How to control cell attributes from wxGridTableBase descendant?
I need to control cell attributes directly from successor of wxGridTableBase.
I override GetAttr method and experimenting with different return values of CanHaveAttributes method. Unsuccesfully.

You need to create an wxGridCellAttr instance for each celltype, and return it.

Code: Select all

wxGridCellAttr* DataTable::GetAttr(int row, int col)

	if(col < tcivec.size())
	{
		return tcivec[col]->GetAttr();
	}
	return wxGridTableBase::GetAttr(row,col);
}

Which type of DataTable?
wxGrid?
I understand that need to override GetAtrr method of wxGrid class instead of overrideing of GetAttr of wxGridTableBase class?

No, you need to overwrite the method in the wxGridTable class.

I override this method (see first message). Don't dont work. What I must do except overriding wxGridBase::GetAttr? May be additional activities or sending messages are need ?c

return wxGridTableBase::GetAttr(row,col);

I don't which version of wx you are using. I am on 2.6.3 and there is a bug in the doc which says:

wxGridCellAttr* GetAttr(int row, int col)

when in fact in the sources:

wxGridCellAttr* GetAttr(int row, int col, wxGridCellAttr::wxAttrKind kind)

You need to use this last form.
