I'm kinda new to Palm programming and have been stuck on this bug for a long
time. Any leads would be much appreciated.
I have a four column table, and I want all columns except the first (left)
one to be editable, so I made the left column a non-editable customTableItem
and the other three textTableItems with a load procedure. It works fine,
except somehow the data for the first column becomes garbage characters
instead of text when I use any of the three editable columns. (Specifically,
when I enter, then exit, one of those cells.) I've been stuck on this for a
long time. Does anyone know what could do this? The table initialization and
load procedure are below.
// Draw exercise & set info in the WSTable
static void drawWorkoutSheetTable( void )
{
FormPtr form;
TablePtr table;
Int column;
Int count;
form = FrmGetActiveForm();
// Get the table pointer
table = getObject( form, WorkoutSheetTableTable );
// First column is always usable & takes a custom draw procedure
TblSetCustomDrawProcedure( table, 0, drawWSTNameCell );
TblSetColumnUsable( table, 0, true );
// The remaining 3 columns use the custom load procedure
for( column = 1; column < WS_TABLE_NUM_COLUMNS; column++ )
{
TblSetLoadDataProcedure( table, column, loadWSTSetCell );
TblSetColumnUsable( table, column, true );
}
// For all rows: Initialize the table styles
for( count = 0; count < WS_TABLE_NUM_ROWS; count++ )
{
// If there is data for the row, make it usable & set cell styles
if( tableRowIndex[count] != 0xffff )
{
TblSetRowUsable( table, count, true );
TblSetItemStyle( table, count, 0, customTableItem ); // first column is
custom item
// Set the non-left cell styles to textTableItem
for( column = 1; column < WS_TABLE_NUM_COLUMNS; column++ )
{
TblSetItemStyle( table, count, column, textTableItem );
}
}
else
// Hide any unused rows
TblSetRowUsable( table, count, false );
}
TblDrawTable( table );
return;
}
static Err loadWSTSetCell( VoidPtr table, Word row, Word column,
Boolean editable, VoidHand * dataH, WordPtr dataOffset,
WordPtr dataSize, FieldPtr fld )
{
Int record;
Int set;
record = tableRowIndex[row];
set = tableColumnIndex[column];
*dataH = DmQueryRecord( reflexDB, record );
*dataOffset = DB_NUM1_START_OF1 + ( set - 1 ) * DB_SET_SIZE;
*dataSize = MemHandleSize( *dataH );
return (0);
}
