I would like to embed another widget in one end of a GTK+ 3 text entry box, a bit like many browsers do with search or protocol security "chips":
I know I can set an icon on a text entry with
entry = Gtk.Entry()
entry.set_icon_from_icon_name(Gtk.EntryIconPosition.PRIMARY, icon_name)
Even if I pass my own GdkPixbuf to set_icon_from_pixbuf this still limits me to icon sizes, when I want some arbitrary size (at least horizontally) depending on the "chip" content.
I also tried to "shunt" the text over with set_margin_left, but this moved the left edge of the whole entry box over, rather than the text within the box.
What would be an effective way to embed some other GTK+ widget (hopefully of any complexity, so I can make the chip more interactive) within a text entry?
GtkEntry is not a container, so it cannot have child widgets.
The appropriate way to implement what you see in the screenshot is to use a separate container and style it appropriately.
Have you considered putting the entry inside a frame, and restyling stuff to make it look like it was inside an entry? Then you could use standard containers to put whatever widgets next to the text entry spaces that you wanted.
The downside is that clicking your "icon" doesn't focus the entry automatically, but it makes that action totally configurable.

I am starting to make my Vaadin web app responsive. Reading Vaadin docs, I managed to make a CssLayout flexible such that an image is shown either to the left of a text section or in a separate row depending on available width.
Now I want to make my login form flexible. By default, captions are moved to the left of the fields. How can I achieve that the captions are moved to the top of the fields when a certain width is reached? Is that even possible with FormLayout?
Can't really imagine that it is possible with CSS because the FormLayout is rendered as HTML table. If so, what is a simple alternative?
That is not possible with FormLayout. Structure of FormLayout is not flexible. Also there is not simple alternative for that. You can use CssLayout or create your own component container.
Starting point for this can be extending AbstractComponentContainer as described in Creating a simple component container
I'd like to create a layout to show this table in list view, the point is to make the text field resizable according to content. I have try several method, but all fails. I am using FileMaker 12.
Any help much appreciated.
For Browse mode you can set layout objects to dynamically resize based on the layout size, but not on the object contents. If you need this functionality in Browse mode you will probably need to use a web-viewer.
In Preview mode you can use sliding left and sliding up for reduction of the size of the layout objects, but there is no option to expand.
In Browse and Find modes, if a field isn't set to have a scroll bar, the field will expand while the user is entering data, but only then. It will return to the default size when the user navigates to another field or another record.
In Preview mode, you can make the field larger than it could possibly need and set it to slide up and also reduce the size of the enclosing part. But the user won't be able to interact with the interface of the layout (can't click buttons, change data, etc.).
A workaround might be to use a tooltip. If you set the tooltip to the contents of the field itself, then the user can hover over the field to see any expanded contents.
If you really need exactly the functionality that you mention (which I would define as having field height and enclosing body part expand in list view based on the field's content length while in FileMaker), the only way I could see doing it would be to use custom web publishing to create a web page and use FileMaker's web viewer to show that web page. F 'n' web has an article that might be of some assistance if you go this route.
Is there a text editor which offers horizontal, rather than vertical, scrolling (showing two pages side by side)?
I currently use TextMate, but would switch to any editor which offers this layout. I'm getting really bored of scrolling up and down, over and over.
I've attached a screenshot of MS Word, which has a side-by-side horizontal scroll view for documents longer than a page.
I want something like that, Any recommendations?
Emacs offers a follow-mode which you might find helpful ( see for instance here http://www.emacswiki.org/emacs/FollowMode).
A short description of how it is used and what it does:
You need to open a buffer in two windows and enter follow-mode using M-x follow-mode. This is actually a bit of a drawback, because you need to learn how to use emacs, if you don't know it already (imho learning how to use emacs is worth spending some time).
After entering follow-mode the second buffer will skip to the place where the first buffer ends, similar to the page-by-page view offered by Microsoft Word. Now if you move the cursor down one line at a time and you leave the first buffer window at the bottom, the cursor will appear at the top of the second. If you move further down and you are at the bottom of the second window, both buffers will scroll simultaneously, the same holds for page-wise scrolling using C-v and M-v.
