I'm working with CodeMirror 6 and I'd like to render a non-editable code sample where you can modify one or more sub-strings of the sample value.
I am already set up to identify the ranges within a code sample where I'd like the text to be editable. I'm also aware of the Decorations reference, but it doesn't seem like you can simply mark a decorated range as "editable".
Currently, when constructing decorations, I just look at the decoration object to determine if a range is editable, and if it is insert an HTML text input widget, otherwise insert a decoration that styles the range such that it looks editable. Here's a little bit of what that looks like:
const positionLineStart = createPosition(item.startColumn);
// This range is being edited, so use a widget that inserts the text input
if (item.editing) {
const editableFieldWidget = Decoration.widget({
widget: new EditableFieldWidget(item),
});
return editableFieldWidget.range(positionLineStart);
// The range is not being edited, but is editable, so insert a mark deco
// that makes it look like you can click into it
} else {
const positionLineEnd = createPosition(item.endColumn);
const inlineDecoration = Decoration.mark(attributes);
return inlineDecoration.range(positionLineStart, positionLineEnd);
}
But going this route makes things pretty complicated: I need to handle a bunch of events - focus, blur, Enter, Escape to determine the new range value, resizing the range after saving to reflect the new value, communicating the value of the text input back to the code sample and replacing that range with it, etc.
I almost wish that I could simply set contenteditable on a decoration that exists within a non-editable CodeMirror instance - that way it's all edited in place, can still be copied out, and doesn't require swapping decorations.
Is what I'm after possible?

I have a Typo3 server. On that I created some different content elements with mask.
In this elements there are often repeating content, like texts or other stuff.
So the editors make a new element in the backend, there they can add a headline and as much text parts as they want.
Often it looks like this:
Thats good, the editor can see a "preview" of the textparts. In this example "Karriere,Partner...". This naming happens automatically.
My Problem is, some times there arent any titles. Its always "No title". As an editor its quite hard to find the right dropdown to edit some stuff, you mostly have to open all dropdowns and search for the right one.
Its look then like this:
In both elements there are some string inputs that are very good for the title.
So my question is, how is mask gonna choose the title? Its not the first string input.
And secondly, can I tell Mask that they have to choose input field XYZ as title?
Heyo
Yes, you can tell Mask which field to use as a title for inline elements (like repeating contents). When you're setting up a new Mask element, right below the "Label" field of the repeated inline element, there is a field "Field that should be used as label for inline element (starting with tx_mask_)". This will be used as the title that is displayed in the backend. In the placeholder of that field, it explicitly says that "If empty, first field is used".
So, if your inline element has a field "my_awesome_header" which you would like to use as the title in the backend, set the above to "tx_mask_my_awesome_header".
I am not certain as to why it does not display anything in your second example. It might be that either the first input field is not a string, or the first input field is a string but it is empty.
I hope this helps. Let me know if you need further clarification.
Edit: Since that question came up, it should be possible to set a static default title to the containing Mask element using mod.wizards.newContentElement.wizardItems.mask.elements.[name of the mask element].tt_content_defValues.header = My awesome static title. As I said in the comments, though: I always give my Mask elements a header field and let editors fill that in.
I have a multipage form with more than 40 fields spread over multiple tabs, and grouped in collapsible fieldsets.
Now I have the case that upon form submission, a field is detected as invalid, and I want to find the field for the user, bring it into the visible area and focus it. So I have to switch to the right tab, open the fieldset if applicable, scroll the field into the visible area and focus it.
I would guess ExtJS has a function for this, but I don't find one. My code:
// Get first invalid field. C&P from Ext.form.Basic.isValid function
var invalidField = me.getForm().getFields().findBy(function(f) {return !f.isValid();});
if(invalidField) {
// TODO: Bring the field to front.
// Now focus the field:
invalidField.focus();
Is there a builtin function available?
Ext JS does not provide a built-in method for doing this specifically, but it does provide all of the necessary utility methods and supports animations. At a minimum, ensuring the form is configured as scrollable, setting the active tab, and focusing on the invalid field is enough to scroll to correct position. I created a fiddle example demonstrating a solution.
