columnheader

问题 Is there a chance to set the header of the data file columns as label (not as key)? I have data files with 5 or 6 columns and a header above each column. Now I would like to use the columnheader with the set label command. Is this possible? 回答1: On a unixoid system, the head command helps: header = system("head -n 1 ".filename) label1 = word(header,1) label2 = word(header,2) ... set label 1 at 0.5,0.5 label1 set label 2 .... MS win does not have the head command, you might use 'findstr /B \"#

问题 I have a WinForms .NET datagrid whose data source is a List<cLineItem> called lines. cLineItem is very simple class with properties like units (int), description (string) and unit amount (float).

问题 I have a ListView (GridView) in WPF and I'm trying to implement sorting according to http://msdn.microsoft.com/en-us/library/ms745786.aspx.

问题 I've been trying to find out a way to read data from the selected ListView row and display each value in their respected TextBox for easy editing. The first and easiest way would be something like this: ListViewItem item = listView1.SelectedItems[0]; buyCount_txtBox.Text = item.SubItems[1].Text; buyPrice_txtBox.Text = item.SubItems[2].Text; sellPrice_txtBox.Text = item.SubItems[3].Text; There is nothing wrong with that code but I have around 40 or more TextBoxes that should display data.

问题 How could I make the Datagrid display the headers in case there's no row to display? My Datagrid is "completely" read-only with: "AutoGenerateColumns ="True" "CanUserAddRows="False" "CanUserDeleteRows="False" "CanUserResizeRows="False" "IsReadOnly"="True" If there's no row, then the headers aren't displayed, if I add even an empty row, then the headers are shown! Until now, I couldn't find any workaround/solution for that! Thx all Fred 回答1: AFAIK If there are no rows then there are no columns

问题 I want to merge(span) horizontal headers in QTableWidget . I tried googling for the same, but no luck and hence posting it. Please guide me. 回答1: You can subclass QHeaderView and create one section for each of the groups of columns/rows you would like to span and connect signals and slots to have them react to the different columns/rows. The following example is for spanning the horizontal header: #include <QtGui> class MyHeaderModel : public QAbstractItemModel { public: MyHeaderModel(QObject
