Using Tablulator (great product!), I am trying to keep the cursor from resetting to the first editable cell in the table after editing a cell. The replaceData function is updating the data element, and while the scroll position does not change, the cursor is reset. I'm not sure how to do this correctly. The documentation, while great, is silent about cursor position beyond the next(), etc methods, which I cannot quite get to work.
In my vue.js table definition component, I have a watch like this:
watch: {
tableData: {
handler: function (newData) {
this.tabulator.replaceData(newData);
},
deep: true,
}
},
and a cellEdited method inside mounted like this:
mounted() {
let self = this;
//todo Possibly validate that cater tips is less than total tips since cater tips is a portion of total tips
self.tabulator = new Tabulator(self.$refs.myTable, {
height: 380, // set height of table (in CSS or here)
placeholder: 'Click "Load Store Tips" to edit data',
data: self.tableData, //link data to table
reactiveData: true, //enable data reactivity
downloadConfig: {columnCalcs: false},
addRowPos:"bottom",
history:true,
layout: "fitDataFill",
initialSort:[
{column:"storeID", dir:"asc"},
],
//Define Table Columns
columns: [
{title: "Store ID", field: "storeID", sorter:"number"},
{title: "Store Tips", field: "inStore_tips", align: "right", formatter: "money", editor: "number", bottomCalc: "sum"},
{title: "Cater Tips", field: "cater_tips", align: "right", formatter: "money", editor: "number", bottomCalc: "sum"},
{title: "Client ID", field: "clientID"},
],
////////////////////////////////////////////////////////////////////////////
// When a cell is edited, write the data out to the server to ensure it is
// always in a saved state.
////////////////////////////////////////////////////////////////////////////
cellEdited: function (e, cell) {
//self.colPos = cell.getColumn(); //trying to save the cursor pos, but generating error
//self.rowPos = cell.getRow(); // generating error
self.PostTipsEventMethod();
}
});
Here is what I have tried:
Tried capturing the row and column position, and then setting that after the replaceData table render, and after the cellEdited method
Tried using the next() method to move the cursor to the next cell inside the cellEdited method, before and after the replaceData function.
Can someone guide me a bit further on this? I've searched through the tabulator element in the debugger trying to find the row and column numbers of the cell I'm editing, but so far, no joy. I guess I don't understand the lifecycle of the table rendering well enough.
Thank you!

I'm using the Dgrid Selection grid for a grid that uses check boxes for selecting the content. However, only child node of the tree should show the checkbox as the parents are just categories and can't be selected. Previously I used the editor plugin for this, but it created difficulty with clearing selections (specifically, the "clearSelection" method of the grid did nothing). I switched to the selector plugin, so now selecting and deselecting rows works fine, but now I can't seem to figure out a way to hide the check box on some rows and not others.
Original code
var columns = [
editor({
label: " ",
field: "itemSelected",
sortable: false,
width: 33,
canEdit: function(object) {
// only add checkboxes for child objects
return object.type === "child";
}
}, "checkbox"),
tree({
label: "Item",
field: "shortItemId",
width: 150,
shouldExpand: function() {
return 1;
}
}),
{
label: "Grouping Name",
field: "groupingName"
}
];
var itemGrid = new SelectionGrid({
store: itemStore,
style: {
width: '99%',
height: '99%'
},
columns: columns,
sort: [{attribute: "shortItemId", descending: false}]
});
I used the "editOn" parameter of the editor to hide the check box, but the selector plugin only has the "disabled" parameter, which doesn't hide the field at all.
Is there a way I can get the check box hidden using the selector like I did with the editor?
Looking at the dgrid/selector source, it seems that the input is always created and added to the DOM, regardless of whether it has been disabled. Presumably this is to allow it to be flexible enough to enable and disable checkboxes on the fly without the need to constantly re-create DOM nodes. While it is not possible to prevent these nodes from being rendered, it is possible to hide them with CSS, since the cell node is given a class with the format field-{fieldName} (or in this particular case, field-itemSelected):
// JavaScript
var columns = [
selector({
label: " ",
field: "itemSelected",
sortable: false,
width: 33,
// Disable any checkbox that is not of type "child"
disabled: function (item) {
return item.type !== 'child';
}
}),
...
];
/* CSS */
.field-itemSelected input[disabled] {
display: none;
}
sencha touch select field change event not firing if store has duplicate names
suppose my data looks like
options: [{
text: 'Sencha Touch',
value: 'extjs'
}, {
text: 'Sencha Touch',
value: 'senchatouch'
}, {
text: 'Sencha Animator',
value: 'animator'
}, {
text: 'Sencha Designer',
value: 'designer'
}], // options
for the above code the change event not fired for same text
help me?
change event only fires when the new value is actually different from the old value. Not just for select fields, but for all field.
I have a dojo datagrid displaying records. I am displaying image on each row. On click of the image, a request to delete the record should sent to the server. I am setting structure to the grid in Js class file. I have formatted the column to display the image as below.
GridStructure= [
{
name: "Name",
field: "Name",
width: "100px",
rowSelector : '20px'
},
{
name: '',
width: '20px',
field: "",
formatter: function(inValue) {
this.customStyles.push("vertical-align:middle");
return "<img src='images/delete.jpg'/>";
}
}]
how should I handle the onclick event of image and call another JS method which will pass the row details to the business layer for further processing.
Thanks in advance.
I got it working but with a twist. Instead of writing event handling on images, I wrote it on the cell holding that image. So that way I get all the details about row index, the data in the row, everything. that served my purpose. :)
I am using sencha touch 2 and not getting help inside sencha forum, so I hope you guys can help me.
I want to create a list with custom items. In this custom item i want to have a horizontal scrollable listview with buttons as items.
I tried to do it component.DataItem but it does no work for me.
I tried also to add an custom xtype als an item in a list, but this does not work.
I think this is a simple task but sencha touch makes it a challenge for me.
So please help me and show me, how can I get a view like shown in this picture.
Instead of a standard list you are going to want to use Component DataView. Essentially, you are going to need to first define an Ext.dataview.component.DataItem, which is then implemented into the DataView. Below is a simple example of a buttons in a DataView as referenced from the DataView guide: http://docs.sencha.com/touch/2-0/#!/guide/dataview
First create the DataItem:
Ext.define('MyApp.view.DataItemButton', {
extend: 'Ext.dataview.component.DataItem',
requires: ['Ext.Button'],
xtype: 'dataitembutton',
config: {
nameButton: true,
dataMap: {
getNameButton: {
setText: 'name'
}
}
},
applyNameButton: function(config) {
return Ext.factory(config, Ext.Button, this.getNameButton());
},
updateNameButton: function(newNameButton, oldNameButton) {
if (oldNameButton) {
this.remove(oldNameButton);
}
if (newNameButton) {
this.add(newNameButton);
}
}
});
We must extend Ext.dataview.component.DataItem for each item. This is an abstract class which handles the record handling for each item.
Below the extend we require Ext.Button. This is simply because we are going to insert a button inside our item component.
We then specify the xtype for this item component.
Inside our config block we define nameButton. This is a custom configuration we add to this component which will be transformed into a button by the class system. We set it to true by default, but this could also be a configuration block. This configuration will automatically generate getters and setters for our nameButton.
Next we define the dataMap. The dataMap is a map between the data of a record and this view. The getNameButton is the getter for the instance you want to update; so in this case we want to get the nameButton configuration of this component. Then inside that block we give it the setter for that instance; in this case being setText and give it the field of the record we are passing. So, once this item component gets a record it will get the nameButton and then call setText with the name value of the record.
Then we define the apply method for our nameButton. The apply method uses Ext.factory to transform the configuration passed into an instance of Ext.Button. That instance is then returned, which will then cause updateNameButton to be called. The updateNameButton method simply removes the old nameButton instance if it exists, and adds the new nameButton instance if it exists.
Now create the DataView:
Ext.create('Ext.DataView', {
fullscreen: true,
store: {
fields: ['name', 'age'],
data: [
{name: 'Jamie Avins', age: 100},
{name: 'Rob Dougan', age: 21},
{name: 'Tommy Maintz', age: 24},
{name: 'Jacky Nguyen', age: 24},
{name: 'Ed Spencer', age: 26}
]
},
useComponents: true,
defaultType: 'dataitembutton'
});
In your case, rather than using a button for the DataItem, you'll want to use a horizontal scrolling list. Here is an example that I found from this answer: Horizontal scrolling list
var list = Ext.create('Ext.DataView',{
store: store,
itemTpl: new Ext.XTemplate('<img src="{icon}" />'),
inline: { wrap: false },
scrollable: {
direction: 'horizontal',
directionLock: true
}
});
Note that you will probably have to use components in the second dataview as well in order to achieve your buttons with image
I have an itemselecor inside a grid, and i have an combobox that should reload only the store inside the itemselector( the value fields should remain intact)
Here is the itemselector
var grid = Ext.widget('form', {
id: 'grid',
title: '',
width: 600,
bodyPadding: 10,
renderTo: 'itemselectorproduto',
items: [{
xtype: 'itemselector',
name: 'itemselector',
id: 'itemsel',
anchor: '100%',
imagePath: '/ux/images/',
store: store,
displayField: 'Nome',
valueField: 'ID',
value: vitrine,
allowBlank: true,
msgTarget: 'side'
}]
});
I tried to call the normal store.load(), but it have no effect and it shows no error on the console
If needed i will post more of the code, but i think just this should be enough
Thanks,
Looking through the code if ItemSelector it doesn't look like it supports any changes in the store once it's been binded. It basically creates local copies of the data. And if you call bindStore method to assign different store - it will erase your selection.
You can always improve code in ItemSelector to allow such behavior. It should not be a problem. You can subscribe to datachanged or load event of the store when binding to it, and then handle situation when store data is changed.
Actually i think the best way to do such thing is using ItemSelector`s "populateFromStore". Sure except of extending item selector. In case of extending you should look on the "onBindStore" function of the ItemSelector.
onBindStore: function(store, initial) {
var me = this;
if (me.fromField) {
me.fromField.store.removeAll()
me.toField.store.removeAll();
// Add everything to the from field as soon as the Store is loaded
if (store.getCount()) {
me.populateFromStore(store);
} else {
me.store.on('load', me.populateFromStore, me);
}
}
}
So as you see in case of the empty store it hooks to the load event. And it should be like this:
onBindStore: function(store, initial) {
var me = this;
if (me.fromField) {
me.fromField.store.removeAll()
me.toField.store.removeAll();
me.store.on('load', me.populateFromStore, me);
// Add everything to the from field as soon as the Store is loaded
if (store.getCount()) {
me.populateFromStore(store);
}
}
}
