Adding Multi-Row Tabs Author: Mike Palmatier Posted: May 3, 2008

Environment:Visual C++ 6.0

The TabControl can display more than one row of tabs by using the SetLayout method to apply the xtpTabLayoutMultiRow flag. The number of rows is automatically set by the width and number of the tabs. The number of rows can change if the control is resized, which ensures that the tabs wrap to the next row. If the tab layout is not set to

xtpTabLayoutMultiRow, and the last tab exceeds the width of the control, left and right arrow buttons are added at the right end of the TabControl.

'The TabControl can display more than one row of tabs

'by changing the Layout to xtpTabLayoutMultiRow.

m_wndTabControl.GetPaintManager()->SetLayout(xtpTabLayoutMultiRow);

The m_bMultiRowJustified property specifies the justification of the tabs in the TabControl. When True, each tab is wide enough to accommodate its caption and, if needed, the width of each tab is increased so that each row of tabs spans the width of the TabControl. This will stretch each row of tabs to fill the entire width of the TabControl.

If False, the tab rows will be non-justified. Each tab is just wide enough to accommodate its caption. The rows are not justified, so multiple rows of tabs are \ 'The MultiRowJustified property specifies the 'justification of the tabs in the TabControl.

m_wndTabControl.GetPaintManager()->m_bMultiRowJustified = TRUE;

The m_bMultiRowFixedSelection property specifies whether the the row of the currently selected tab will be moved to the front of the tab rows. This determines how

remaining rows of tabs in front of a selected tab are repositioned.

When False, the rows of tabs in front of the selected tab are repositioned at the opposite side (behind) of the control. For example, if there are three rows in the multi-row tab-control, and a tab in the second row is selected, all tab rows will be repositioned behind the second row.

When True, the rows in a multi-row tab control remain \remaining rows of tabs in front of a selected tab will not be repositioned. For example, if there are three rows in the multi-row tab-control, and a tab in the second row is selected, the tab rows will remain the same.

Adding Multi-Line Items Author: Mike Palmatier Posted: May 3, 2008 Environment:Visual C++

Each property grid item can display multiple lines of text. To enable multi-line support, use the SetMultiLinesCount method of the item to specify a number greater than 1.

VariableItemsHeight must also be True to see multi-line text values in the property grid.

To specify that only one line of text can be displayed (default), set the multi-line count to 1. Start by adding a category to the property grid. CXTPPropertyGridItem* pMetrics =

m_wndPropertyGrid.AddCategory(_T(\Now enable multi-line items by setting SetVariableItemsHeight to TRUE. m_wndPropertyGrid.SetVariableItemsHeight(TRUE);

Then add a PropertyItemString item with the multi-line text. Text will wrap if too long to display in the item. You can use line breaks and carriage returns to specify exactly where the line will break.

CXTPPropertyGridItem* pItem =

pMetrics->AddChildItem(new

CXTPPropertyGridItem(_T(\

_T(\ Morrice, Michigan 48857 USA\

If you will allow your users to edit the multi-line item then you need to specify how the

item will be formatted when the item is in edit mode. The SetEditStyle method specifies how the item behaves when the item is in edit mode.

pItem->SetEditStyle(ES_MULTILINE | ES_AUTOVSCROLL);

Finally you must set how many lines the item will be. The item will always be the number of lines in SetMultiLinesCount regardless of how many lines of text there are. pItem->SetMultiLinesCount(5);
