)
   {
      if (m_clr != (COLORREF)0x0000FF) // RED
         pPopup->SetColor(m_clr);
   }
   pCmdUI->Enable(TRUE);
}

Can you elaborate on what you are doing?

it have to work. don't call SetColor at all if color is none.

I have a similar problem. With our color tools we want the color bar tobe an empty box when None is selected. So in the RedrawIcon routine Idon't want to draw anything on the tool, but what I end up with is thelast color drawn on the tool. I tried the following as suggested:

pCommandBars->GetImageManager()->SetIcons(IDR_TOOLBAR_COLOR);
pCommandBars->RedrawCommandBars();

But it did not help. I bet I could reproduce the problem by editingCXTPControlPopupColor::RedrawIcon, but I don't want to go to thateffort until I have to.

Any more ideas for a solution? Do I need to do something different to get it redrawn?

Obviously after you draw icon with width = 10 you changed icon and now width 2 can't be used for this icon. As solution you can reload this icon from original resource(bitmap or ico file)

pCommandBars->GetImageManager()->SetIcons(...);

I wanted to create a popup control which is similar to CXTPControlPopupColor. Note the small color bar at bottom of the CXTPControlPopupColor Icon could be updated by calling its SetColor(nColor) function. Now I wanted it add one more parameter, nWidth, to this function, so that the Color bar's thickness could be updated as well. To do this, I created a derived a class from CXTPControlPopup, the code is something like below.

// in MyControlPopupColor.h

class CMyControlPopupColor : public CXTPControlPopup
{

...

public:

void SetColorWidth(COLORREF clr, int nWidth);

private:

void RedrawIcon(CXTPImageManagerIcon* pImage, CXTPImageManagerIconHandle* hIcon );

private:

COLORREF m_clr;
int m_nWidth;

...

}

//in MyControlPopupColor.cpp

//SetColorWidth function

void CMyControlPopupColor::SetColorWidth(COLORREF clr, int nWidth)
{
if (clr != m_clr)
{
m_clr = clr;

if (nWidth < 1)
   m_nWidth = 1;
  else if(nWidth > 10)
   m_nWidth = 10;
  else
   m_nWidth = nWidth;

  CXTPImageManagerIconSet* pIconSet = GetImageManager()->GetIconSet(GetIconId());
  if (pIconSet)
  {
   pIconSet->RefreshAll();

CXTPImageManagerIconSet::CIconSetMap* pMap = pIconSet->GetIcons();

   POSITION pos = pMap->GetStartPosition();
   UINT nWidth;
   CXTPImageManagerIcon* pImage;
   while (pos != NULL)
   {
    pMap->GetNextAssoc(pos, nWidth, pImage);

CXTPImageManagerIconHandle hIcon;
RedrawIcon(pImage, &hIcon);

    if (!hIcon.IsEmpty())
    {
     pImage->SetIcon(hIcon);
    }
   }
   RedrawParent();
  }
}
}

//RedrawIcon function

void CMyControlPopupColor::RedrawIcon(CXTPImageManagerIcon* pImage, CXTPImageManagerIconHandle* pHandle)
{
CXTPImageManagerIconHandle& hIcon = pImage->GetIcon();

if (hIcon.IsEmpty())
return;

if (!hIcon.IsAlpha())
{
ICONINFO info;

  if (GetIconInfo(hIcon.GetIcon(), &info))
  {
   {
    CXTPCompatibleDC dc(NULL, CBitmap::FromHandle(info.hbmColor));
    CXTPCompatibleDC dcMask(NULL, CBitmap::FromHandle(info.hbmMask));

    BITMAP bmp;
    ::GetObject(info.hbmColor, sizeof(BITMAP), &bmp);
    //int nHeight = int((double)bmp.bmHeight / 5);

int nHeight = int(1 + (bmp.bmHeight) / 30.0 * m_nWidth);

    CRect rc(0, bmp.bmHeight - nHeight, bmp.bmWidth, bmp.bmHeight);
    dc.FillSolidRect(rc, m_clr);
    dcMask.FillSolidRect(rc, 1);
   }

*pHandle = CreateIconIndirect(&info);

   ::DeleteObject(info.hbmMask);
   ::DeleteObject(info.hbmColor);
  }
}
else
{
  CDC dcSrc;
  dcSrc.CreateCompatibleDC(NULL);

PBYTE pBits = 0;
PBITMAPINFO pBitmapInfo = 0;

pHandle->CopyHandle(hIcon);

  TRY
  {
   UINT nSize;
   if (!CXTPImageManagerIcon::GetBitmapBits(dcSrc, pHandle->GetBitmap(), pBitmapInfo, (LPVOID&)pBits, nSize))
    AfxThrowMemoryException();

DWORD dwColor = 0xFF000000 | CLR_TO_RGBQUAD(m_clr);
int temp = int (1 + (pBitmapInfo->bmiHeader.biHeight) / 30.0 * m_nWidth);

//int nCount = pBitmapInfo->bmiHeader.biHeight / 5 * pBitmapInfo->bmiHeader.biWidth * 4;
int nCount = temp * pBitmapInfo->bmiHeader.biWidth * 4;

   for (int i = 0; i < nCount; i += 4)
   {
    *LPDWORD(&pBits) = dwColor;
   }

SetDIBits(dcSrc, pHandle->GetBitmap(), 0, pBitmapInfo->bmiHeader.biHeight, pBits, pBitmapInfo, DIB_RGB_COLORS);

  }
  CATCH (CMemoryException, e)
  {
   TRACE(_T("Failed -- Memory exception thrown."));
  }
  END_CATCH

free(pBits);
free(pBitmapInfo);

}
}

//The SetColorWidth(.) function and RedrawIcon(.) functions are slightly modified versions of that in the CXTPControlPopupColor class. I have highlighted my modified code in red.

With the derived class, I found I can change Color bar's width now but there is a problem.

If I call SetColorWidth function twice, first time with thicker width and and second time with a thinner width, e.g.

first time,

pColorControl->SetColorWidth(COLORRED, 10);

second time,

pColorControl->SetColorWidth(COLORRED, 2);

after the second call, the color bar thichness does not reduced to 2. The reason is color bar drawn first time is not removed during the 2nd to the function.

To solve this problem, I have tried to restore the original toolbar control's Icon by calling

pColorControl->Reset();

pColorControl->SetIconId(Orignal_Icon_ID);

before the second call to SetColorWidth(.) function. However, this does not work. I cannot remove previously drawn color bar on the Icon.

Could anybody help by giving some suggestions on how the above code should be modified to achieve the purpose? I would like to use Alpha toolbar icons in my application, hence I don't want the modified control Icon appear in different style from other icons on the Toolbar.
