How can I clearly tell to struts2 to right-to-left arrange components and vice-versa, on runtime, when changing language ?
For example : s:textfield tag makes the label on the left and input on the right. So I would like to inverse this orientation on runtime when switching to a rtl language.
I tried struts2 simple theme, dir and labelposition attributes without any success.
If there is any way to rearrange all struts2 page components in once, it will be welcome.

We faced several limitations when creating form using form builder:
When I drag an UI control into a grid cell, the UI control's label and the UI control itself are top down aligned. How to make both aligned at the same row (side by side). I could only figure out the way to do this by using bootstrap CSS.
When we started to customize the form with CSS more & more due to the form builder limitation, the form designer no longer show the exact form output. This trouble us as we need to test/publish the form to view actual output which defeat the purpose of WYSIWYG editor.
for the time component, is there any option to prefix zero in front of selected hour?
Appreciate anyone can help on this.
Note:
I am using orbeon forms 2016.2 for the form development.
Is it possible to make Sprites position themselves one after another automatically.
Similar to display:display-block in CSS.
For example i'm adding Sprites to some parent in a row, the way they are in xml skin file and they are automatically position themselves next to each other.
Is there an event, which tells that a child were added to the parent?
I could implement some extended Sprite, to position pushed elements automatically, by calculating where the last element is located?
Why the hell Actionscipt doesn't have something like CSS in it? It's a pain in the ass to build UI inside it, compared to HTML...
Madness...
In case of "raw" ActionScript you should either search for an appropriate library or do it your self. ActionScript doesn't define any CSS like logic.
On the other hand Flex does, but you will not find any CSS that let you define layout. CSS is used to modify visual appearance of containers and components in Flex. Layout is usually done with the layout property of the container classes provided by Flex. For example yo can use a Group and set its layout property to an instance of HorizontalLayout or VerticalLayout. This will automatically position all child components of the group either in x or in y direction. In case of using Flex you cannot use sprites directly, but there are many components you can use. Maybe there is one for your purposes.
See the Flex API documentation. The spark.components package will be a good starting point.
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 ?
There seems to be not much information available about this subject so hopefully someone can give some suggestions.
I would like to change color and style of different parts of text in a stringgrid cell.
Example:
20-02-2011 - Document Title
Would it also be possible to show an icon in a stringgrid cell?
It is indeed possible to show icons or bitmaps in a string grid, the Monkey Styler blog includes an example of how to customise cell display in a FMX grid.
http://monkeystyler.com/blog/entry/firemonkey-grid-basics-custom-cells-and-columns
Thinking about the other part of your question though, you will have to build a style up to display text in different fonts, as yet FMX does not have a richtext equivalent or HTML rendering components (I'm sure the latter will come, the former I am not confident on getting for a while!). You would have to have a text component in the style for each different font size/style etc, you would need to name the text elements (using binding or stylename properties) and handle the setting of the text contents using code in the ongetvalue and onsetvalue events (I guess you could also use a onapplystyle event) to display some text in bold and some not.
The event handler would then use either a binding - which is easier to set but - in my experience - buggy;
mycell.binding['boldtext']:='sometext';
Or find a style element by stylename by using findstyleresource;
tempobj:=mycell.findstyleresource('boldtext');
if tempobj is ttext then
ttext(tempobj).text='sometext';
Excuse any bad coding style there, but you get the general idea (I hope) if you set autosize to true for the ttext components in the style and align them left you get - mostly - what you are after. The only issue is that the resulting text doesn't look quite seamless because autosizing and aligning left doesn't really give you the same space between the fonts that you would get with a richtext or HTML display. You should be able to fiddle with the padding (giving it a negative number for the left padding should allow you to remove any extra space) but you have to live with that not being entirely perfect compared to proper font hinting and alignment.
I would like to programmatically set a border around a Form component in Java. How can I do this without having to edit the css style sheet?
You could wrap the form with a Panel component, which has a border defined already. Otherwise, not much alternatives than just using CSS.
One option, if you wish to stay inside the server environment, is to use the CSSInject add-on and add the border using that (you still need to write CSS, but you can do it on the server in a Java file and not inside a regular CSS file).
Vaadin Flow — Style::set to specify CSS
In Vaadin Flow (Vaadin versions 10 and later), you can conveniently set CSS for a widget or layout programmatically. No need to edit separate CSS files, even though styling with CSS files is the recommended way.
On your widget/layout, call getStyle to retrieve the Style object.
On that Style object, call set to pass the name and value of your CSS property.
For example, I find setting a bright colored border on my nested layouts quite helpful for debugging.
myVerticalLayout.getStyle().set( "border" , "6px dotted DarkOrange" ) ;
You can see this in action with this screenshot on my Answer to another Vaadin question here:
