Android NumberPicker with Formatter doesn't format on first rendering

由 a 夏天 提交于 2019-11-27 12:39:08
I have a NumberPicker that has a formatter that formats the displayed numbers either when the NumberPicker spins or when a value is entered manually. This works fine, but when the NumberPicker is first shown and I initialize it with setValue(0) the 0 does not get formatted (it should display as "-" instead of 0). As soon as I spin the NumberPicker from that point on everything works. How can I force the NumberPicker to format always - Both on first rendering and also when I enter a number manually with the keyboard? This is my formatter public class PickerFormatter implements Formatter {

How can I change the background color of a cell in a jqgrid custom formatter?

由 瘦欲@ 提交于 2019-11-27 07:54:47
I can change the text color by doing this in jqgrid custom formatter: function YNFormatter(cellvalue, options, rowObject) { var color = (cellvalue == "Y") ? "green" : "red"; var cellHtml = "<span style='color:" + color + "' originalValue='" + cellvalue + "'>" + cellvalue + "</span>"; return cellHtml; } but I want to now change the background color of the whole cell (instead of the text color). Is this possible? Oleg If you want use <span> element inside of the custom cell formatter you can return from the custom formatter return '<span class="cellWithoutBackground" style="background-color:' +

jqGrid - format ratio field as percent value

由 陌路散爱 提交于 2019-11-27 05:13:31
My server code transfers some column as a ratio value, 0.0 to 1.0. I need to format and edit it as a percent. I would like to do it on JavaScript side, without modifying server-side. So if I add a custom formatter to just multiply the value by 100, display works as expected. Moreover, when I hit edit button, inline edit box also displays value as percentage. The trouble starts when I save - the value gets converted with formatter one more time , giving me things like 10000. So OK, I need symmetry here, so I create an unformatter which just divides value by 100. But that doesn't work too - now

Numeric TextField for Integers in JavaFX 8 with TextFormatter and/or UnaryOperator

由 好久不见. 提交于 2019-11-26 22:42:23
I am trying to create a numeric TextField for Integers by using the TextFormatter of JavaFX 8. Solution with UnaryOperator: UnaryOperator<Change> integerFilter = change -> { String input = change.getText(); if (input.matches("[0-9]*")) { return change; } return null; }; myNumericField.setTextFormatter(new TextFormatter<String>(integerFilter)); Solution with IntegerStringConverter: myNumericField.setTextFormatter(new TextFormatter<>(new IntegerStringConverter())); Both solutions have their own problems. With the UnaryOperator, I can only enter digits from 0 to 9 like intended, but I also need

Can the Eclipse Java formatter be used stand-alone

由 北城以北 提交于 2019-11-26 16:28:54
问题 Is there a way to use the formatter that comes with eclipse, outside of eclipse? I would like to format some java files using my formatter.xml file that I have configured using eclipse. Does anyone have any code examples that would allow me to do this? I would also like to use this standalone, so the specific jars that are used would be nice. 回答1: Apparently you can directly invoke Eclipse's code formatter from the command line. 回答2: Never tried to pull something like that off, but I remember

How to properly format currency on ios

问题 I'm looking for a way to format a string into currency without using the TextField hack. For example, i'd like to have the number "521242" converted into "5,212.42" Or if I have a number under 1$, I would like it to look like this: "52" -> "0.52" Thanks 回答1: You probably want something like this (assuming currency is a float): NSNumberFormatter *numberFormatter = [[NSNumberFormatter alloc] init]; [numberFormatter setNumberStyle: NSNumberFormatterCurrencyStyle]; NSString *numberAsString =
