I'm managing to generate a PDF with one line-chart from google-chart, but the quality of the generated columns titles doesn't fit our needs, so I want to generate by myself.
This task should be done using [fo:table] but I'm not able to positionate succesfully the titles (widths and margins/paddings).
In sum up, I want to put the titles using [fo:block] setting the width attribute plus a negative margin (i.e. width="1.5cm" margin-top="-2em"), but the width doesn't take effect.
Do you know how to do it?
Thanks.
The "width" property doesn't apply to fo:block (see http://www.w3.org/TR/xsl11/#fo_block). If you want to redefine the width, you need to use an fo:block-container (http://www.w3.org/TR/xsl11/#fo_block-container) or another element that generates a so-called reference area. It's a bit difficult to understand what exactly your expected layout is. Maybe you can also experiment with using "start-indent" and "end-indent" properties to indirectly influence the actual width of an fo:block. HTH
Finally I have not been able to do that, because [fo:inline] tries to gather all the available space.
One trick is to put margins (left or right) to the 90% or more to fill that gap, but I then have no clue the previous [fo:inline] text was rendered in one, two or more lines.
The only way I found to generate the column's titles is using [fo:table] plus adding margins (left & right) to each cell.
PS: I use FOP-0.95
For FOP you may use tables to set width instead of applying it directly on block.

I recently asked this question: Horizontally-Drawn RowColumn Class for Motif Library (C)?
In my previous question, I was having trouble getting the xmRowColumnWidgetClass to draw horizontally (row-by-row) instead of vertically (column-by-column). After playing around with it, figured out how to switch to horizontal drawing with the following snippet:
XmNorientation, XmHORIZONTAL,
So the code that creates the xmRowColumnWidgetClass instance now looks like this:
rowColumn = XtVaCreateManagedWidget("rowcolumn",
xmRowColumnWidgetClass,
parentWidget,
XmNnumColumns, 3,
XmNorientation, XmHORIZONTAL,
XmNpacking, XmPACK_COLUMN,
XmNspacing, 6,
NULL);
However, my new problem is that for some reason the XmNnumColumns field is now referring to the number of rows, rather than the actual number of columns. Before adding the XmNorientation, XmHORIZONTAL part, the xmRowColumnWidgetClass instance was drawing the objects from left-to-right but it stayed to 3 columns like it was supposed to. Now, it is staying to 3 rows, occasionally creating a horizontal scrollbar which I do not want. I only want vertical scrolling.
So I need the children of the xmRowColumnWidgetClass instance to be drawn horizontally from top to bottom, but I need it to only put a maximum of 3 per row and thus keep it confined within a certain width.
I tried playing around with the XmNnumColumns field, but things that worked with more children did not work for less children, and vice versa. Sometimes it made it 4 or 5 columns rather than 3, and sometimes it made it 2 columns with the 3rd column completely empty. I encountered many issues like this even when experimenting with things like using XmNpacking, XmPACK_TIGHT rather than XmNpacking, XmPACK_COLUMN and other stuff.
If someone is able to find the official documentation of the xmRowColumnWidgetClass and link it, that would be be greatly appreciated.
To anybody familiar with this library:
How do I create a xmRowColumnWidgetClass instance that draws horizontally (row-by-row) while keeping it to a certain number of columns?
It should be able to handle any number of children and add as many rows as it needs to in order to keep it as exactly 3 columns.
Another group of examples of this library:

XmRowColumn was designed to implement the top menubar and all the other menu classes... You are searching for a grid like widget, and so you have to use XmForm read the related question for that.
In short: try the WtTable widget
Longer explanation follows:
The behaviour of XmRowColumn regarding "columns" becoming "rows" when you choose a horizontal configuration is very unfortunate. The alternative of using XmForm instead of XmRowColumn for this purpose is feasible, but however it requires manually setting the children constraints, and even then, it's quite possible that you won't be able to achieve the automatic sizing implemented in XmRowColumn.
By searching today, I found the WtTable widget and it works fine for my purposes. It's "almost" as automatic as XmRowColumn and it doesn't require to set any constraints manually. I tried it in my Motif code, and works fine.
Note however that I said "almost" as automatic. The "almost" is because you need to specify the number of columns and rows, and you need to specify the column and row for each child widget. However, all of this can be automated: you can create a convenience function that internally manages counters for columns and rows, so that you pass a widget to such function and it puts it in the cell it belongs automatically: you can even make that function create a new row in the WtTable when it's needed.
The answers in topics with similar titles haven't given me much of a resolution to my particular problem, but possibly I am not asking the right question. It might help knowing I'm an absolute noob when it comes to spreadsheets, so finding my way around is next to nil.
Currently I can set a basic function in the first cell A1 =ROW()
Simple right? Well now here comes the complication. If I click on the bottom right of the cell and start dragging I can then apply that very same function to a whole range of cells. Let's say I apply it from A1:A10. Every cell within this group now has the same function.
Hooray! We did it, right? I applied a function to a range of cells each with their own output. But wait, if I then go back to the original cell and change its formula none of the other cells change with it. GRRRRR!!!!
