I am trying to get somehow value of text = getTextToDisplay(cell, gc, rectangle.width, text); parameter from TextPainter#paintCell() into NatTableContentTooltip#getText(). I did not find the value in event or cell parameter of the getText() method. I need some condition, if displayed text is the same as a value in cell (not cutted for narrow cells). Thanks for a hint anybody!
The simple answer is, you can't. It is a painter that renders text according to table/cell states.

Is it possible to have a grid column containing multiple types inside of it based on the value of a cell? Where each cell is rendered based on value. For instance, with in the same column a cell could be of type 'text' or 'datetime' or 'list' etc... and for each type I can use built in inline-editing? See image illustration below. Basically a key/value editor where the value column need to contain more than one 'type. Please post a sample answer.
It's possible, but you cannot rely on standard funtionality.
The idea of a w2grid is to assign a renderer to a column and render all cells of the same column in the same way.
You could implement a render function for your column and then generate the HTML for each cell based on those arguments:
http://w2ui.com/web/docs/1.5/w2grid.columns
Or you could override getCellHTML() for your grid.
Have a look at the implementation of getCellHTML() to see what awaits you if you want to customize it:
https://github.com/vitmalina/w2ui/blob/master/src/w2grid.js#L7396
Although it was a hack solution I ended up creating multiple grids aligned vertically each with a property & value column but the value column's 'type' attribute is different for each grid based on the w2ui framework out of box functionality I Desired for it. Each Grid is also separated by the header without padding to give it a feel like it is one grid. See Image below. now obviously the draw back of this is you cannot sort on all the fields but this is not required in my use case.
I`m trying to add addValueChangeHandler function to a TextBox inside a flexTable.
But when I add this code:
int rowIndex = tableImages.getCellForEvent(event).getRowIndex();
I use this method to know the current row in case of a ClickEvent.
the method is not acceptable for ValueChangeEvent,
so how can I know what is the row Index for the changed cell?
Thank you.
Well yes, because it needs a Cell itself, not a TextBox or event value.
What you can do, is:
Get the event Source via event.getSource()
Cast it to Widget at least (though it's safe to assume it's a textBox) Widget sourceWidget = (Widget)event.getSource();
Get the source widget's element's parent sourceWidget.getElement().getParent();
This way you'll acquire the actual <td> cell your textBox nested in.
Then you can getCellFormatter of your table and find the index of the cell in a loop, comparing the <td> element you got with the cells of your table.
Please tell me if it solved your problem
I want to display a value in a textField even if the value is larger that the width of the textfield. I don't want it to be truncated.
Is it possible?
Thanks.
You can enable wrapping text by setting the textField stretchWithOverflow attribute to true. This works as long as the expression time is NOW. It does not work for delayed evaluation.
I have an RDL with a table/textbox visibility set to:
=iif(Fields!question_caption.Value = "OBJECTIVE 1",false,true)
I am trying to make this textbox display the value named "narrative" only if the question_caption record = "OBJECTIVE 1". How can I do this? Currently this textbox displays nothing with the above logic. I have the narrative field stored in a Placeholder if that makes any difference.
Here is some sample data for you:
create table #dummy_data
(
question_caption varchar(max),
narrative varchar(max)
)
insert #dummy_data values('1st week dates','week 1'),('2nd week dates','week 2'),('3rd week dates','week 3'),('OBJECTIVE 1','obj 1'),
('5th week dates','week 5')
select * from #dummy_data
I don't see anything wrong with your visibility expression. However, in your question, you're discussing two separate things as one (i.e., visibility & displaying a value in a placeholder).
The hidden property will show an object (tablix, textbox, image, chart, container, etc) if the expression returns false and will hide an object when the expression returns true. When I say hide, I mean that it will remove the object from the grid and, if all is setup properly, the surrounding objects will be shifted to fill the now empty space of the hidden object.
To display (or not) a value is an entirely different thing. To show or hide a value, you would put the following expression in the value property of the placeholder:
=IIF(Fields!question_caption.Value = "OBJECTIVE 1",Fields!narrative.Value,"")
Notice that I've set it up such that if the desired value of the question_caption field is present, it will display the value of the narrative field. Otherwise, it will return an empty string. This will maintain the layout of the report but simply display the desired value or an empty string, based on some criteria.
As for the issues you're current experiencing, I'm not sure why that would be happening. I would first check that you don't have a typo in the Objective 1 hardcoded value in your expression.
If this doesn't help, please comment and let me know some more information about your problem and I'll do my best to help.
I am new to gwt and I am trying to check if the dynamic string document id that i am retrieving will will fit on the gwt label or not. Now I am checking for the number of characters and if the number exceeds 15 I am appending ... after 12 characters and displaying the actual id in the tooltip. I need to know how do i achieve this without calculating the number of characters. Please help
The width of a label does not only depend on the string size, but on the font used.
You could write you string in a temporary label attached to the dom and query the size using the method 'getClientWidth' of the element or gwtquery, and remove recursively the last character until you get the appropriate size.
In my opinion the easier way would be to use css and define a fixed width of your label and set the property overflow to hidden, so you see just the chars which fit in the label and you dont have to deal with a different string.
