For what added const? (everywhere where it is called, it is not const) I overload CXTPReportRecordItem::GetTooltip() and I can not call from it GetCaption for example  ------------- Xtreme ToolkitPro v13.1.0, static, VC++6 |

Why "added" -
ver 12.1:
//-----------------------------------------------------------------------
// Summary:
// Returns the text tool tip for the item
// Returns:
// The text tool tip for the item.
//-----------------------------------------------------------------------
virtual CString GetTooltip() const;
//-----------------------------------------------------------------------
// Summary:
// Call this member to set/change the item tool tip.
// Parameters:
// lpszTooltip - Tool tip of the item
//-----------------------------------------------------------------------
virtual void SetTooltip(LPCTSTR lpszTooltip); ------------- Mark Doubson, Ph.D. |

My question is: why "const"? ------------- Xtreme ToolkitPro v13.1.0, static, VC++6 |

Because GetTooltip does not change the content of the class! Take a look at good C++ books about 'const correctness', e.g. 'Exeptional C++'... If you really need a non-const version, you can cast the const away (const_cast<>), but this is not recommended. ------------- Martin Product: Xtreme Toolkit v 19.0.0, new Projects v 19.1.0 Platform: Windows 10 v 1909 (64bit) Language: VC++ 2017 |

Martin, I know that this is not recommended (I am a little know C++  ) - Because of this I made a post on this forum. Who said that GetTooltip does not change the content of the class? It is virtual and i want to change the content! Does GetCaption change the content of the class? But it is not const! I only told library's developers about the architectural limitations. ------------- Xtreme ToolkitPro v13.1.0, static, VC++6 |
