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 :).

I want a button from the command line bar to be visible or invisible depending on whether a record has been selected in the lookup field from the main form or not.
If no record has been selected, then the button should be displayed. Otherwise not.
For this problem, I want to use the Power Fx in PowerApps, but I haven't found a command yet, which shows me the content or something like that of the lookup field. Other field data types like text have worked without problems.
With Javascript, I already managed it without problems, but I would like to do it also in PowerFx if that should work.
Screenshot: https://i.stack.imgur.com/uqDJ6.png
The records come from the Table Company, where the attribute is Companyname.
Commands where I think they might work:
If([Selected Record];true;false);If(IsBlank([Selected Record]);true;false);If(IsBlankOrError([Selected Record]);true;false);If(IsEmpty([Selected Record]);true;false)
I guess there are 2 scenarios:
The Lookup form control element is a Dropdown with a Selected output property. Then your approach would work like If(IsBlankOrError(DataCardValue1.Selected),true,false)
If your form control element is a ComboBox then you could use If(CountRows(DataCardValue1.SelectedItems)>0,true,false) or the above described IsBlankOrError.
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 need to slightly modify a ag-grid row after it has been rendered. In ag-grid, the actual HTML elements are not necessarily persistent, so manually-set styles may fall off.
For one thing, I have to modify the selection checkbox to set its tabindex to -1. This can technically be done in the cellRenderer callback, although it looks quite hacky. (The checkbox can be found at params.eGridCell.children[0].children[0].wrappedElement.)
But I also have to add a CSS class to some rows to highlight them based on external criteria. I haven't found a way to do this at all.
The best solution would seem to be using some sort of after-rendering callback, but to my knowledge no such thing exists.
I found a couple of related questions, but they were both resolved via cellStyle, which would not suffice here:
Row formatting in ag-Grid
How to provide a background color for an entire row in ag grid based on a certain value in a column?
You have not 1 but 3 options:
getRowClass(params):
Callback version of property 'rowClass'. Function should return a string or an array of strings.
getRowStyle(params):
Callback version of property 'rowStyle'. Function should return an object of CSS values.
processRowPostCreate(params):
Allows you to process rows after they are created. So do final adding of custom attributes etc.
In this last one you have the row in params.eRow.

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");
I have a data-grid and three column in it. one column is type of DataGridViewComboBoxCell, three items are in this grid combo box, now i have to invoke selection index changed event to change value according to combo value change in grid.
also help me to make a new event ....
please help...
thanks
I really can't understand your question.
But maybe these informations can help:
A ComboBoxColumn has always two kinds of controls. A presenting one (in most cases a label) which is individually for each row. And a editing one that will be shared for the whole column. So take a look into this documentation and the IDataGridViewEditingControl Interface.
Maybe these will give you a starting point on how to solve your problem.
In the Load event for the form, you need to get the cell that you want to add the handler to and cast it as a regular combo box. You can then add the event handler on SelectedIndexChanged, but it must be done programmatically, and depending on the language you are using.
