Qtextbrowser and using rendering
-
hello
im an entry level programmer and new to QT also so im still getting my way around this stuff. I have a program where i am trying to print a pdf and in this pdf i wanna show a table and image graph or render a graph to be exact. so far i get my text table but my image wont show and it only shows one page. So far i have tried QpaintEditor and QImagetext, being i might have not set them up properly so and help would be amazing.so this is how i set up my pdf and how i set up the table that works you can see my attempt to use QImageText
@void MainWindow::QTableWidget2QTextBrowser(QTableWidget *tabW,QTextBrowser *editor)
{
///creates writing format
QTextCharFormat NormalFormat;
editor->setCurrentCharFormat(NormalFormat);//create pointer to current cursor location QTextCursor cursor =editor->textCursor(); cursor.beginEditBlock(); QTextTableFormat tableFormat; tableFormat.setAlignment(Qt::AlignLeft); tableFormat.setBackground(QColor("#ffffff")); tableFormat.setCellPadding(3); tableFormat.setCellSpacing(3); QTextTable *tab=cursor.insertTable(tabW->rowCount()+1,tabW->columnCount(),tableFormat); QTextFrame *frame=cursor.currentFrame(); QTextFrameFormat frameFormat=frame->frameFormat(); frameFormat.setBorder(0); frame->setFrameFormat(frameFormat); QTextCharFormat format_entete_tab; format_entete_tab.setFontPointSize(12); format_entete_tab.setFontWeight(QFont::Bold); QTextCharFormat format_cellule; format_cellule.setFontPointSize(11); for(int i=0;i<tabW->columnCount();i++) { QTextTableCell titre = tab->cellAt(0,i); QTextCursor cellCursor=titre.firstCursorPosition(); cellCursor.insertText(tabW->horizontalHeaderItem(i)->text(),format_entete_tab); } QTextTableCell cell; QTextCursor cellCursor; for(int row=1;row<tab->rows();row++) { for(int col=0;col<tab->columns();col++) { cell=tab->cellAt(row,col); cellCursor=cell.firstCursorPosition(); cellCursor.insertText(tr("%1").arg(tabW->item(row-1,col)->text()),format_cellule); } } cursor.endEditBlock();
}@
This is the problem
@// // Print Graph//// QwtPlotRenderer renderer;
//// renderer.setDiscardFlag(QwtPlotRenderer::DiscardBackground,false);
//// renderer.setLayoutFlag(QwtPlotRenderer::KeepFrames,true);
//// renderer.render(m_plot,&painter,QRect(0,printer->height()/2,printer->width(),printer->height()/2.2));
//// printer->newPage();
@and this is how i set up my my QtextBrowser if there is an error here to in my setup please say so i need to learn.
@void MainWindow::QTableWidget2QTextBrowser(QTableWidget *tabW,QTextBrowser *editor)
