I have this UITableView (http://imgur.com/3YQzm) that I want to list 3 textfields on each row. The info is stored on a SQLite d/b. The first row I need for titles.
How can I list the info in each row so it looks "nice" (i.e. lined up in columns)? Do I need a custom cell for this?
As far I know, you have to put the labels in the specific locations, so you have to define the coordenates for a nice look. I don't know if you are using a xib file for the cell, but, for this case, is better to use it. In the xib will be easy to set the correct location for your labels.

I have a DataTable that I'm passing to a FlexCel report. It contains a variable number of columns, so I'm using the Full Dataset feature (e.g. <#table_name.*>).
However, only a subset of the fields are dynamically generated (I have a variable number of attachments). The column name for each attachment field starts with a common word (e.g. "Attachment0", "Attachment1", etc).
What I would like to do is output the known finite set of fields and then the variable number of attachments. It would be nice if I could write something like <#table_name.Attachment*> (and <#table_name.Attachment**>). Is there any way in FlexCel Reports I can achieve the same result?
A side benefit to such a solution means that I could keep the formatting for the known/finite set of fields.
Update
I added place holder columns to the document, each with a <#delete column> tag, so that the un-wanted columns/data are removed.
Although this works, it's not ideal. For example, if I want to see how the columns fit in the page width (in print preview), then I need to hide the columns. Then I have to remember to un-hide them again, so other developers can see/understand my handy work.
It would be much more straight forward if I could filter the fields before they're output to the document.
I realised there's an alternate way around this problem. I broke up the data into two sets of data - <#table_name.*> and <#table_name_attachments.*>.
The fixed set of fields are in the first table and the variable set of fields is in the second table (all the "Attachment*" fields). When the report is run, I place them next to each other (in the same order) in the same worksheet. This means I have two table ranges - "_table_name_" and "_table_name_attachments_" on the one sheet.
Now I'm able to run my print preview without hiding/re-showing the columns-to-be-deleted. I've also eliminated human error - it was all to easy to accidentally set the wrong number of padded/delete columns.
Hello
I want to show nodes to the columns, depending on their term.
Is it possible via single view (term with depth arg)?
It will be rather complicated to achieve this result using a single view. On the other hand, you could easily set up Panels and a view pane that gets some arguments from the pane's column container. There you could set the different terms you want to show in that column.
Using QTableView I would like to be able to select multiple cells and change all selected cells at once. How I can do it?
I'm not sure exactly what you mean by "changing" the selected cells (content, formatting, something else?) but I think QTableView::selectedIndexes() (or QTableView::selectionModel() if you need more power) is going to help out. You can loop through the returned indexes and update your underlying model.
If you are using a QSortFilterProxyModel you will have to use the QSortFilterProxyModel::mapFromSource() and related methods to map from the selected cells on your table view to the actual model indexes.
I would like to edit a cell by the row and column indexes so essentially do the following:
advDataGrid[2][3] = "Dogs"
so that I am setting the data grid row 2 and column 3 to Dogs. I cannot for the life of me figure out how to do this!
Side note: I need this because I am trying to allow the user to copy a section of an excel file to a section of an AdvancedDataGrid like Google Docs does. I am using this idea to do it: http://mannu.livejournal.com/348299.html
Thanks! Any help will be greatly appreciated!
In general you want to operate on the dataProvider rather than the presentation (AdvancedDataGrid). So in your case, I would get the item associated with the specified row from your dataProvider and modify whichever element is specified to "Dogs". So something like this: adg.dataProvider[row].someColumnData = "Dogs"
EDIT: "someColumnData" refers to whatever property you have set for the column to display. So when you defined your AdvancedDataGrid's columns, you set the 4th column to use the "someColumnData" property of the items in your dataProvider, and you want to change the value in the 4th column, then you'd set it as described above. Hope that clarifies things.
Flex components are data driven, so you should modify the data provider of the grid.
What if you want to edit specific individual cells, eg I want to to keep running totals of some cells in other cells, IE: as a user edits I update whole columns.
Surely their must be a way to walk the array and get Column4.row6 = something.
My problem is that empty rows (if there are more rows that dataSource items then there are empty rows) look identical to rows binded to dataSource items which are empty (see the difference?).
The only way to know the difference is to hover over them with the mouse, and if they are empty there's no color change, otherwise there's the blue background of the selection..
I want to change the color or in some way hide empty rows, those that are not bound to a dataSource item.
How can I accomplish this?
You can format your DataGrid using ItemRenderer.
The itemRenderer is a display object that get the data from the data provider and display it in the grid.
Writing your own logic can help your specific data display in general. in this case, check for data on the ItemRenderer object creationComplete. it the data is null or empty - display a sign (or whatever).

Enjoy!
I'm not sure if this is exactly what you are looking for but I cut off my rows at the end of my dataprovider like this:
myGrid.rowCount = myDP.length();
This can of course be modified with some simple logic to have min, max, or if it's a data entry type of grid length()+1.
