CTableTextInterpreter


Heritage

Superclass: CTableInterpreter (internal class)

Subclasses: None


Description

This class provides an interpreter for displaying and editing text in table cells. The class supports multi-line compass justification and in-cell editing.


Usage

Table interpreters handle the display of data within a table cell and user interaction with the cell and its data. By default, the table installs a text interpreter. To associate a different type of display (such as a control) to a cell or set of cells, you must create the appropriate interpreter and set it as an attribute on the desired cell, row, column, or table as a whole.

The CTableTextInterpreter displays single and multi-line text in cells and allows the user to edit the text read/write cells.

	CTableAttributes anAttributesSet;
anAttributesSet.Interpreter(
new CTableTextInterpreter(
myTable->GetTableView(), // Owner
TX_BORDER, // Flags to NTextEdit
32, // Right margin
32, // Character limit
NULLcmd, // Enter command
TRUE, // Single line
TRUE // notify of all changes
)
);
anAttributesSet.Interpreter( anInterpreter );
myTable->SetTable(anAttributesSet);

Protected Data Members

static const int kTextLeftMargin; Text margins in pixels from left inside
static const int kTextTopMargin; Text margins in pixels from top
unsigned int itsAttributes; Attributes passed to the NTextEdit constructor
UNITS itsRightMargin; Margin passed to the NTextEdit constructor
int itsCharacterLimit; Character limit passed to the NTextEdit constructor
long itsCommand; Command number passed to the NTextEdit constructor
CStringRW itsInitialString; To reliably detect changes
CNativeTextEdit* itsEdit; Its NTextEdit during in cell editing
BOOLEAN itsSingleLine; TRUE if cells only contain single line text
BOOLEAN itsNotifyAllChanges; TRUE if to notify during typing of cell changes in addition to normal focus changes/enter change notification.
