labWindows CVI 的table主要用法.docx

LabWindows/CVI中table的主要用法2016年12月20日 狄阁老Table是在各种开发环境中一个很重要的控件，特别是在测试软件中，table是一个重要的结果显示控件，下面来介绍一下table的主要功能：（最后附有效果视频）一、要使用table首先需要插入行列，插入列的函数：1）int InsertTableColumns (int Panel_Handle, int Control_ID, int Column_Index, int Number_of_Columns, int Cell_Type);例如： InsertTableColumns (panelHandle, PANEL_TABLE, 1, 5, VAL_CELL_STRING);上面是插入5列，每列为string类型；2）int InsertTableRows (int Panel_Handle, int Control_ID, int Row_Index, int Number_of_Rows, int Cell_Type);例如：InsertTableRows (panelHandle, PANEL_TABLE, -1, 1, VAL_CELL_STRING);每次都是从最后一行插入新行；二、设置列首：可以双击table控件，设置列首，这个就固定死了，用代码实现还是比较自由可控的要设置列首，需要将列首设置为可用状态：SetTableColumnAttribute (panelHandle, PANEL_TABLE,columnindex, ATTR_USE_LABEL_TEXT, 1);当有多列要设置，每列需要启用，用一个for循环启用，例如：/启用列名,5列，用个循环将列名启动起来for(i=1;i6;i+) SetTableColumnAttribute (panelHandle, PANEL_TABLE, i, ATTR_USE_LABEL_TEXT, 1);再设置列首名称：例如：15列的列名设置为测试项名称，测试值，理论值，单位，测试结果SetTableColumnAttribute (panelHandle, PANEL_TABLE, 1, ATTR_LABEL_TEXT, 测试项名称);SetTableColumnAttribute (panelHandle, PANEL_TABLE, 2, ATTR_LABEL_TEXT, 测试值); SetTableColumnAttribute (panelHandle, PANEL_TABLE, 3, ATTR_LABEL_TEXT, 理论值); SetTableColumnAttribute (panelHandle, PANEL_TABLE, 4, ATTR_LABEL_TEXT, 单位); SetTableColumnAttribute (panelHandle, PANEL_TABLE, 5, ATTR_LABEL_TEXT, 测试结果);三、设置垂直scroll,SetCtrlAttribute (panelHandle, PANEL_TABLE, ATTR_SCROLL_BARS, VAL_VERT_SCROLL_BAR);四、当table满行时，显示最后插入的一行/获取行数GetNumTableRows (panel, PANEL_TABLE,&row );SetCtrlAttribute (panel, PANEL_TABLE, ATTR_FIRST_VISIBLE_ROW, row);其中，row为最后一行的行号，五、写入数据/设置这一行五列数据SetTableCellVal (panel, PANEL_TABLE, MakePoint(1, row), 传感器的温度值);SetTableCellVal (panel, PANEL_TABLE, MakePoint(2, row), data); SetTableCellVal (panel, PANEL_TABLE, MakePoint(3, row), 290300); SetTableCellVal (panel, PANEL_TABLE, MakePoint(4, row), ); SetTableCellVal (panel, PANEL_TABLE, MakePoint(5, row), state);如果都是同一类型，可以用for循环写入：for(i=1;i6;i+)SetTableCellVal (panel, PANEL_TABLE, MakePoint(i, row), “值”);界面设计：运行后的静态效果：代码设计：/=/ Title: tableExample/ Purpose: A short description of the application./ Created on: 2016-12-20 at 19:45:14 by 狄阁老./ Copyright: .
