示例1: GetPreferredWidth
float GetPreferredWidth(const BVariant& value, BView* targetView) const
{
// get the preferred width from the node's designated renderer
if (value.Type() == VALUE_NODE_TYPE) {
ModelNode* node = dynamic_cast<ModelNode*>(value.ToReferenceable());
if (node != NULL && node->GetValue() != NULL
&& node->TableCellRenderer() != NULL) {
return node->TableCellRenderer()->PreferredValueWidth(
node->GetValue(), targetView);
}
}
return fColumn.BTitledColumn::GetPreferredWidth(NULL, targetView);
}示例2: DrawValue
void DrawValue(const BVariant& value, BRect rect, BView* targetView)
{
// draw the node's value with the designated renderer
if (value.Type() == VALUE_NODE_TYPE) {
ModelNode* node = dynamic_cast<ModelNode*>(value.ToReferenceable());
if (node != NULL && node->GetValue() != NULL
&& node->TableCellRenderer() != NULL) {

targetView);
return;
}
}
// fall back to drawing an empty string
fField.SetString("");
fField.SetWidth(Width());
fColumn.DrawField(&fField, rect, targetView);