There are a couple of fixes I've come up with but don't necessarily know how to implement. The first is to have every cell link back to the original cell and reference its function. This would be useful if I wanted to randomly scatter dependent cells about the document. The other would be much more useful in an orderly group where you know the exact dimensions by specifying in the original cell the size of the array you want to apply the function to.
With that said, let me hear your thoughts.
The closest I've come to an answer is to use FORMULA() which returns the formula used by a cell as text. Unfortunately all answers on evaluating the text resort to scripting. How strange! I thought something like this would be common. Might as well get to scripting.
Hold on, I may have spoke too soon. An array can be made with =MUNIT(), but it's only square. Drats!
Ok... I'm hoping the zebra stripes will eventually become its own answer unless someone else beats me to it. So a simple array can be made with ={1,2;3,4} where commas separate values by column and semicolons for values by row except to generate it you have to press Control+Shift+Enter (because reasons?). I'm thinking now that I'll need to have functions that can generate lists of values based on a single function for each row, and pray that it'll work. So, back to looking. (Wow this is taking forever)
The way I was hypothesizing can't even generate a 1x1, e.g., ={ROW()} returns Err:512 which is a formula overflow.
Alright, in summary so far I've narrowed down the two options,
1) link every cell to the original formula
2) populate an array with a single formula
each with their own incomplete answer,
a) use FORMULA() to return the formula of a cell as text
b) create a hypothetical array like so ={LIST_OF_VALUES()}
These both require a strange form of the nonexistent EVALUATE() function to 'function' correctly. Isn't that fun?
Google Sheets handles case b by allowing ={ROW()}Control+Shift+Enter to generate =ArrayFormula({ROW()}). Working with the general case of any sized array being filled with a single function doesn't exist in the world of spreadsheets it seems. That's very saddening because I can't think of a much better tool for what I want to do. Copy paste it is until I need to use macros.
Depending on your specific use case, creating a user-defined function may help:
use the Basic IDE to create your function;
apply it to any cells on any sheet;
modifying the Basic code will affect all cells where the function is used.
I've elaborated the steps in an answer on superuser.
Sure, you could write some complex code to update functions, but wouldn't the easy way be just to drag it to the same range of cells the same way you did before? It should properly overwrite the existing code in there, and if it doesn't, you can just as easily delete the outdated code and drag the new code in.
Probably the best approach is to simply drag the amended formula over the range of cells (as advised by OldBunny2800). This is less error prone and easier to maintain than a custom macro.
Another option would be to use an array function. Then you only have to edit the function once, and the same edit will be automatically applied to the whole range of cells in that array function.
How I can put a a GtkSwitch in a cell (column) of GtkTreeView?
This is possible?
Not really, no. You can only put GtkCellRenderers in GtkTreeView columns. To get something like it, you'd have to implement a custom GtkCellRenderer, which would be very very difficult, and it might be impossible to get the exact same behaviour. GtkCellRendererToggle will give you a check box instead though.
Here are the available standard cell renderers:
https://developer.gnome.org/gtk3/stable/GtkCellRenderer.html#GtkCellRenderer.object-hierarchy
I've got a GtkHBox with 2 items. Inside that, on the left, I have a GtkHBox with 4 items. The first two are GtkEventBox's, followed by a GtkHScale and finally a GtkLabel.
The two GtkEventBox's each contain a GtkVBox with two items, an image and a label (using the GtkEventBox so that I can catch click events on the image). Unfortunately, I can't seem to figure out how to set the width for them. Currently, it looks like this:
But I want the Select and Pan sections to be much narrower. Any suggestions?
Make sure to pack the event boxes into your GtkHBox with the expand and fill parameters set to false.
I am trying to simulate a piece of hardware, and this hardware has a static ribbon display.
to do this, I'd like to use a TextView. My display has 10 rows, with 25 columns. So I figured that a TextView should be easy enough.
basically, I would like to be able to say "insert/replace string S at row X, starting at column Y". i may need to only update a specific row, or even a single column within a row.
I have not been successful at getting this to work though. the best I have been able to do is to fill the TextView with 10 lines of 25 spaces when i create it, and then use the get_iter_at_line_offset to get the iterator of a line, and then push the new text onto that line.
but this will start appending text to the line, rather than replacing the existing one.
I need both row and column control (i.e. need to be able to set text at a specific (X,Y) coordinate).
I'm assuming this is somehow possible using marks.
Can anyone give me a quick example of how i can do this? Unfortunately, there isn't a whole lot of documentation on this sort of thing.
You'll have to get an iter at a specific line, row X, and then use the iterator's forward_chars() method to move forward Y characters. Then delete the number of characters you are replacing, and finally insert the text you want to insert. You can do it all with iterators, I think - iterators are invalidated when you change the buffer, but when you delete text, one of your iterators is revalidated to point to the place where the text was.
If you're targetting GTK+ 3.x, you should really look into using Cairo. Since you don't actually need a text buffer, it seems like overkill and a bit of a mis-alignment to use the GtkTextView.
Look at the very basic introduction on how to draw with Cairo in GTK+. Then look at the text-rendering Cairo APIs, that should be enough to get you started.
