In my project i'm trying to use qt linguist. When i change the language from English to Turkish, it is working all constant label.
But some labels i m loading them dynamically according to scenario of use cases.
Whatever i do with qt linguist, it doest workthe texts of these label.
How can i get rid of this problem?
Any help will be apprecialted
Qt has a guide to internationalization, which includes the basic information: to wrap your string in a tr function call.
label->setText( tr( "Hello, World!" ) );
In addition to this, if you want the language to change on the fly, you'll need to identify when the context has changed, and update your labels appropriately. Unfortunately, I can't easily put my hands on the signal that indicates when to do so.

I have a child object class window with a parameter regexptitle, so text being changed dynamically depending on the regular expression. I need to check if this window is opened and active using variable. I tried to put there string but it didn't help. Please help me find a solution.
Example of code repeated:
If Window("Excel").Window("Prompts for Project Analysis"). Exist Then ...
If Window("Excel").Window("Prompts for Engagements"). Exist Then ...
Assuming I read your question correctly, you should be able to achieve the goal using descriptive programming with this:
If Window("Excel").Window("regexptitle:=Prompts for.*"). Exist Then
Or if you have at least one version of the window learned in the object repository, add the regexptitle property to the test object details under Description properties, set it to a regular expression and set its value to be "Prompts for.*" - this will cause UFT to recognise all windows of this class with a regexptitle beginning "Prompts for" as this object (assuming the other recognition properties match up as well, and you get to use the OR-friendly object name in your code.
Let me know if that works for you, or if you need further help.

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:

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 am trying to get the icon of an app (doesn't matter which one). I noticed Qt doesn't have something like GDesktopAppInfo and therefore I tried getting it through QSettings from /usr/share/applications/appname.desktop. That's already a problem, because the desktop file might not be there. Anyway, going further to extract the Icon key. Now I dunno how to find the url (notice that I need the url, sure I could make a QIcon, but I need to export it to QML, which would mean another QQuickImageProvider class, anyway, I don't wanna go that way). Is it possible, or is the aforementioned QQuickImageProvider my only solution?
Here is a little guide that might help you find your way. Keep one thing in mind: start with the basic case, get code running and extend it to more difficult cases later.
For now, lets assume the following:
.desktop file is in /usr/share/applications
App icon is in SVG or PNG format
App icon path is absolute
App name is lower case and does not contain whitespace
Input: App name "git-cola"
Read /usr/share/applications/git-cola.desktop
Use a QRegularExpression to get the Icon value
You get an absolute iconPath, e.g. /usr/share/git-cola/icons/git.svg
Have an invokable C++ function that exposes a QUrl to QML
In QML, set the source property of an Image to getIconUrl("Target App")
where 4. looks something like
QUrl MyClass::getIconUrl(QString appName)
{
// get iconPath from appName
return QUrl::​fromLocalFile(iconPath);
}
If things are running, you can add support for
Multiple .desktop locations (there might be a handful or so)
Add support for relative paths
Add support for XPM files
You can use QIcon::fromTheme(QString iconName) to find the icon. It works most of the time but it's not as reliable as gtk
I am developing a extension for Inkscape and would like to set a param value based on a value that is set on a object. For example if the ID of the selected object is set to "myRect" how would I display that value in the extension dialog? Seems to me that there should be a way to tell Inkscape that I want a value displayed here from attribute "id", I have read through the documentation on Inkscapes wiki and searched the web but couldn't find any answers.
I don't think it's possible.
The extension UI is built from the static .inx file. There's no way for your extension code to modify that AFAIK.
It might be possible to have your extension rewrite the .inx file all the time. But I imagine that this would be a horrible horrible approach. Also I'm not sure how frequently inkscape reloads the .inx file.
I am writting log viewer with GTK for Windows. I use GtkTreeView widget to display log records. It contains 3 columns: date & time, event source, event text. For any reason, in event time column strange symbol appears:
I used debugger watch window to see string value, and it doesn't contain any extra characters that can result in this strange symbol appearence.
What are possible reasons of such tree view behavior?
All text used in Gtk+-2.0 widgets needs to be in UTF8 encoding.Text in plain ASCII is automatically valid UTF8, but as soon as you have special characters that do not exist in plain ASCII (usually characters that are not used in the English language alphabet), they need to be in UTF8 encoding.Otherwise you may get what you are getting now.
This is something weird but gtk use to have this problem if you do not use glib library functions. You need to handle all of the strings with this functions. This could be a rendering issue.
for paths you use g_path_get_basename(path);
for dirs you use g_path_get_dirname (path);
for date and time use some of this docs gtk date and time
so it can be displayed properly in the treeview
