I'm having problems with columninfo. It worked before, but with latest listbrowser gadget updates, it lockes up the system. If i remove it then the program won't lockup the whole system.
Any ideas????

How i set things up.


struct ColumnInfo ci[] =

{



    { 110, "        Movie name", CIF_SORTABLE },

    {   17,  "Year", 0 },

    {   70,  "      Genre", 0 },

    { -1, (STRPTR)~0, -1 }

};



        LAYOUT_AddChild, gadgets[GID_LISTVIEW] = ListBrowserObject,

                                            GA_ID,GID_LISTVIEW,

                                            GA_RelVerify, TRUE,

                                            GA_ReadOnly,FALSE,

                                            LISTBROWSER_SortColumn, 0 ,

                                            LISTBROWSER_Editable, FALSE,

                                        //    LISTBROWSER_ColumnInfo, (ULONG)&ci,

                                            LISTBROWSER_ColumnTitles, TRUE,

                                            LISTBROWSER_Labels,info_liste,   

                                            LISTBROWSER_MakeVisible,1,

                                            LISTBROWSER_ShowSelected, TRUE,

                                            LISTBROWSER_HorizontalProp, FALSE, 

                                        ListBrowserEnd,

Firstly you should always, always allocate ColumnInfo arrays with the AllocLBColumnInfo() function.

Given that you are rolling your own, how is you column info allocated?

Is it declared static ? or on the stack ? If the latter then that's highly likely to be why it goes wrong.

The last element should be {-1, NULL, 0 } but I doubt that would make a difference.

Hi, I use a listbrowser and columninfo like this, hope it helps:


columninfo = IListBrowser->AllocLBColumnInfo(2,

                             LBCIA_Column,0, LBCIA_Title," Keymap", LBCIA_AutoSort,TRUE, LBCIA_Sortable,TRUE,

                             LBCIA_Column,1, LBCIA_Title," Description",

                            TAG_DONE);

..

LAYOUT_AddChild, OBJ(OBJ_LISTBROWSER) = IIntuition->NewObject(NULL, "listbrowser.gadget",

                       GA_ID,                    OBJ_LISTBROWSER,

                       LISTBROWSER_SortColumn,   0,

                       LISTBROWSER_AutoFit,      TRUE,

                       LISTBROWSER_Labels,       &listbrowser_list,

                       LISTBROWSER_ColumnInfo,   columninfo,

                       LISTBROWSER_ColumnTitles, TRUE,

                       LISTBROWSER_ShowSelected, TRUE,

                       //LISTBROWSER_Selected,     -1,

                       LISTBROWSER_MinVisible,   6,

                       LISTBROWSER_Striping,     LBS_ROWS,

                      TAG_DONE),

..

Thanks guys. Sorted it out. just one more question. The columns are locked in their width. Possible to get it to resize the columns when user changes the size of the window?

You are passing a pointer to a pointer (&ci) which is wrong. If it worked before it was dumb luck.

It was my good karma i think.

Have fixed that now. But still need help on the columns widht being locked even when resizing the window.
Looks kinda retarded when everything else changes size except the listbrowser columns.

You are hard coding the widths int the ColumnInfo, try not doing that but setting LISTBROWSER_AutoFit instead. Then enable the horizontal scroll bar.

You will need to resend the AutoFit tag everytime you change the list.

Also ofcourse you can set weights for the column widths rathe than fixed pixels, when creating the columninfo with the allocation function sdee SetLBColumnInfoAttrs autodoc for info.
