Hi Martin and Chris,

could you create a small sample that demonstrates your problem and then attach it to a new ticket or here?

Hi,

One work around I have found, which is not a perfect solution, is to find the deepest leaf in the tree and then add a child record to that leaf (call this pChild for example).

This helps force the column width of the parent record of pChild to be something more appropriate.

Thx, Chris.

Hi, I have a similar issue to this with version 13.4.2.

I have a tree structure that can be up to 4 levels deep, e.g.:


Parent
+- Child1
 +- Child2
  +- Child3
   +- Child4

The issue for me is that after calling BestFit for all columns on a report control, the second column (which is the tree column, is not resized as I would expect. Following is an example screenshot.

Here is the code I'm using to call BestFit


CXTPReportColumns * pColumns = pthis->m_xtFileList.GetColumns();
pthis->m_xtFileList.GetReportHeader()->BestFit(pColumns->GetAt(1));
pthis->m_xtFileList.GetReportHeader()->BestFit(pColumns->GetAt(2));
pthis->m_xtFileList.GetReportHeader()->BestFit(pColumns->GetAt(3));
pthis->m_xtFileList.GetReportHeader()->BestFit(pColumns->GetAt(4));

pthis is a pointer to the current dialog.

And here is the code I'm using to create the columns:


m_xtFileList.AddColumn(new CXTPReportColumn(0, _T("Delete"), 20, TRUE, 0));
m_xtFileList.AddColumn(new CXTPReportColumn(1, _T("Filename"), 250, TRUE));
m_xtFileList.AddColumn(new CXTPReportColumn(2, _T("Type"), 125, TRUE));
m_xtFileList.AddColumn(new CXTPReportColumn(3, _T("Created"), 75, TRUE));
m_xtFileList.AddColumn(new CXTPReportColumn(4, _T("File Size"), 100, TRUE));

m_xtFileList.GetColumns()->Find(2)->SetTreeColumn(TRUE);
m_xtFileList.GetColumns()->Find(0)->GetEditOptions()->m_bAllowEdit = FALSE;
m_xtFileList.GetColumns()->Find(1)->GetEditOptions()->m_bAllowEdit = FALSE;
m_xtFileList.GetColumns()->Find(2)->GetEditOptions()->m_bAllowEdit = FALSE;
m_xtFileList.GetColumns()->Find(3)->GetEditOptions()->m_bAllowEdit = FALSE;
m_xtFileList.GetColumns()->Find(4)->GetEditOptions()->m_bAllowEdit = FALSE;
m_xtFileList.GetColumns()->Find(4)->SetAlignment(xtpColumnTextRight);
m_xtFileList.GetColumns()->Find(4)->SetHeaderAlignment(DT_RIGHT);

m_xtFileList.GetReportHeader()->SetAutoColumnSizing(TRUE);
m_xtFileList.GetReportHeader()->AllowColumnResize(TRUE);
m_xtFileList.GetReportHeader()->AllowColumnRemove(FALSE);
m_xtFileList.GetReportHeader()->AllowColumnReorder(FALSE);
m_xtFileList.SetMultipleSelection(FALSE);
m_xtFileList.FocusSubItems(FALSE);
m_xtFileList.GetPaintManager()->SetColumnStyle(xtpReportColumnOffice2007);
m_xtFileList.Populate();

Hopefully I've not broken any forum rules in this post. Many thanks for any help/advice that can be provided.

Chris.

Hi:

I can't figure out how to use CXTPReportHeader::BestFit() in tree-like control mode. It works very well in simple mode, but in tree-like mode with collapsed nodes the calculated column width is wrong. It seems as if only visible rows are considered.
How can I calculate the required width over all rows whether they are collapsed or not?
First expanding all nodes and then collapsing them again on startup/reload is no option because this would take a long time to process.

TIA
