Not being able to use the widget framework to easily expand the capability of QAbstractItemView is disappointing, but this is probably a side effect of trying to keep views fast. If you do not do data update this way we are talking about completely unrelated widgets with their own data management and have to handle them separately. Simplest way to achieve this would be setIndexWidget. My approach was as follows:. Course prerequisites include solid experience in another programming language, such as Python, C, Java or Visual Basic.

QicsTable (Page 1) | ICS
Setting many cells to have delegates can be expensive. Here you can see I've dragged the "enabled" column to the right, and it's pulled the 3rd level "size" along with it, leaving a bunch of "blank" columns between "route" and "size": Each row is forced to be vertically aligned The standard column headers of the QTreeView are left blank, but visible, to allow column resizing and dragging to reposition.
You can qicsable a proxy model to split your hierarchical model to as many table-like data layouts as you wish. Who says it can't? Why choose ICS for Qt development?

I recently solved a similar problem: QItemDelegate will do display it for you - it will create a widget for a single cell, resize it to proper size, place it at proper location. I think it went free and LGPL a few years ago. This is tedious, but works with enough patience.

If you do not do data update this way we are talking about completely unrelated widgets with their own data management and have to handle them separately.
Just as you mentioned, I have created a QTreeView where I insert a fake row which serves as labels for each level in the hierarchy. We've built appealing user experiences for everything from medical devices to self-driving autos to commercial restaurant equipment.

I'd like the Qt docs to include a comment about openPersistentEditor on the QStyledItemDelegate page, that would have saved me a lot of time. My approach was as follows:. I don't think this will work, as according to the documentation. Loading More Posts 9 Posts.
Individual or small-group mentoring, which qicsttable a more personal approach than our training workshops. You cannot reposition a column by dragging its label, you have to drag the blank column headers at the top You cannot drag a column to re-order it in one level of the tree without moving the lower-level columns.
The approach I took should work for any complex widget.
There's an official example: Only users with topic management privileges can see it. Here you can see I've dragged the "enabled" column to the right, and it's pulled the 3rd level "size" along with it, leaving a bunch of "blank" columns between "route" and "size":. You could also try QicsTable google it. All of these issues I've mentioned would be qivstable by having each level in the tree represented as a separate table.
This can be done in one of two methods: There are several downsides to this approach: I guess I thought it would be better to find something which fits into the Qt ecosystem a bit more harmoniously.
