In the sample there is aCToolBar derived class that overrides LoadToolBar(...) and adds the text to the toolbaraccording to the command id of the button. The text added in the example is the last lineof text from the resource string whose id is the same as the command id of the button. Sofor ID_FILE_NEW we have the standard string "Create a new document\nNew" whichwould give us a button text of "New" where as if we change ID_FILE_NEW to"Create a new document\nNew\nNew File" this will cause "New File" tobe displayed on the toolbar button.<tt><font COLOR="#990000"></p><p></font></tt>After the button text has been added the buttons are resized so that youcan see the text proplerly. The main code for this is as follows:<font COLOR="#990000"><tt></p><pre>BOOL CTextToolBar::LoadToolBar(LPCTSTR lpszResourceName){ BOOL bReturn = CToolBar::LoadToolBar(lpszResourceName); // Check if we loaded the toolbar. if (bReturn == FALSE) return bReturn; // Make it flat. ModifyStyle(0, GetStyle()|TBSTYLE_FLAT); // Set the text for each button CToolBarCtrl& bar = GetToolBarCtrl(); int nIndex = 0; TBBUTTON tb; for (nIndex = bar.GetButtonCount(); nIndex >= 0; nIndex--) { ZeroMemory(&tb, sizeof(TBBUTTON)); bar.GetButton(nIndex, &tb); // Do we have a separator? if ((tb.fsStyle & TBSTYLE_SEP) == TBSTYLE_SEP) continue; // Have we got a valid command id? if (tb.idCommand == 0) continue; // Get the resource string if there is one. CString strText((LPCSTR)tb.idCommand); LPCTSTR lpszButtonText = NULL; CString strButtonText(_T("")); _TCHAR seps[] = _T("\n"); if (!strText.IsEmpty()) { lpszButtonText = _tcstok((LPTSTR)(LPCTSTR)strText, seps); while(lpszButtonText) { strButtonText = lpszButtonText; lpszButtonText = _tcstok(NULL, seps); } } if (!strButtonText.IsEmpty()) SetButtonText(nIndex, strButtonText); } // Resize the buttons so that the text will fit. CRect rc(0, 0, 0, 0); CSize sizeMax(0, 0); for (nIndex = bar.GetButtonCount(); nIndex >= 0; nIndex--) { bar.GetItemRect(nIndex, rc); rc.NormalizeRect(); sizeMax.cx = __max(rc.Size().cx, sizeMax.cx); sizeMax.cy = __max(rc.Size().cy, sizeMax.cy); } SetSizes(sizeMax, CSize(16,15)); return bReturn;}</tt></pre></font><!-- Remember to update this --><p>Last updated: 6 June 1998 </p><hr><!-- Codeguru contact details --><table BORDER="0" WIDTH="100%"> <tr> <td WIDTH="33%"><font SIZE="-1"><a HREF="http://www.codeguru.com">Goto HomePage</a></font></td> <td WIDTH="33%"><p align="center"><font SIZE="-2">⌨️ 快捷键说明
