I would like to add vertical blank space between two lines in a Modelica component GUI. I have (in this case), six similar looking parameters/comments within a group on a tab that I would like to visually break into two plus four by using a little space after the second one (essentially a blank line, but ideally I would have some control over the gap space).
I can put the last four in a separate group with no name, which gives a line in between the two/four. This is better than nothing, but not really what I want. I tried using groupImage, but it locates the image relative to whole group, so if it's smaller than the six entries, it doesn't affect them at all; and if it's larger, it introduces uniform spacing between all the entries, rather than just between 2/3.

I'm working with CR version 13.0.25 - I believe the actual latest version as of this date is 13.0.26, so, basically the latest version of CR. What I am working with is re-positioning elements on the report dynamically from the C# code.
There are a couple of the reports where the original rpt (designed a number of years ago) spans multiple pages. These in particular are giving me issues, but they are not the only ones. The issue here focuses on the y (vertical) dimension.
CR documents use a coordinate system that is based in the upper left corner of the document, and is also based on twips (1440 twips/in). So, in theory, I should be able to set the Top value for a ReportObject to 1440 and that element should be printed 1" from some benchmark (either top of the page or bottom of the margin - I'm fairly sure it's bottom of the margin).
My results do not seem to reflect this - at least not exactly.
When I set the Top value, it appears that with some of the documents, the y dimension is scaled. In fact, I can apply a constant scaling factor (it varies according to the document) and I can make the fields appear with a relative 1" spacing all of the way to the bottom of the page. However, that scaling factor varies from document to document.
So, besides experimenting in our production code, I have also done the following:
I created a C# console app that opens an rpt file, grabs some of the elements on it, and re-positions them, then sends it to the printer. I designed a new rpt file with headers and footers sized as small as I could get them, and put 10 text fields in the details section. I iterate through the fields (via ReportDocument and ReportObjects and re-position them at 0, 1440 (1"), 2880 (2") etc.
This works perfectly with a document that has the default margins (.167 inches by default on each side). The first element has its top butted against the bottom of the margin, the second element is 1" from the top of the first element to the top of the second element, and so on down the page. If, however, I reduce the margins to zero - either programmatically or in the design, I get this scaling effect. The elements are all now about 7/8" or so apart, instead of the 1" that I would expect.
Does anyone know of any magic formula(s) or documentation on why the coordinate system appears to be changing? I could understand that if I change the margin that could offset everything on the page (assuming that the margin is our baseline) but it would seem to me that the inter-element spacing, being 1440 should still render at 1".
I believe Y is the vertical distance from the top of that section, not from the top of the page.
I would like to have a text box rescale with the level of magnification, such that one unit of text is always assigned one unit of horizontal axis-length. The text width should not change but rather the spacing between characters.
For instance, if the x-axis displayed [0:50], fifty characters should be displayed, one at each integer position. If the magnification was increased such that the display comprised only [0:10], only ten characters would be displayed, again placing one character at each integer position along the horizontal axis.
Finally, the text would ideally not display when the magnification level was below some threshold determined by the number of characters that can be legibly printed along a horizontal line spanning the extent of the axes.
I have tried using the text object, but it doesn't seem to have the relevant properties to allow such dynamic behavior. I have instead considered breaking the N-length string into N unit-length strings and placing each at a defined x-position, but I'm having trouble figuring out how to display only those relevant at the prevailing zoom level (there is some spill-over of characters beyond the bounds of the axis). In contrast, with this approach, all the characters appear as a jumble at zoom levels so low that the number of characters printed cannot be reasonably accommodated.
Thus, I inquire whether another solution besides printing a series of unit-length strings might be advised and, if not, how the twin problems of text spill-over and text overlap can be resolved at high and low zoom, respectively (the first might be done by somehow preventing printing of information outside the axes; the second seems to require some dynamic magnification-aware means of suppressing text output at or above a certain x-axis extent).
I am using a table to create a semblance of what is depicted below. The content I'm generating isn't known before hand. The blue sections of the columns are cells that are kept together in the table and I am using ColumnText to display the table. For clarification I have outlined a sample cell layout in the top right of the image. The problem I'm running into is that when I use setSplitLate(false) with setSplitRows(true) alongside with using keepRowsTogether(int[] rows) the splitting doesn't work correctly. Most of the top right section should be able to fit into the bottom left but as shown in the image it is all moved to the top of the next column.
Is there a way to cause the cell to split as well as keep together with it's header? When I remove the keepRowsTogether(int[] rows) call the cell splitting works as expected.
Also, in my situation I only want it to split if there are two lines at the end of the column and two at the beginning of the next. In other words the cell would only split if it contained 4 lines of text. How would I go about doing this?
I modified the top right column as depicted below, blue representing the rows that are kept together.
As depicted, I have a cell for the header as before but I've split up the paragraph into many different cells. The first and last contain cells with two lines of text and the rest contain one line of text. This way I'm guaranteed that the header will stick with at least the first two lines of the bulleted paragraph. If the last two lines, or the last cell, end up not fitting in the column then because the cell contains two lines, I'm guaranteed that at least two lines will be carried over to the next column, if not more, depending on how many of the middle lines carry over as well.
I have several items that I want to line up. The Width and Height of all fields match. Usually I just use the Align, but it's making it worse. My out of line field which is slighly lower, moves way up, way out of line (with align tops)
So I tried using the Size and Position to set it manually. Several objects have a Y of 0.056, but my last one has 0.061. I change the last one to 0.056 and save it. It doesn't appear to be different, and when I look at it again, it's still 0.061. (When I used align, it went up to 0.028!)
I do NOT have Snap to Grid set (my grid size is 0.083). (Nor does turning on Snap to Grid make them align.) The fields have exactly the same formatting. But unless I can magically make them align by hand, they refuse to align. Why?
You've already done a lot of the regular troubleshooting steps. One more ting that I sometimes do is to select all the fields I want to align, then use the arrow keys and move them up into the section above and then back down into their original section. That usually puts them all into the 0 position. If it dosn't work with all of them selected, try each one separately.
The way I understand how emacs displays stuff is that essentially everything is text. If you have something in the fringe or linum mode active, essentially your document is pushed a little inwards and something is written in the first few columns.
I'm writing a function for putting some stuff into the head-line and this works nicely, however, I would like the start of the text to be aligned with the start of the document.
Thus I am looking for a way to get the number of columns that sit between the frame border and the start of the actual document.
Let me illustrate using a poorly produced graphic:
I want to get the number of columns (or the number of pixels) that make up the distance marker by the ruler just below the line number 10000.
The function which returns this value shall be executed in the functions which create the head-line.
There is a function called window-inside-edges that you can use to determine the offset of the text area ("window body") from the total width and height of the window in columns and lines, respectively.
It returns a list four values; the order is left - top - right - bottom, so to get the value you are interested in for the current window, just do
(car (window-inside-edges))
More information on window coordinates can be found here; this page has information about window sizes, including a nice ASCII representation of window elements.
