Dear stackoverflow community;
I've got a QTextBrowser widget, I set a text on it via QTDesigner, now I need to set another line of text to it via code.
My code:
self.ui.textStatus.append('text')
I don't find a working append method for a QTextBrowser object, any idea how to do so?
Kind regards;
self.ui.textStatus.setText(self.ui.textStatus.text() + ' text')
Anyway, from what I can read in the documentation QTextBrowser inherits from QTextEdit and it has the append() method (just tried in a dummy app)..

I have some GWT code here. I am trying to change the background color of a widget:
this.getElement().setAttribute("backgroundColor", backgroundColor);
this.getElement().setPropertyString("backgroundColor", backgroundColor);
this.getElement().getStyle().setProperty("backgroundColor", backgroundColor);
Usually in code I can tell by the name of the function what the code does... but in this case all three lines of code looks the same and "read the same"! (Reading the javadoc did not help either.I went to the javadoc because that usually helps me understand what code does. The javadoc did not help.)
My question to you is: Please explain what is the differences between these three lines of code (for instance why do you need to call getStyle())? Why does the last line work?
this.getElement().getStyle().setProperty("backgroundColor", backgroundColor);
is the only line that access the actual style information, properties and attributes manipulate the element directly and don't have anything to do with the Style that is associated with an element.
And just as an addition, you should really be using a style sheet and changing the style instead of setting inline this way.
It is the difference between
<tag backgroundColor="#f0f0f0">
and
<tag style="background-color:#f0f0f0">
This is somewhat of an educated guess...
Line 1 you are accessing the element's attributes not the styling attributes.
Line 2 would access properties on the element not the styling.
Line 3 actually gets the styling properties and then changes them accordingly.
I have a need to create a <br/> tag in the display label for a menu item generated using Zend_navigation, but don't seem to be able to find a way to do so.
My navigation item is defined in the XML config as:
<registermachine>
<label>Register your Slitter Rewinder</label>
<controller>service</controller>
<action>register</action>
<route>default</route>
</registermachine>
I want to force a tag in the output HTML between 'your' and 'slitter', such that it appears on two line as below:
Register your
Slitter Rewinder
However, I can't seem to do it. obviously using in the XML breaks parsing, and using html entities means that the lable is displayed as:
Register your <br/>Slitter Rewinder
Has anyone had experience of this that can offer advice?
Thanks in advance!
there is no such option built-in you have to use a partial
$partial = array('menu.phtml', 'default');
$this->navigation()->menu()->setPartial($partial);
echo $this->navigation()->menu()->render();
http://framework.zend.com/manual/en/zend.view.helpers.html#zend.view.helpers.initial.navigation.menu
you may also try a hack with <label><![CDATA[Menu label<br/>Second line]]></label>
I found a (hacky) solution:
I updated my navigation.xml to use {br} tokens wherever a <br/> tag is required, and then amended the base Zend/View/Helper/Navigation/Menu.php file as follows:
within htmlify function, changed
$this->view->escape($label)
to
str_replace("{br}", "<br/>", $label)
I could (and probably will) override the Zend Library Menu View Helper with my own at some point, but this at least cover it for now.
there is a escapeLabels boolean used to convert html tags and it's true by default.
You can set your navigation like this
$this->navigation()
->menu()
->escapeLabels(false)
->...

I have a program built with VBA, in access.
I have a form with the field chDate and I need to get the value of the field in a module file named Global (not class module).
I tried to access it but I think I get empty value, string. not error.
I'm no expert with VBA, its new to me (I have experience with VBS).
Can someone please help me and tell me how can I access the value of a form field via module file?
Thanks!
If you can provide some sample code, it might help us in trying to get you a solution.
Here's what might work:
Dim an object as an instance of your form, and set the instance to a new instance. These two lines will do that (assuming the form is called frmForm)
Dim theForm as frmForm
Set theForm = new frmForm
then Show that Form:
theForm.show
The form will get the focus, so you can populate the fields. At that point, once the form is hidden, your code should be able to pull the field as such:
var1 = theForm.txtFormField.Text
However, if you unload the form in code, all variables directly tied to the form will be lost. In that case, you might want to follow Oneide's example, and set a global variable to the value of the form field. You can do this in one of the form's event handlers.
Let me see if I can recall my Access days. In your global module you should access the form field be prefixing the form name i.e.
var1 = Form1.txtFirmField.Text
As far as I know, you're trying to get the data the wrong way.
Anytime you would try to get your form data, from a standard module, your form probably will already be closed or, if you're not opening it as a restricted window, the value will not be ready yet.
Anyway, if you could get pass through all the difficulties above, you're probably coding in a not standard / right way.
Remember that VBA is an event driven language, and you would be better using it's strenghts rather than fighting against them.
As a final word, if this is just a casual coding, I suggest you using a global variable and make de Code Behind Form have set it up on control's change event.
If you're not sure what I mean, please leave a comment and I'll try to explain it better.
And, if you don't mind, let us know more about your starting code to get better answers.
I am extremely new to Zend Framework, In registration form, i need label text in two line. For Example:- In the case First name, I need to display like below:
First
Name:
How can i implement this? Please anyone help me!!!
By default, input fields labels are being escaped by Zend_View_Helper_FormLabel. However, you can easy switch this off:
$yourTextInputElement->getDecorator('label')->setOption('escape', false);
This way you can use labels as e.g. $yourTextInputElement->setLabel('First <br/> name');.
What about this nifty solution ?

The best way is probably to use Description decorator, or subclass one of other standard ZF decorators.
Yanick's CSS solution might be a good choice too, depending what are you trying to do.
I'm currently using Zend_Filter_StripTags in a commenting system, but stuff kinda breaks when '<3' is entered. StripTags doesn't seem to be smart enough to realize that it's not an HTML tag, and creating the filter as "new Zend_Filter_StripTags(array('3'))" doesn't seem to work either.
Should I pass the input through a regexp first, or is there a way to get Zend_Filter_StripTags to straighten up and fly right?
Ended up writing a Zend_Filter class that was basically a wrapper for HTMLPurifier. Works perfectly, because HTMLPurifier is a LOT smarter than striptags.
I'm not familiar with Zend much, but if you want stuff like <3 to be allowed, just do htmlspecialchars instead of strip_tags on it.
What you want is Zend_Filter_HtmlEntites most likely.
See: Zend_Filter_HtmlEnties
The problem with htmlspecialchars and Zend_Filter_HtmlEntities is that if you're trying to strip out all html tags ( like 'a' and 'img', etc ), then instead of stripping them, you end up with that markup in your output.
Take comments on a blog for example. If you use htmlspecialchars or Zend_Filter_HtmlEntities, in a comment where someone tries to use html to enter a link you end up with that markup showing up when you display the comment. But if you use strip_tags or Zend_Filter_StripTags you end up mangling the comment, as neither is smart enough to realize that '<3' isn't a tag, and just strips everything from '<3' until the end of the comment ( or until it finds '>' ).
It would be nice if Zend had something like HTMLPurifier, where it actually checks and validates the input before stripping tags. This means that stuff like '<3' gets left alone, where as stuff like 'Awesome Site' becomes 'Awesome Site'.
This is a problem I'm trying to work around, and at the moment it seems like I'm going to end up writing my own Zend_Filter class that's basically a wrapper for HTMLPurifier.
