Hello,
we using Codejock v11.22. Perhaps it was already changed...
or is this code okay?
How can I detect that my docked toolbar is now in floating state in OnSize??
If a user move a dockingable toolbar, following code will be called:
void CXTPDockContext::Move(CPoint pt)
{
...
if (!bDocked && (dwFlags & xtpFlagFloating))
{
if (m_pBar->GetPosition() != xtpBarFloating)
{
pCommandBars->FloatCommandBar(m_pBar);
CSize sz = m_pBar->CalcDynamicLayout(0, LM_HORZ | LM_MRUWIDTH | LM_COMMIT);
m_rectDragFrame = CRect(m_rectDragFrame.TopLeft(), sz);
AdjustRectangle(m_rectDragFrame, pt);
}
EnsureVisible(m_rectDragFrame);
m_pBar->MoveWindow(m_rectDragFrame);
} }
|
[code}
BOOL CXTPCommandBars::FloatCommandBar(CXTPToolBar* pBar)
{
if (!pBar->Create(m_pFrame, TRUE))
{
return FALSE;
}
if (pBar->m_pDockBar != NULL)
{
pBar->m_pDockBar->RemoveCommandBar(pBar);
pBar->m_pDockBar = NULL;
}
pBar->m_barPosition = xtpBarFloating;
return TRUE;
}
[/code]
BOOL CXTPDockBar::RemoveCommandBar(CXTPToolBar* pBar, int nPosExclude)
{
ASSERT_VALID(this);
ASSERT(pBar != NULL);
if (!pBar)
return FALSE;
int nPos = FindBar(pBar, nPosExclude);
ASSERT(nPos > 0);
if (nPos <= 0)
return FALSE;
m_arrBars.RemoveAt(nPos);
if (m_arrBars[nPos-1] == NULL && m_arrBars[nPos] == NULL)
m_arrBars.RemoveAt(nPos);
pBar->m_pDockBar = NULL;
// get parent frame for recalc layout/frame destroy
m_pCommandBars->RecalcFrameLayout(TRUE);
return TRUE;
}
|
void CXTPCommandBars::RecalcFrameLayout(BOOL bDelay)
{
if (m_bRecalcLayout)
return;
if (!m_pFrame->GetSafeHwnd())
return;
CFrameWnd* pFrame = m_pFrame->IsFrameWnd() ? (CFrameWnd*)m_pFrame : NULL;
if (pFrame)
{
if (bDelay)
pFrame->DelayRecalcLayout(FALSE);
else
pFrame->RecalcLayout(FALSE);
}
else
{
CXTPClientRect rc(m_pFrame);
m_pFrame->SendMessage(WM_SIZE, 0, MAKELPARAM(rc.Width(), rc.Height()));
}
}

So I will be notified about a changing layout via OnSize, but I can't realign my controls because I don't have the actual state of Toolbar (it says it is already docked top, left, ...)
I think its wrong to set the new state (blue line) after generating the message WM_SIZE. What do you mean?
Thanks for your opinion.

Hi,
Do you have your toolbars inside some frame or simple dialog?
strange - if its frame last line have not to be executed, if its dialog - toolbar can't be floated.
you can check if pToolBar->GetDockBar() return NULL - it means toolbar is floated.

We use it inside a dialog. And it works fine...
(inclusive floating)
Was it not planned to work inside dialogs???
You have right.
CFrameWnd* pFrame = m_pFrame->IsFrameWnd() ? (CFrameWnd*)m_pFrame : NULL;
|
pFrame is NULL in dialogs, so the else-case is executed.
Your're idea (to check GetDockBar() before I call GetPosition()) I already tried.
But the problem is, so I get an flicker effect!
(try to move a Toolbar inside a command bar. So OnSize will be called twice. First with GetDockBar() == NULL and second with GetDockBar() != NULL)
If I move the line, everything works fine...
BOOL CXTPCommandBars::FloatCommandBar(CXTPToolBar* pBar)
{
if (!pBar->Create(m_pFrame, TRUE))
{
return FALSE;
}
pBar->m_barPosition = xtpBarFloating;
if (pBar->m_pDockBar != NULL)
{
pBar->m_pDockBar->RemoveCommandBar(pBar);
pBar->m_pDockBar = NULL;
}
return TRUE;
}

But I think for compatibility that's the better solution:
BOOL CXTPCommandBars::FloatCommandBar(CXTPToolBar* pBar)
{
if (!pBar->Create(m_pFrame, TRUE))
{
return FALSE;
}
if (pBar->m_pDockBar != NULL)
{
pBar->m_pDockBar->RemoveCommandBar(pBar);
pBar->m_barPosition = xtpBarFloating;
pBar->m_pCommandBars->RecalcFrameLayout(TRUE);
pBar->m_pDockBar = NULL; //Is this neccessery? m_pDockBar will be set to NULL in RemoveCommandBar
}
else
pBar->m_barPosition = xtpBarFloating;
return TRUE;
}

Thats's my code. Or do you have a better way to resolve this problem? 
void CMyDialog::OnSize(UINT nType, int cx, int cy)
{
__super::OnSize(nType, cx, cy);
RepositionBars(AFX_IDW_CONTROLBAR_FIRST, AFX_IDW_CONTROLBAR_LAST, 0);
if (m_TabCtrl.GetSafeHwnd() &&
m_pToolBar && m_pToolBar->GetSafeHwnd())
{
CRect rectClient;
GetClientRect( &rectClient );
CXTPEmptyRect rectToolBar;
if (m_pToolBar->GetPosition() != xtpBarFloating)
m_pToolBar->GetClientRect( &rectToolBar );
switch (m_pToolBar->GetPosition())
{
case xtpBarLeft:
rectClient.left += rectToolBar.Width();
rectClient.right -= rectToolBar.Width();
break;
case xtpBarTop:
rectClient.top += rectToolBar.Height();
rectClient.bottom -= rectToolBar.Height();
break;
case xtpBarRight:
rectClient.right -= rectToolBar.Width();
break;
case xtpBarBottom:
rectClient.bottom -= rectToolBar.Height();
break;
}
m_TabCtrl.MoveWindow( rectClient.left + 8, rectClient.top + 8, rectClient.right - 16, rectClient.bottom - 16 );
}
}

better call
RepositionBars(AFX_IDW_CONTROLBAR_FIRST, AFX_IDW_CONTROLBAR_LAST, 0, reposQuery, rcClientNow);
to get current client rect.

Okay. This code looks nicer.
__super::OnSize(nType, cx, cy);
if (m_TabCtrl.GetSafeHwnd())
{
CRect rcClientNow;
RepositionBars(AFX_IDW_CONTROLBAR_FIRST, AFX_IDW_CONTROLBAR_LAST, 0);
RepositionBars(AFX_IDW_CONTROLBAR_FIRST, AFX_IDW_CONTROLBAR_LAST, 0, reposQuery, rcClientNow);
m_TabCtrl.MoveWindow( rcClientNow.left + 8, rcClientNow.top + 8, rcClientNow.Width() - 16, rcClientNow.Height() - 16 );
}

But this doesn't solve the problem if anyone likes to detect the current state in OnSize of a toolbar? Now, you never get the information about the toobar floating state. But I don't know if anyone would use/is missing this functionality...
