Attach position to 33% of the form width.

I have to ask a dumb question but how, exactly, do I specify this in UIL
attributes?

I concurr, I would also very much like to know how % of form width can be
specified in a UIL.

The answer is to specify the attachment as XmATTACH_POSITION and the use
XmNxxxPosition attribute with a value.

Below is the mmodified UIL. As you can see, ABSTagButton has a right
attachement at 33, ABSCommentsButton has a left attachment to the widget and
a right attachment at 66, and ABSTradeButton simple does a left attachment to
the widget and a right attachment to the form.

object ABSTagTradeForm : XmForm {
controls{
XmPushButton ABSTagButton;
XmPushButton ABSCommentsButton;
XmPushButton ABSTradeButton;
};
arguments {
};
};

object ABSTagButton: XmPushButton {
arguments {
XmNtopAttachment = XmATTACH_FORM;
XmNbottomAttachment = XmATTACH_FORM;
XmNleftAttachment = XmATTACH_FORM;
XmNrightAttachment = XmATTACH_POSITION;
XmNrightPosition = 33;
XmNlabelString = "Tags...";
};
callbacks {
XmNactivateCallback = procedure manageTransientWindowCB("Tag Dialog");
};
};

object ABSCommentsButton: XmPushButton {
arguments {
XmNtopAttachment = XmATTACH_FORM;
XmNbottomAttachment = XmATTACH_FORM;
XmNleftAttachment = XmATTACH_WIDGET;
XmNleftWidget = ABSTagButton;
XmNrightAttachment = XmATTACH_POSITION;
XmNrightPosition = 66;
XmNlabelString = 'Comments...';
};
callbacks {
MrmNcreateCallback = procedure bindCB("AttributesButton");
XmNactivateCallback = procedure manageTransientWindowCB("Attributes");
};
};

object ABSTradeButton: XmPushButton {
arguments {
XmNtopAttachment = XmATTACH_FORM;
XmNbottomAttachment = XmATTACH_FORM;
XmNleftAttachment = XmATTACH_WIDGET;
XmNleftWidget = ABSCommentsButton;
XmNrightAttachment = XmATTACH_FORM;
XmNlabelString = 'Trade...';
};
callbacks {
MrmNcreateCallback = procedure bindCB("TradeEntryButton");
XmNactivateCallback = procedure manageTransientWindowCB("TradeEntry");
};
};

Make sure you also set the XmNfractionBase resource of the form to 100.
This is the default, but if the user has a setting in some XDefaults
file that alters that, she will get strange results. For example, if she
has:
?*fractionBase: 200
your buttons will be scrunched up in the left half of the form.
If she has:
?*fractionBase: 50
bad things will happen.

What is the magic trick to tell the UIL compiler that the value "33" is a
percentage versus an absolute position in pixels ?

Hmmmm. Don't you use the XmNxxOffset to specify absolute pixel postioning?
XmATTACH_POSITION, then, is always percentages. At least I _think_ that's
how it works?

Thanks. I stand corrected. I had looked some time ago and had concluded it was
not possible to do relative positioning (percentage of width), but in the end,
I had *assumed* POSITION was absolute position whereas "offset" was offset
from the gizmo to which the widget was being positioned against.

This is great. I had been looking for such functionality and there it was
right in front of me and I couldn't read it :-)