If your monitor screen is wide enough, you can open a third window to further increase number of lines being displayed.
I have made a screenshot, which shows a text file opened in this mode: Screenshot auf Follow mode
Hmmm, it seems you are looking for layout features which you aren't likely to find in a text editor. Text editors are generally line based and don't understand the concept of pages. Text editors do things like code folding and allow lines to be wrapped or not. That is why text editors scroll in the vertical direction. These factors would affect pagination.
The concept of a page (and being able to lay them out side by side) doesn't really exist unless you are using a presentation manager such as a word processor or a desktop publishing package.
In vim: <Esc>:vsplit will open a second column for the file.
In all fairness, I should warn you that Vim has a steep learning curve, and will force you to wrap your head around new concepts like command mode / edit mode / visual mode. The results are definitely worth it, if you have the time to learn it.
I'm not sure if I know exactly what you want. Does Sublime Text 2's two-column layout with File > New View Into File do what you want?
A change on one side is reflected instantly in the other side, and you can scroll them independently. You can have up to four columns per window.
In LibreOffice Writer, go to View -> Zoom... and set Zoom factor to Fit width and height, and set View layout to Automatic. You can also set the number of columns manually, and if you choose two columns, you can use Book Mode.
With scroll-binding in vim, you can edit two files side by side: scroll-binding in Vim.

I would like to add an icon to the header of my data grid as it is done in Thunderbird.
There is an icon that is above the vertical scrollbar, no matter the position of the horizontal scrollbar. This icon allows the setup of the columns.
In Delphi there a lot of different grid components, that allow customizations and adding icons to there cells / header cells. But I could not find any component that has an area above the vertical scrollbar that is fixed, which when clicked allows some action. I could even use the VirtualTreeView component to emulate the grid, if it turns out to be easier to customize that component.
I am looking for some guidance on what need to be done to get that functionality.
Thanks,
Thomas
VirtualTreeView in Listbox mode would be nice, because of it's speed, great documentation and ease use in MVC-like patterns. Delphi tempts to store data in the visual components themselves, which letter causes troubles. While VTW allwos the same, it also allows to acutally separate data from GUI, and i like it.
But i am surprised by your claim "which when clicked allows some action.".
Even most basic components allow it:
http://docwiki.embarcadero.com/Libraries/XE2/en/Vcl.Grids.TCustomGrid.OnFixedCellClick
So could you make more detaiils, why you cannot use standard components ? with screenshot and editors, how u want it rendered, where you want to click and what kind of action should happen ?
I am trying to display items retrieved from an XML DB using xforms:select1 control using appearance=xxforms:tree. The items appear collapsed or expanded automatically and the behaviour is not the same for all the items retrieved. I have the following questions regarding xxforms:tree view:
how to make sure this view shows sub-nodes (those expandable/collapsable using +/- icon) as collapsed or expanded always, irrespective of, for example, the no. of nodes covered by the + icon?
how to render select1 with tree appearance without making any of the items hyperlinks?
how to make sure no item is highlighted/selected by default?
...and although the docs say xxforms:menu is also a possible appearance (URL http://www.orbeon.com/orbeon/doc/reference-xforms-extensions#tree), the details are not available...
About which branches of the tree should be open — By default all the nodes leading to selected nodes are open, this so the selected values are all visible. But you can change this default behavior and specify which nodes should be open using the xxforms:open attribute. For more on this, see the section "Controlling which tree nodes are initially open" on Selection Controls. Note that this feature was added in October 2010, so it is not included in Orbeon Forms 3.8, and until Orbeon Forms 3.9 is released, you'll need to get a nightly build for this.
About using links in the tree — At this point, the nodes you can click on in the select1 appearance="xxforms:tree control are rendered as links, so users know that this is something they can click on to make a selection. I assume that you don't want them to show as links because the tree might be "read-only" in your case (for information only, not to make a selection). This isn' supported at this point. As a workaround, you could use CSS to change the pointer and appearance of links in the tree so to users they don't even notice that this those are links.
About the menu appearance — It works very much like the tree appearance. See for instance this example using the menu.
