We would want the users to be able to optionally customize our QT applications. So if they would want to create their own theme for our applications, all they have to do is load their own CSS file.
Do we really need to create a plugin to be able to do that? If yes, could somebody give me the basic steps/ or a jump start on how to do it? If no, are there features in QT that I need to know to be able to do that without creating a plugin?
I have a Jabber instant messenger which is plugin based and written in Qt. It includes a style plugin that does exactly what you describe. The source for that plugin is here:
https://github.com/sje397/saje/tree/master/plugins/styles/
(Note: this is a plugin for my application - not a 'Qt style plugin')
Basically all you need to do is load a style sheet and call QApplication::setStyleSheet:
QFile f("filename");
if(f.open(QIODevice::ReadOnly)) {
qApp->setStyleSheet(f.readAll());
}
An example of a valid style sheet is here. Note that it is for my app, so includes some of my own class names etc.

I inherited an already built Drupal 7 site. I have been able to figure out many things. But I am unclear on the CSS. A found a folder full of long-named CSS files but the code is all minified and hard to read. The previous developer had to be using some tools or services to alter and change the code in a more readable way. Does any know what the deal is ?
Also, I cant seem to find any way inside Drupal to enter CSS. I do not even see any classes or ID assigned to the blocks, views, nodes, or fields. So I have no clue how they were able to customize this site at all even though they obviously did. It uses Bootstrap 3 as a theme. Can anyone help explain how this works?
I will try to figure out the essence of the informations you given.
First: You have a Drupal 7 installation with compressed css files based on Bootstrap. That sounds the theme use less or sass precompiler for the theme css and you have the production (builded) instance of the project. Without the uncompressed less/sass/scss files it will be hard to edit the css. if you have no way to get the source files, the best way you can try is to add a extra css file and write you own css in it.
Second: Drupal strictly separates the code from the administration interface. Your PHP, HTML, CSS and other codes (except the WYSIWYG output) should not be entered via the administration interface. That's the best practice way. But anyway, there is a couple of modules that allows to write code inside the Drupal backend like this https://www.drupal.org/project/extra_css_js
Third: As information for you, Drupal 7s End of life is on November 28, 2022 so the best and recommanded way for you is: Freeze the Drupal 7s Instance as is (only Sercurity Updates and Hotfixes) and relaunch the Project with Drupal 9.
Drupal theme css files are mostly located in theme folder like "theme folder/css/style.css". As above mentioned, it might be used css minify tool or module for theme performance aspects. If it is created by drupal tools/module then once cache clear it will delete automatically and regenerate with new one with updated new css code on after page visit. You can also add custom css file by hook alter.
I have setup a QnA Bot via the Azue BotService, and I want to use the WebChat channel, but the default MS Design for the chat interface is quite bland; is there a way for me to edit it?
Is it possible to go form the default theme on the left, so something like Air New Zealand's bot on the right in the image below?
It depends on how you want to integrate the webchat in your page but yes it is possible to change the aspect, it's only css and js
All the details are provided on the GitHub account for the Webchat: https://github.com/Microsoft/BotFramework-WebChat
In a few words:
Want to run a custom build of WebChat? Clone this repo, alter it, build it, and reference your built botchat.css and botchat.js files.
And for Styling:
Styling
In the /src/scss/ folder you will find the source files for generating
/botchat.css. Run npm run build-css to compile once you've made your
changes. For basic branding, change colors.scss to match your color
scheme. For advanced styling, change botchat.scss.
I'm new to QT and I'm trying to see if it's possible to load an external stylesheet from a global stylesheet just like in web dev, something like using the syntax "link rel="stylesheet".
Right now we have a global CSS sheet that is being called via C++ code with all the global elements and specific widget modifications, it has 2k lines of code and it's becoming unmanageable. I know I can keep the global file and start adding resource stylesheets or pure code put directly into QT Creator Style Sheet editor for each widget. However, the head of development really wants to separate that my code from his team, so avoid any changes in QT UI file as much as possible, so if something breaks he will know when it was me or him.
Is this possible? can I call a stylesheet from a stylesheet? I couldn't find this syntax in the QT guide.
My goal is to have more themes for my application and if possible, bundle them with the application itself, not load them at runtime using IStyleManager.loadStyleDeclarations().
Using the theme command-line option, you can have more than one "compile-time theme" bundled with your application according to docs:
theme filename [...] Specifies a list of theme files to use with this application. Theme files can be SWC files with CSS files inside them or CSS files.
However, I wasn't able to find an example how to actually do that (use the += syntax on command line?) and switch between those themes at runtime. What API should I use?
Using the theme command-line option, you can have more than one
"compile-time theme" bundled with your application according to docs:
Yes, You can add additional themes using the += in your command line.
I do exactly this for the Flextras mobile demos; including both the generic Spark theme with the Mobile theme to create the app.
However, both themes will be attempted to be used. I believe the second takes precedence. That means for every class where you want to use the "other theme" you have to specify that theme be used manually. This could get pretty complex very quickly; and you'll have to re-create a lot of spark skins in your application. I've done some work for a client around this who wanted to use our mobile DropDownList in both their normal application and in a mobile application from the same code base. I think the appropriate skin is conditionally applied at runtime using CSS; however we had to create a skin for the "non-mobile use" that explicitly specified the non-mobile skins for the individual elements (Such as the scroll bars)
i have create a customize feature in open atrium. now i have to implement the a javascript file like mindmap in that customise feature. how can this possible to add in the open atrium feature.
i have completed the feature using the book module of the open atrium. Now i have to change only the text area in to mindmap.how can it implemented in the feature.plz help me.
You are using the open atrium custom feature and want add a js file then you can follow the build a feature link https://community.openatrium.com/documentation-en/node/449
and then read the drupal_add_js function in the link http://drupal.org/node/304255.
You want to use drupal_add_js() in a custom module or theme depending on what you are making. If it is a one off site just add it to your theme. If youre trying to fix the moduel add it directly to the upstream module. If youre augmenting the module for your own purposes add it to a new helper module so that you can upgrade that module in the future without concerns of losig your work.
