Hi every one,
Please help me on that problem, it's so difficult for me to solve:
int main(int argc, char** argv){ QApplication qapp(argc, argv);
KComponentData cd("graphicsview-test"); Calligra::Tables::Doc doc;
bool ok = doc.*openUrl*(KUrl("/home/excel_samples/Cash_Flow_Projection_Worksheet.xls"));
if (!ok) { qDebug() << "failed to load"; return 0;
} QFont font(KoGlobal::defaultFont());
Calligra::Tables::CanvasItem* canvas = new
Calligra::Tables::CanvasItem(&doc); QRect usedArea =
canvas->*activeSheet*()->usedArea(true); QSizeF
size(canvas->*activeSheet*()->columnPosition(usedArea.right()+3),
canvas->*activeSheet*()->rowPosition(usedArea.bottom()+5));
canvas->setDocumentSize(size); size =
canvas->*zoomHandler*()->*documentToView*(size);
canvas->resize(size); canvas->setPos(0, 0);
Calligra::Tables::ColumnHeaderItem* columnHeader =
static_cast<Calligra::Tables::ColumnHeaderItem*>(canvas->*columnHeader*());
static_cast<QGraphicsWidget*>(columnHeader)->resize(size.width(),
canvas->*zoomHandler*()->zoomItY(font.pointSizeF() + 3));
columnHeader->setPos(0, -columnHeader->height());
Calligra::Tables::RowHeaderItem* rowHeader =
static_cast<Calligra::Tables::RowHeaderItem*>(canvas->*rowHeader*());
static_cast<QGraphicsWidget*>(rowHeader)->resize(canvas->*zoomHandler*()->zoomItX(YBORDER_WIDTH),
size.height()); rowHeader->setPos(-rowHeader->width(), 0);
columnHeader->toolChanged("PanTool");
rowHeader->toolChanged("PanTool"); QGraphicsScene scene;
scene.addItem(canvas); scene.addItem(columnHeader);
scene.addItem(rowHeader); QGraphicsView view(&scene);
view.show(); qapp.exec();}
This portion of code can run and show a excel file. But when I try using
function: doc.createView().show, only tabbars and scrollbars shown. Sheet
area is completely black. I try using canvas, canvasWidget and
canvasController but it isn't successful.
Anyone can show me why it is and how to render the view to an image ?
