Member Function Documentation

void CHexEditCtrl::ChangeEditPos ( long dx, long dy, bool bRepaint = false ) [protected]

Set new edit position after moving caret. Parameters: dx   - horizontal shift of cursor (in numbers), positive - left-hand side, negative - right-hand side direction dx   - vertical shift of cursor (in numbers), positive - downward, negative - upward direction bRepaint   = true - always repaint the control, false - only if scrolling is nesessary

void CHexEditCtrl::ChangeEditPos ( CPoint pt ) [protected]

Set new edit position after mouse click. Parameters: pt   - mouse co-ordinates.

void CHexEditCtrl::ClearSelection ( ) [protected]

Clear selection.

void CHexEditCtrl::DeleteData ( DWORD dwPos, DWORD dwCount = 1 ) [protected]

Delete dwCount numbers (not bytes!) from m_data, starting from dwPos.

void CHexEditCtrl::DeleteSelection ( ) [protected]

Delete currently selected data.

bool CHexEditCtrl::EnterNumber ( ) [protected]

This function is called prior to entering a new number or ascii byte. It does InsertBytes, scrolling and repainting, if nesessary. Returns: false, if it's impossible to insert number because of m_allowChangeSize == false, otherwise - true.

void CHexEditCtrl::InsertData ( DWORD dwPos, DWORD dwCount = 1 ) [protected]

Insert dwCount numbers (not bytes!) in m_data, starting from dwPos.

void CHexEditCtrl::InvalidateEditRect ( long nEditPos ) [protected]

Invalidate rect occupied by number with address nEditPos.

bool CHexEditCtrl::IsSelectionEmpty ( ) [protected]

Returns true, if nothing is selected, and false otherwise.

bool CHexEditCtrl::NormalizeEditPos ( ) [protected]

Update caret position and scroll bars when m_editPos is changed.

void CHexEditCtrl::PlaceCaret ( ) [protected]

Calculate co-ordinates and show caret.

void CHexEditCtrl::RecalcLayout ( ) [protected]

Compute m_editPos, m_viewPos, margins etc. after changing control properties.

void CHexEditCtrl::RecalcSelection ( CPoint point ) [protected]

Update selection margins when the mouse is moving. Parameters: point   mouse co-ordinates.

void CHexEditCtrl::TextOutWithCheck ( CDC * pdc, const CRect & rcInvalid, int x, int y, CString & strText ) [protected]

This function calls pdc->TextOut ( x, y, strText ) function if text overlaps with rcInvalid.

bool CHexEditCtrl::UpdateScrollBars ( ) [protected]

Recalculate scroll ranges and positions of scrollbars, show or hide scroll bars, if nesessary.
