I've upgraded my application from XTP 9.60 to 10.20 (XTP 2006 Q2) and now it gets an exception because of the following code (which used to work fine):

SetTheme(xtpTaskPanelThemeCustom);

SetCustomTheme(new CCustomTaskPanelTheme));

Where CCustomTaskPanelTheme is derived from CXTPTaskPanelExplorerTheme

The exception is in file XTPTaskPanelPaintManager.cpp (1157):

int nAlpha = pGroup->IsExpanding() ? (255 * rc.Height()) / pGroup->GetExpandedClientHeight() : 255;

I'll appreciate any help.

Irit.

Hello,

what inside CCustomTaskPanelTheme?

if you use it in our sample do you see same problme? if you don't use it in your application do you see it?

This is the code (2 functions):

CCustomTaskPanelTheme::CCustomTaskPanelTheme()

{

m_bExplorerTheme = true;

m_bBoldCaption = false;

m_bOfficeBorder = true;

m_clrBackground.SetCustomValue(RGB(255,255,255), RGB(255,255,255);

m_bLeftRoundedCorner = true;

m_bOfficeHighlight = true;

m_groupNormal.clrClient.SetStandardValue(RGB(243, 243, 243));

m_groupNormal.clrHead.SetStandardValue(RGB(224, 223, 227));

m_groupSpecial.clrClient.SetStandardValue(RGB(243, 243, 243));

m_groupSpecial.clrHead.SetCustomValue(RGB(0, 44, 151), RGB(196, 218, 50));

m_groupSpecial.clrHeadTextHot = m_groupSpecial.clrHeadTextNormal;

RefreshMetrics();

}

void CCustomTaskPanelTheme::RefreshMetrics()

{

CreateGripperBitmaps();

}

As to your other 2 questions:

I didn't try using this in your application.

If I remove the call then I don't get exception, but the application looks bad (obviously).

Hi,

Try move code from constructor to refreshmetrics and call base class refreshmetrics:

class CCustomTaskPanelTheme : public CXTPTaskPanelExplorerTheme
{
public:
CCustomTaskPanelTheme();
void RefreshMetrics();
};

CCustomTaskPanelTheme::CCustomTaskPanelTheme()
{

}

void CCustomTaskPanelTheme::RefreshMetrics()

{
CXTPTaskPanelExplorerTheme::RefreshMetrics();

m_bExplorerTheme = true;

m_bBoldCaption = false;

m_bOfficeBorder = true;

m_clrBackground.SetCustomValue(RGB(255,255,255), RGB(255,255,255));

m_bLeftRoundedCorner = true;

m_bOfficeHighlight = true;

m_groupNormal.clrClient.SetStandardValue(RGB(243, 243, 243));

m_groupNormal.clrHead.SetStandardValue(RGB(224, 223, 227));

m_groupSpecial.clrClient.SetStandardValue(RGB(243, 243, 243));

m_groupSpecial.clrHead.SetCustomValue(RGB(0, 44, 151), RGB(196, 218, 50));

m_groupSpecial.clrHeadTextHot = m_groupSpecial.clrHeadTextNormal;

CreateGripperBitmaps();

}

At least this code works with TaskPanel sample...

You never call base RefreshMetrics so caption font was not created...
