In Qt, I'm aware of the tr() function that you can use to internationalize string literals in the code. But how does it work for text that I have entered in a widget's properties, such as currentTabText in the screenshot below? Do I have to set such properties in code too and use the tr() function or is there an easier way to do that?
Nothing else is needed, Just make sure the attribute "translatable" is set to true(expand the currentTabText to see that)
By nothing else I mean nothing extra is needed apart from what is already being needed for tr() to work.
So I assume you already know about QTranslator , installTranslator(), lupdate and linguist etc.
Just open the drop down list of currentTabText, and make sure that translatable checkbox is checked.

Hy,
i m working on a qt application styled by a stylesheet, set like
QApplication qApplication(argc, argv);
QFile styleFile("myStyleFile.stylesheet");
bool check = styleFile.open(QFile::ReadOnly);
qApplication.setStyleSheet(styleFile.readAll());
the important window of this application uses a QGraphicsScene (which items are not styleable with stylesheets).
But i wannt a unique look.
So the questions are:
1.) Is there a way to access the set stylesheet properties ( like getProperty("QMenu::item:selected") )?
2.) or does anyone know a css-syntax to xml-file tool? (than one could access the set properties with the qt xml/dom support)
I know that some special properties can be accessed like
QColor mainWindowbackgroundColor =
palette().color( QWidget::backgroundRole() );//Get the backgroundcolor set by stylesheet.
but i am searching for a way to access ALL set properties.
Thank you!
I think you will need to use private Qt classes to do this. This is generally not a good idea as the interfaces are internal and subject to change.
In the Qt (4.8.4) sources \src\gui\text\qcssparser_p.h header the QCss namespace is declared.
Whilst I haven't tried this, it looks like you will need to create a QCss::Parser, call parse to get a QCss::StyleSheet. This object contains the parsed data including a vector of QCss::StyleRule which matches QCss::Selector and QCss::Declaration together, have a look at the comment above the QCss::Declaration to see how it is all broken down.
Final Warning: Using Qt private interfaces is liable to cause maintenance problems - don't do it without a very good reason.
I am using QFileDialog as
filename = QFileDialog::getExistingDirectory(this,"Select Image File: ",dataDir,0);
I want that I can check files inside folder before selecting it. function getExistingDirectory() is setting QFileDialog::ShowDirsOnly as a default option. I checked in docs there is no any option that do opposite of this. So I set last parameter 0. But now it is not using native dialog. I want to use native dialog with this. I have no clue how to do this cause no flag found in options for UseNativeDialog. Please help.
Try creating the file dialog on your own, something like:
QFileDialog dialog(this);
dialog.setFileMode(QFileDialog::Directory);
dialog.setViewMode(QFileDialog::Detail);
dialog.setDirectory(datadir);
dialog.exec();
The code by Sebastian should create a native dialog, unless you make a line such as:
dialog.setOption(QFileDialog::DontUseNativeDialog, true);
However, I have not been able to get this working under Windows, even though the documentation says that the QFileDialog::Directory option should display files by default. Not only that, but doing:
qDebug() << dir_selector.testOption(QFileDialog::ShowDirsOnly);
displays false on my system, indicating that there is probably a bug somewhere.
I fear I may be overlooking something very obvious, but I'd be grateful for any suggestions. I have a plain text file called 'settings' in a Ploneformgen form folder in Plone. The code below successfully alters the text in this file when I put it in a Python script called when the form is viewed using an override in one of the form's fields (e.g. Default Expression in a string field).
obj = context['settings']
obj.setText('Some text:2;More text:2')
obj.reindexObject()
My problem is that I would like to be able to modify the text in 'settings' using either a Custom Script Adapter or a script called using the After Validation Script override of the form. Neither of these work (and overrides in individual fields for validating the field don't seem to allow this either).
Is there some reason why setText() works in some places and not in others (the line obj = context['settings'] doesn't appear to be a problem)? What am I missing?
As far as I can see this isn't a problem of permissions, and I'm a bit baffled that code that works if called when the form is viewed doesn't work if called when the form has been submitted.
I can create a new text file and add text to it using scripts called in these ways no problem: it seems to be a specific problem with calling setText() on an existing file.
The solution is to set the mimetype explicitly when calling setText():
obj.setText("Some text", mimetype='text/plain')
or
obj.setText("Some text", mimetype='text/html')
as appropriate. I don't know why this works, but it does.
I want to change my rehosted activities look to:
Already tried ActivityDesignerTheme
Need to do it without using WorkflowViewElement because I don't want to lose it's behaviors (breakpoint, expanding).
If it's not possible, is there a way to change ActivityDesigner header background color?
#Will
I was annoyed too by the default behavior of the ActivityDesigner header when editing the DisplayName (especially the part where it positions the caret at the beginning of the string). I used Reflector to peek (System.Activities.Presentation.dll) at the implementation and I noticed that some of this behavior is defined in OnApplyTemplate. By just overriding this method in my custom designer class and NOT calling base.OnApplyTemplate(), I was able to make the DisplayName read only in the header (in my case that was all I needed, but I think one can play with some custom event handlers in there and tweak the behavior).
#Davi Fiamenghi
Digging around some more with Reflector in the same assembly, I found the controls used in OnApplyTemplate defined under system/activities/presentation/workflowelementdesignerdefaulttemplate.baml (System.Activities.Presentation.g.resources). That seems to be the default control template used for ActivityDesigner (<ControlTemplate x:Key="WorkflowElementDesignerDefaultTemplate" x:Uid="ControlTemplate_1" ControlTemplate.TargetType="{x:Type swd:ActivityDesigner}">). I guess one way to change the header color would be to try to "re-create" this template in your application and set it explicitly in your custom activity designer. Of course it's more involved than just copying it, since it appears to be referencing other resources defined in that assembly.
Hope this helps.
Flex 3 question:
I trying here to avoid having to bind resources to all my components labels ( ie a button) and find a way to have this automated.
Problem:
It corrupts the layout in design mode to bind directly in the mxml label="{resourceManager.getString('myResources', 'submit')}" and makes the design view useless. but when declaring bindings elsewhere, in actionScript or via a bind tag, it is counter productive and prone to many errors and miss.
Proposition:
I would like to create my own button that automatically invoke resources to localize a button label. So the author puts "Submit" in the mxml description of my button, and when running it would take the value of the label ie "submit" and use resourceManager.getString('myResources', 'submit').
but I can't find the way to override the set label function, Is it possible if yes how? else how can I go about it?
Maybe I am missing an essential process here that would make the use of resources more elegant, as well as how to override such thing as a button's label.
Thanks for your advices.
Create a component called MyButton, extending Button. Then use this:
override public function set label(value:String):void {
super.label = resourceManager.getString('myResources', value) || value;
}
Assuming the resource manager returns "null" or "undefined" this will work, and will only replace the value if it exists in "myResources".
If you don't want to override every component you need to do this with, then you can add a FlexEvent.CREATION_COMPLETE event on every component. Then use a single generic function to do your label localization.
