In my code I have widgets and change their styles the following way:
resultGroupBox->setStyleSheet("background-color:#7979ec;");
And later in code:
resultGroupBox->setStyleSheet("font: bold 14px\"Verdana\"");//this is done by function (set_fonts());
After the second style is applied the first is lost. I wonder if there is a way to deal with this (I need the both the fonts and the background), except for setting background-color and fonts in the same command.
It looks like your function is "setStyleSheet", isn't there a function to "AddStyle"?
Even better is adding a class instead of a style. For example with the jQuery addClass function. See https://api.jquery.com/addclass/

Some background: I've converted my designer's Sketch text styles to classes in a css module. For this example, I have a "labels.module.css" file, containing the styles for each type of label in a class name. Here is an excerpt (the #apply comes from tailwind):
.labelNormalLight,
.labelNormalMidGray,
.labelNormal,
.labelNormalWhite
{
#apply font-normal font-sans text-xs leading-3;
}
.labelNormalLight {
#apply text-neutralMediumLight;
}
Now I have an element that I'm using the style .labelNormal on. However, when that element's parent is hovered over, I need to switch the styles to that of .labelNormalLight. For this, I wrote another .module.css file, and attempted to compose the two styles inside it:
.name {
composes: labelNormal from '../styles/labels.module.css';
}
.person:hover .name {
composes: labelNormalLight from '../styles/labels.module.css';
}
This however fails, as CSS Modules do not allow composing except within single local class names, per this error:
Error: composition is only allowed when selector is single :local class name not in ":local(.person):hover :local(.name)"
So my question is: How do I achieve keeping my CSS DRY, but also allow me to override styles based on parent states? I've thought about exporting the values, but then I have to know what values to override.
Update:
So I was able to accomplish this using using Sass's #extend, by specifying %labelNormalLight and extending that. I wasn't able to achieve this with tailwind however, due to me being unable to get tailwind working in Sass. I'd still like to know how to do this without sass though, as it's literally the only reason I'd need it.

I'm having an issue with colors in span text that are controlled by Pango.
Long Version:
I'm updating an old UI program which has C++ code guts with GTK, XML (written by Glade), and an RC stylesheet handling the graphics. Some of our colored markup text is hard-coded in the XML. Some of it is dynamically set in the C++ code.
The problem is, that when the program runs on our older systems, the color referenced by span text as 'green' shows up as #00FF00. On our newer systems, 'green' is showing up as #008000.
Example of code printing to a label widget:
gtk_label_set_markup((GtkLabel *) TitleBarLabel, "<span color='green'>Orbital Cannon Positioning</span>");
I'm fairly certain that Pango is in control of the span text markup. I found that the difference between the greens is exactly the difference between X11 and W3C color lists (https://en.wikipedia.org/wiki/X11_color_names#Clashes_between_web_and_X11_colors).
It seems that our old systems are using X11 and our new ones are using W3C, which makes sense.
I could just replace all instances of 'green' with '#00FF00' but if we wanted to change the colors in the future, we'd have to go through the whole thing again. I'd much rather have the colors changeable through a stylesheet instead of baked into the code.
C++ Code:
GtkWidget * TitleBarLabel;
TitleBarLabel = GTK_WIDGET (get_builder_object (builder, "TitleBarLabel"));
gtk_label_set_markup((GtkLabel *) TitleBarLabel, "<span color='#00FF00'>Death Ray Power Status</span>");
I can create a GdkColor at run-time and gdk_color_parse it with values from a config file, and then use gtk_widget_modify_text() to apply the color to the label widgets. But then that doesn't work for all of the hard-coded span text in the XML. Also, we have pleanty of labels with bits of text colored differently inside the same line.
C++ Code:
GdkColor pass_color;
gdk_color_parse("#00FF00", &pass_color);
gtk_widget_modify_text(TitleBarLabel, GTK_STATE_NORMAL, &pass_color);
I can make a style in my RC file for each color and link every single label that would use that color at run-time. But we'd have to remove all markup coloring and add lots of code for grabbing widgets that we never bothered with before and code for setting names of widgets instead of just printing to them with new span text. It gets the desired result of having the colors changeable in a stylesheet but it's a massive undertaking and it's not intuitive for our veteran engineers who are used to using the color attributes.
RC File:
style "pass_color"
{
fg[NORMAL] = #00FF00
}
widget "*TitleBarLabel_Pass" style "pass_color"
C++ Code:
gtk_widget_set_name(TitleBarLabel, "TitleBarLabel_Pass");
Short Version:
Ideally, I would like to be able to make a new color at run-time that we can link with span text in such faction:
<span color='MyNewColor'>Weather Manipulation Settings</span>
Or maybe even create a new tag that applies specific attributes, like:
<span><MyNewColor>Shark Tank pH Balance</MyNewColor></span>
But I doubt that's possible.
I tried playing around with pango_attr_type_register(), pango_attr_foreground_new(), and friends, but I couldn't figure out how attributes work of if they could even do what I thought they did. After much research, it looks like an 'attribute' is just a one-time setting on a single string of text. And not a new value that can be called in line with span text, as I hoped.
Is anything like this remotely possible without rebuilding all of Pango?
Is there a different work around that would get me a stylesheet like setup?
At this point, I'm open to suggestions.
Version Specs:
Computers showing green as #00FF00
OS: Linux Slackware 13.37 and below
GTK: 2.24.4
Pango: 1.28.4
Computers showing green as #008000
OS: Linux Slackware 14.1
GTK: 2.24.20
Pango: 1.34.1
If you are able to use GTK 3.x, I would suggest doing that, where this is much easier to do using CSS. There is even a way to use multiple CSS styles for different regions in the same label, though it is awkward.
