O.K., I admit defeat. I have been trying for much too long to get
fields in two side-by-side rowcolumn widgets inside a form dialog
to line up. What I'm trying to do is this:
label1 text
label2 text
label3 text
label4 text
label5 toggle
etc..
The problem arises from the fact that the text widgets are larger than
the label widgets. Using ATTACH_OPPOSITE_WIDGET on rowcol1 and rowcol2
didn't work appropriately, so I tried a new tack by computing the y
offset of each label in rowcol1 based on the size of its corresponding
entry in rowcol2. This works when packing is set to PACK_NONE, but I
would like my labels to be on the right hand side of rowcol1. Using
XmPACK_TIGHT breaks my horizontal layout even though the documentation
I have says, "Each entry's position in the major dimension is left
unaltered (for example, XmNy is left unchanged when XmNorientation is
XmVertical); its position in the minor dimension is set to the same value
as the greatest entry in that particular row or column.
Am I missing something obvious? Below is a test program which I've been
using to work on this problem. Is this just a bug in RowColumn or am
I breaking (misinterpreting?) the rules ? Any help is more than
appreciated. I may be willing to give up any future first-born male
children......
Try changing the packing between XmPACK_TIGHT and XmPACK_NONE and you'll
see my dilemma.

My office mate and I are constantly banging our heads against this wall. Although I don't see any feasible way for two RowColumn widgets to line up elements, it does seem reasonable to use one RowColumn, set XmNnumColumns = 2 (in this case), and XmNpacking = XmPACK_TIGHT. Of course this doesn't work because XmNnumColumns is only meaningful when XmNpacking is set to XmPACK_COLUMN. But XmPACK_COLUMN makes all entries the same size, which is obviously not what you want. Enough bitching, here are a couple work arounds: 1. Use a Form. a. Connect the top of the first widget in each column to the FORM and subsequent widgets to the previous widget in that column. b. Connect the left of each widget in the first column to the FORM. c. Connect the right of each widget in the last column to the FORM. c. Connect the bottom of each widget to POSITION and set the bottomPosition to I, where I is it's position in the column (1 = the first element). Setting XmNfractionBase to the Number of rows. d. How you connect the widgets to each other depends on what you want. The about example would probally want to just attach the text widget to the label widget. This is good in that it allows you to leave all the positioning up to Motif, but all those attachments can get pretty gross. It is fairly easy to add things to the bottom. Just remember the last row of elements, so attach the new widgets to them. And increment the XmNfractionBase. It would be a pain to add things in the middle. 2. Use a RowColumn of RowColumns This approach uses a lot of widgets, but it makes it easy to add things in the middle (as well as the bottom). On the down side, it breaks up the logical grouping of columns of data. 3. Use a bulletinBoard. You basicall have to do all your own placement calculations. Very brute force. easy to add things at the bottom. Not a very good approach, unless you just can't use any of the above approaches. I have C source for the first two ways of doing this. Send me mail if you want them. If anyone has a better way, I would be very interested. ----------- Greg Stiehl (gstiehl@convex.com) Convex Computer Corporation

