Custom QTableView

Tikani

Hi!
Are there any ways to get such a QTableView? I need independent sub-tables ("independent" in sense of separate indexing and adding new rows from separate models), but these sub-tables must share common columns
QTableViews

Hi,

Do you mean you would have something like 3 different QTableView glued to each other in order to show the information you want ?

Do you mean something like this? https://api.kde.org/frameworks/kitemmodels/html/classKConcatenateRowsProxyModel.html

@SGaist
Yes, something like that. These QTableViews must have the same columns but the horizontal rows (without cells) with titles are mandatory. And it could be a totally different number of rows in the each 'glued' QTableViews. I can't even imagine how to implement it.

VRonin

create the 3 table models
create 2 table models with the same number of columns but just 1 row, fill element 0,0 of these models with the title
use KConcatenateRowsProxyModel and add the 5 models in the order they should appear
use QTableView::setSpan to make the the headers span multiple columns

Alternatively:

create 3 QTableView, one for each model
set their size policy as QSizePolicy::Minimum and disable the scrollbars
lay them out in QWidget with a QVBoxLayout with no margins or borders
add the widget to a QScrollArea

Maybe :) but i don't know how to insert sub-titles to its places like in the picture above. This complex table is a reflection of badly structured paper utility bill and the customer wants total correspondence. :(

@Tikani said in Custom QTableView:

how to insert sub-titles

QAbstractItemModel* model = new QStandardItemModel(this);
model->insertCoulmns(0,4);
model->insertRows(0,5);
model->setData(model->index(0,0),QStringLiteral("Subtitle"));
for(int j=1;j<5;++j){
for(int i=0;i<4;++i){
model->setData(model->index(j,i),QString::number(j) + ','+QString::number(i)); 
}}
QTableView* view=new QTableView(this);
view->setModel(model);
view->setSpan(0,0,1,4);
view->horizontalHeader()->hide();
view->verticalHeader()->hide();