In GTK 2, as you noted, you can reference widgets by their name property in your RC file:
widget "shark-tank-ph-label" style "green-text"
style "green-text" {
text[NORMAL] = #008000
}
I would recommend taking this approach even if it's not what you're used to. Refactoring once to remove the hardcoded colors from your labels will make it much easier the next time you have to change something like this, and will also make your code closer to how things would work in GTK 3.x should you decide to make a port in the future.
I have this::
FB::DOM::ElementPtr _element=m_host->getDOMWindow()->getDocument()->getBody()->getElementById("plugin0");
I got the element(i.e. object tag of the plugin that i wanted) by ID. It's compiling. I now want to SET its property from the JSAPI side...like border color style and width....
I went through this page . I could find only 1 method "setInnerHtml"...which sets something. What should i pass in its argument...?it has std::string type...so that I can manipulate the plugin's document. Any ideas...
Basically I want to set the attribute of a tag from PluginAPI side.....
Honestly? You'd be much better off putting the plugin in a div at 100%x100% and then managing the border of the div. For something like this I'd probably just use:
m_host->evaluateJavascript("document.getElementById('pluginCont').style.border = '1px solid black';");
That'll be the easiest. You could also look at the DOM abstraction code and add some tools for managing CSS; note that on IE you may need to use special activex methods to do this, which is why I dont' recommend just doing it through getDOMElement() (which is a shorthand, btw, for the long code you have in your example)
i´m developing a theme and for some reason i need to move the default position for breadcrubms (also for many other things) over woocommerce themes. Then i realised to do something like this on my functions.php:
function woocommerce_remove_breadcrumb(){
remove_action( 'woocommerce_before_main_content', 'woocommerce_breadcrumb', 20);
}
add_action('woocommerce_before_main_content', 'woocommerce_remove_breadcrumb');
function woocommerce_custom_breadcrumb(){
woocommerce_breadcrumb();
}
add_action( 'woo_custom_breadcrumb', 'woocommerce_custom_breadcrumb' );
And then on any template file, output the breadcrumb just with:
<? do_action('woo_custom_breadcrumb'); ?>
And works. My question is more than that. Is this the correct approach for something like this? I mean for anything over woocommerce, not just breadcrumb, for any pice, ratings, titles, buttons, sidebar, and so on.
What i´m thinking on is why woocommerce templates don´t come with more deep code. I mean, why there´s no such a single-content-loop.php template where you can just change the order of things, title, category, content, images, etc. in an easy way rather that hooking into functions?
I think that is an acceptable way to call the breadcrumbs explicitly. Sometimes it is easier to call a specific function than remove everything around it!
As for changing the order of things and getting into advanced customization; there isn't a single file, but a number of files working together. Create a folder in your themes root called 'woocommerce' and copy the following files for a safe override:
woocommerce/woocommerce-hooks.php:
Here are your hooks, including the ones you are overriding in your themes functions.php. Here is where you can experiment with removing and repositioning certain elements on your product page. Search for 'Sidebar' and you will see where the 'woocommerce_sidebar' action is added with the function it references in...
woocommerce/woocommerce-template.php:
Here are the functions used in template files to output content based on conditional statements. For instance, search for the 'Single Product' series and you can see which template files are used for which functions. For instance 'woocommerce_template_single_title' uses 'single-product/title.php' - if you copy over this folder and file you can make very specific edits to just the title section
Between these two files and their accompanying references (like title.php) I believe you can do the things you described. Let me know how it works out! I'm new to woocommerce too!
I have a page template in Tridion 2011 with Razor code that prints information based on RenderComponentPresentation() as the first thing in the page. No other markup comes before it, because the component, not the page, contains the initial markup. Unless I put at least one character before the first RenderComponentPresentation in the published output, the template refuses to render any presentations.
So, for example, if this is all that is in the layout TBB this works (in my real code the tcms are real of course):
<
#RenderComponentPresentation("tcm:mytcm","tcm:myothertcm")
but this does not
#RenderComponentPresentation("tcm:mytcm","tcm:myothertcm")
The first prints the contents of the component preceded by the "<", whereas the second does nothing at all. I don't want to have ANY markup directly at the start of the page template, I want the first thing to be the component. Is it possible?
I've just done a quick test in Template Builder using the latest version of the Razor Mediator (1.2) and couldn't replicate your issue.
Maybe you could try:
<text></text>
#RenderComponentPresentation("tcm:mytcm","tcm"myothertcm")
It won't render any additional markup but may trick the mediator into doing what you want (though like I said, I can't replicate your problem so can't verify whether it does).
Normally with Razor you iterate over any and all Component Presentations on the page, and right now I'm working with
#foreach(var cp in ComponentPresentations){
#cp.RenderComponentPresentation()
}
This will render every component on the page, regardless of predefined schema's or templates. Your issue however suggest a problem elsewhere. What kind of output does your page template generate (do mind its the page template using a compound template which in turn includes the Razor TBB you describe here). Is it .aspx, HTML or other? And what is the Component templates' output? is it an HTML fragment, or anything else?
As far as you syntax goes, that should be just fine other than the template invocation:
#RenderComponentPresentation("tcm:x-xxx-xx", "tcm:xx-xxx-xx")
I have a feeling this code only works when used within HTML tags, though, but that's just a hunch.
Bit of a hack but have you tried:
<text>#RenderComponentPresentation("tcm:x-xxx-xx", "tcm:xx-xxx-xx")</text>
or
#Html.Raw(RenderComponentPresentation("tcm:x-xxx-xx", "tcm:xx-xxx-xx"))
Disclaimer: not really used Razor mediator. Just Razor.
