From c9097836306c3946917e22ac4bfc6141f89ad5ad Mon Sep 17 00:00:00 2001 From: Michael Bedward Date: Fri, 28 Jul 2000 05:12:32 +0000 Subject: [PATCH] Renamed existing wxGrid::SelectBlock to HighlightBlock. Added new wxGrid::SelectBlock that does what the name suggests (consistent with the other SelectXXX functions). git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@7890 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775 --- include/wx/generic/grid.h | 15 +- src/generic/grid.cpp | 295 ++++++++++++++++++++------------------ 2 files changed, 166 insertions(+), 144 deletions(-) diff --git a/include/wx/generic/grid.h b/include/wx/generic/grid.h index 02ae366dc7..3fc9dfb640 100644 --- a/include/wx/generic/grid.h +++ b/include/wx/generic/grid.h @@ -1300,12 +1300,15 @@ public: void SelectRow( int row, bool addToSelected = FALSE ); void SelectCol( int col, bool addToSelected = FALSE ); - void SelectBlock( int topRow, int leftCol, int bottomRow, int rightCol ); + void SelectBlock( int topRow, int leftCol, int bottomRow, int rightCol, + bool addToSelected = FALSE ); void SelectBlock( const wxGridCellCoords& topLeft, - const wxGridCellCoords& bottomRight ) + const wxGridCellCoords& bottomRight, + bool addToSelected = FALSE ) { SelectBlock( topLeft.GetRow(), topLeft.GetCol(), - bottomRight.GetRow(), bottomRight.GetCol() ); } + bottomRight.GetRow(), bottomRight.GetCol(), + addToSelected ); } void SelectAll(); @@ -1734,6 +1737,12 @@ protected: void SetCurrentCell( int row, int col ) { SetCurrentCell( wxGridCellCoords(row, col) ); } + void HighlightBlock( int topRow, int leftCol, int bottomRow, int rightCol ); + + void HighlightBlock( const wxGridCellCoords& topLeft, + const wxGridCellCoords& bottomRight ) + { HighlightBlock( topLeft.GetRow(), topLeft.GetCol(), + bottomRight.GetRow(), bottomRight.GetCol() ); } // ------ functions to get/send data (see also public functions) // diff --git a/src/generic/grid.cpp b/src/generic/grid.cpp index 138c06e72c..7930995a2b 100644 --- a/src/generic/grid.cpp +++ b/src/generic/grid.cpp @@ -4674,17 +4674,17 @@ void wxGrid::ProcessGridCellMouseEvent( wxMouseEvent& event ) { if ( m_selectingKeyboard == wxGridNoCellCoords) m_selectingKeyboard = coords; - SelectBlock ( m_selectingKeyboard, coords ); + HighlightBlock ( m_selectingKeyboard, coords ); } else { if ( !IsSelection() ) { - SelectBlock( coords, coords ); + HighlightBlock( coords, coords ); } else { - SelectBlock( m_currentCellCoords, coords ); + HighlightBlock( m_currentCellCoords, coords ); } } @@ -4816,7 +4816,7 @@ void wxGrid::ProcessGridCellMouseEvent( wxMouseEvent& event ) SetCurrentCell( coords ); if ( m_selection->GetSelectionMode() != wxGrid::wxGridSelectCells) - SelectBlock( coords, coords ); + HighlightBlock( coords, coords ); } m_waitForSlowClick = TRUE; } @@ -5625,6 +5625,141 @@ void wxGrid::SetCurrentCell( const wxGridCellCoords& coords ) } +void wxGrid::HighlightBlock( int topRow, int leftCol, int bottomRow, int rightCol ) +{ + int temp; + wxGridCellCoords updateTopLeft, updateBottomRight; + + if ( m_selection->GetSelectionMode() == wxGrid::wxGridSelectRows ) + { + leftCol = 0; + rightCol = GetNumberCols() - 1; + } + else if ( m_selection->GetSelectionMode() == wxGrid::wxGridSelectColumns ) + { + topRow = 0; + bottomRow = GetNumberRows() - 1; + } + if ( topRow > bottomRow ) + { + temp = topRow; + topRow = bottomRow; + bottomRow = temp; + } + + if ( leftCol > rightCol ) + { + temp = leftCol; + leftCol = rightCol; + rightCol = temp; + } + + updateTopLeft = wxGridCellCoords( topRow, leftCol ); + updateBottomRight = wxGridCellCoords( bottomRow, rightCol ); + + if ( m_selectingTopLeft != updateTopLeft || + m_selectingBottomRight != updateBottomRight ) + { + // Compute two optimal update rectangles: + // Either one rectangle is a real subset of the + // other, or they are (almost) disjoint!