My approach to this has been to make sure that both RowColumns have the same margins and spacing, and that the corresponding widgets in each RowColumn have the same total height, figuring in margins, shadows, fontheight, etc. Then let the RowColumns do the positioning by themselves, and everything lines up. I've appended below a modified version of Mr. Wade's original program, together with a couple of choices of resource specifications that give the desired result. This appears to work in Motif 1.0 and Motif 1.1. I use XmPACK_TIGHT on rowcol1, to force all labels to be full-width, so that entryAlignment of XmALIGNMENT_END is meaningful. I am interested in hearing criticism of this approach, and other ways of achieving the effect. --Larry Baer (baer@adobe.com) Adobe Systems Incorporated ==========================Test.c========================================= #include <Xm/Xm.h> #include <Xm/Form.h> #include <Xm/PushB.h> #include <Xm/ToggleB.h> #include <Xm/Text.h> #include <Xm/Label.h> #include <Xm/Form.h> #include <Xm/RowColumn.h> char *labels[] = { "labelA","labelB","labelC","labelD", "labelE - with this extra garbage" }; char *text[] = { "entryA","entryB","entryC","entryD" }; void popup(widget,client_data,call_data) Widget widget; caddr_t client_data; caddr_t call_data; { XtManageChild((Widget)client_data); } void popdown(widget,client_data,call_data) Widget widget; caddr_t client_data; caddr_t call_data; { XtUnmanageChild((Widget)client_data); } void killit(widget,client_data,call_data) Widget widget; caddr_t client_data; caddr_t call_data; { exit(0); } main (argc,argv) int argc; char *argv[]; { Arg args[5]; Widget root,trigger,dismiss,quit; Widget form,rowcol1,rowcol2,label_widget[5],text_widget[4],toggle; int i,nargs,spacing,height[5],y_offset; XmString item_label; root = XtInitialize(NULL, "Test", NULL, 0, &argc, argv); trigger = XmCreatePushButton(root,"trigger",NULL,0); XtManageChild(trigger); nargs = 0; XtSetArg(args[nargs],XmNmappedWhenManaged,FALSE); nargs++; form = XmCreateFormDialog(root,"form",args,nargs); XtAddCallback(trigger, XmNactivateCallback, popup, (caddr_t) form); nargs = 0; XtSetArg(args[nargs],XmNpacking, XmPACK_TIGHT); nargs++; XtSetArg(args[nargs],XmNorientation,XmVERTICAL); nargs++; XtSetArg(args[nargs],XmNentryAlignment,XmALIGNMENT_END); nargs++; XtSetArg(args[nargs],XmNisAligned,TRUE); nargs++; rowcol1 = XmCreateRowColumn(form,"rowcol1",args,nargs); nargs = 0; XtSetArg(args[nargs],XmNleftAttachment,XmATTACH_WIDGET); nargs++; XtSetArg(args[nargs],XmNleftWidget,rowcol1); nargs++; rowcol2 = XmCreateRowColumn(form,"rowcol2",args,nargs); for (i=0; i<4; i++) { nargs = 0; XtSetArg(args[nargs],XmNvalue,text[i]); nargs++; text_widget[i] = XmCreateText(rowcol2,text[i],args,nargs); } XtManageChildren(text_widget, 4); nargs = 0; item_label = XmStringCreateLtoR("Yes",XmSTRING_DEFAULT_CHARSET); XtSetArg(args[nargs],XmNlabelString,item_label); nargs++; XtSetArg(args[nargs],XmNset,TRUE); nargs++; toggle = XmCreateToggleButton(rowcol2,"toggle",args,nargs); XtManageChild(toggle); XtManageChild(rowcol2); nargs = 0; XtSetArg(args[nargs],XmNmappedWhenManaged,TRUE); nargs++; XtSetValues(form,args,nargs); for (i=0; i<5; i++) { nargs = 0; item_label = XmStringCreateLtoR(labels[i],XmSTRING_DEFAULT_CHARSET); XtSetArg(args[nargs],XmNlabelString,item_label); nargs++; label_widget[i] = XmCreateLabel(rowcol1,labels[i],args,nargs); } XtManageChildren(label_widget, 5); XtManageChild(rowcol1); nargs = 0; XtSetArg(args[nargs],XmNtopAttachment,XmATTACH_WIDGET); nargs++; XtSetArg(args[nargs],XmNtopWidget,rowcol2); nargs++; dismiss = XmCreatePushButton(form,"dismiss",args,nargs); XtAddCallback(dismiss, XmNactivateCallback, popdown, (caddr_t) form); XtManageChild(dismiss); nargs = 0; XtSetArg(args[nargs],XmNtopAttachment,XmATTACH_WIDGET); nargs++; XtSetArg(args[nargs],XmNtopWidget,rowcol2); nargs++; XtSetArg(args[nargs],XmNleftAttachment,XmATTACH_WIDGET); nargs++; XtSetArg(args[nargs],XmNleftWidget,dismiss); nargs++; quit = XmCreatePushButton(form,"quit",args,nargs); XtAddCallback(quit, XmNactivateCallback, killit, NULL); XtManageChild(quit); XtRealizeWidget(root); XtMainLoop(); } ====================Resource Sample 1==================================== !!

My office mate and I are constantly banging >our heads against this wall. Although I don't see any feasible way I wrote my WsMatrixBox widget to do this sort of things (and many, many many more ). You can just say 2 columns, and it will give you ...8 rows, or you can ask for 8 rows and get 2 columns - or you may let the user resize it and get 4x4 layout. I promise I will struggle hard to get permition to make this widget public domain, or some kind of Motif contrib. Yes, it is fully Motif compliant, you may have even 2 column pulldown full of gadgets -). In the menatime, you may try to look at Wcl distribution, which contains Motifized Tab widget, which will most likely do the job as well (I have no experience, using my animal all over the place). But, at any rate.
