Creo 二次开发-UI 开发(3)表格-CFANZ编程社区

创建表格

在 UI Editor 中添加表格控件，函数 uifcTableFind()获取表格句柄。

xstring tablename = "table";
uifcTable_ptr table = uifcTableFind(dialogname, tablename);
table->AddActionListener(new MyTableListener());

SetColumnNameArray()、SetColumnTextArray()、SetRowNameArray()、SetRowTextArray()分别添加行列并设置行列名称

xstringsequence_ptr col_title = xstringsequence::create();
xstringsequence_ptr row_title = xstringsequence::create();
for (int i = 1; i <= col_num; i++)
{
    col_title->append(("C" + to_string(i)).c_str());
}
for (int j = 1; j <= row_num; j++)
{
    row_title->append(("R" + to_string(j)).c_str());
}
table->SetColumnNameArray(col_title);
table->SetColumnTextArray(col_title);
table->SetRowNameArray(row_title);
table->SetRowTextArray(row_title);

uifcTableCellFind()和 uifcTableCellLookup()分别根据行列名称和行列索引获取单元格句柄，setText()设置单元格文字。

for (int i = 0; i < col_title->getarraysize(); i++)
{
    for (int j = 0; j < row_title->getarraysize(); j++)
    {
        uifcTableCell_ptr cell = uifcTableCellFind(dialogname, tablename, row_title->get(j), col_title->get(i));
        cell->SetText("test");
    }
}

table 中单元格不支持直接修改，可以通过监听器的 OnActivate()函数执行单元格修改函数，实现单元格修改功能。

void ChangeCellText(uifcTable_ptr handle)
{
    pfcSession_ptr session = pfcGetProESession();
    try
    {
        xstring text = session->UIReadStringMessage(false);
        xstring CellSelected = handle->GetSelectedCellNameArray()->get(0);
        uifcTableCellCoordinates_ptr coor = handle->GetAnchorCellName();
        uifcTableCell_ptr cell = uifcTableCellFind(handle->GetDialog(), handle->GetComponent(),
                                                   coor->GetRow(), coor->GetColumn());
        if (!(text.IsNull() || text == xstring("use_default_string")))
            cell->SetText(text);
        session->UIClearMessage();
    }
    OTK_EXCEPTION_PRINT_LOG
}

监听器函数 OnKeyDown()可以监听按键，通过监听 Delete 键，可以实现删除单元格内容功能

void OnKeyDown(uifcTable_ptr handle)
    {
        uifcKey_ptr keypress = handle->GetKeyPressed();
        try
        {
            switch (keypress->GetId())
            {
            case uifcKEY_DELETE:
                DeleteCellText(handle);
                break;

            default:
                break;
            }
        }
        OTK_EXCEPTION_PRINT_LOG
    }

GetSelectedCellNameArray()按字面意思是获取单元格名称数组，但是单元格本身没有名字，单元格由行列定位，该函数获取的是单元格对应行列的名字。

void DeleteCellText(uifcTable_ptr handle)
{
    xstringsequence_ptr cells = handle->GetSelectedCellNameArray();
    try
    {
        xint num = cells->getarraysize();
        if (num > 0)
        {
            for (int i = 0; i < num / 2; i++)
            {
                uifcTableCell_ptr cell = uifcTableCellFind(handle->GetDialog(), handle->GetComponent(),
                                                           cells->get(2 * i), cells->get(2 * i + 1));
                cell->SetText(xstring(""));
            }
        }
    }
    OTK_EXCEPTION_PRINT_LOG
}
