示例1: createComboBox
private Control createComboBox(Question q)
{
FlowLayoutPanel pnlInner = new FlowLayoutPanel();
pnlInner.FlowDirection = FlowDirection.LeftToRight;
int innerPanelLength = 0;
//如果 Question 有 Label ，則要在前面加上 Label
if (q.HasLabel)
{
Label lbl = this.createLabel(q.GetQuestionLabel());
pnlInner.Controls.Add(lbl);
innerPanelLength += lbl.Width + 6;
}
//create combobox
ComboBoxEx cbo = new ComboBoxEx();