Sencha Fiddle: An Example of Scrolling to an Invalid Field in a Tab
tabPanel.items.each(function(tab) {
var formPanel = tab.down('form');
formPanel.getForm().getFields().each(function(field, index, length) {
if (!field.isValid()) {
tabPanel.setActiveTab(tab);
// Focusing an element will set the correct scroll position.
// However, an animation can help the user follow along.
formPanel.setScrollY(field.getPosition()[1], true);
field.focus();
return false;
}
return true;
});
});

GWT newbie here. I have found that when I make a TextArea read-only useful features such as dynamic expansion and even word-wrapping stops working. My intention was to move a string from one text area, append it some way to some more strings, and then add this string into my read-only TextArea. I have doing something like this:
// Temporarily enable the field to set the value of the TextArea
logTextArea.setEnabled(true);
String remarks = // my string to add into the box
if (remarks.length() > 0) {
logTextArea.setEnabled.setValue(remarks);
}
// set read-only again
logTextArea.setEnabled.setEnabled(false);
I also have to work out how many lines I now span and explicitly set the height of the box (via setVisibleLines()). I have now found that it does not word-wrap, so I've had to add some more horrible bodge-code to further split up this string.
So I'm writing code to emulate functionality that comes for free on a normal writable TextArea. Has anyone else found this issue after setting a text-field read-only? Is there another widget I could possibly use to display a list of read-only strings that will auto resize and auto wrap for me?
Many thanks for your time,
tom
Text Area is fine for re-sizing and auto word wrap, even you have your text
area as read only.
Tested now by creating a test project for gwt and it is working fine.
Also Word Wrap is the default behavior of Text area if you want to turn it off then you need to explicitly do this "getElement().setAttribute("wrap","off");
Using the report-designer of Reportbuilder i want to add a long fixed text to my report with one or more included fields inside the text. Of course these fields should be filled with actual data, adjusting the text.
I remember I have done such a thing in the past, but cannot remember how. I thought you could accomplish this with a Text-field and something like 'This is the text and here {fieldname} fielddata is inserted', but that doesnt seem to work
Can anybody help?
Using reportbuilder 15.04
Response from Digital Metaphores:
Use the RichtText component! By setting MailMerge to true, you can add
datafields to text in the richtext editor
This adds the reference to the fielddata as a xml tag. Adding the fields Name from pipeline plData can be done like this:
<dbtext datapipeline='plData'>Name</dbtext>
Fill in the fixed text, then (making sure the focus is set to the text box, I.E. you have the flashing pipe cursor) right click in the place you want the data field to go, and click Create Placeholder.
In the Placeholder properties window give it a Label so you know what it is, then use the "Value" field to define what data from your datasets you want to be brought through.
You should end up with the Label you set in square brackets, like [Example] within the set text.
I want to validate that user cannot change spinner value manually by typing in text box of spinner.
For example a field sales multiple = x which I fetched from server not fix.
and displays a spinner field with limitation of like bellow
spinner.setMinValue = x
spinner.setIncrement = x
spinner.setValue = x
so user forcefully select a value which is multiple with x. e.g. if x=3 the user have to enter 3,6,9... and so on.
So here my issue is if I type a 2 in spinner field text box. GXT widget accept that value.
Posible solutions:
Is there any predefined properties of spinnerfield that i forget to set it?
Is there any predefined validator for this?
Can I set text box of spinner field read only by css so user cannot focus on text box but still change a value.
If none of above how to achieve manually?
i've searched a bit in the different classes and I don't see either a precise method which would set what you want.
Don't know about one, and even with one, a validator doesn't change the value in the input field, but maybe it's enough for your needs.
You can disable the text input by calling setEditable(boolean) on the spinnerfield (testSpinner.setEditable(false);)
Maybe you could search around the IntegerPropertyEditor, I haven't tried but as long as a new Spinner is like this:
SpinnerField<Integer> testSpinner = new SpinnerField<Integer>(new NumberPropertyEditor.IntegerPropertyEditor());
you can seen that there is another Constructor for IntegerPropertyEditor, which takes a "NumberFormat" param, but there is no NumberFormart() constructor, so I'm not sure about how you create your own one, but that could be an idea (to format numbers in the input to be a multiple of the increment).
The last option would be that Sencha forgot this possibility and that you should report this as a "bug" on the forum ?
Hope to have helped a bit, good luck :).
