The idea is to have a HBox container under the MultiComboBox control to which selected tokens will be pushed. I have followed different tutorials and couldn't get a success. A multiComboBox is simply now shown.
The idea:
Simplified (testing) implementation of custom control:
sap.ui.define([
'sap/m/MultiComboBox',
'sap/m/HBox'
], function (MultiComboBox, HBox) {
'use strict';
/**
* Constructor for a new MultiCombobox with tokens.
*/
return MultiComboBox.extend('drex.control.DropDownWithTags', {
metadata: {
aggregations: {
_tokensContainer: { type: 'sap.m.HBox', multiple: false }
},
},
init: function () {
MultiComboBox.prototype.init.apply(this, arguments);
this.setAggregation('_tokensContainer', new HBox());
},
_addToken: function () {
this.getAggregation('_tokensContainer').insertItem({text: 'test'});
},
_handleSelectionLiveChange: function(oControlEvent) {
this._addToken();
MultiComboBox.prototype._handleSelectionLiveChange.apply(this, arguments);
},
renderer: function (rm, DropDownWithTags) {
rm.write('<div');
rm.writeControlData(DropDownWithTags);
rm.write('>');
rm.renderControl(DropDownWithTags.getAggregation('_tokensContainer'));
rm.write('</div>');
}
});
});
XML (no change, except for a name, could that be a problem?). Adding HBox aggregation to it does not help.
<drex:DropDownWithTags
items="{
path: 'diseaseList>/allDiseases'
}"
selectedKeys="{filterModel>/disease}"
selectionFinish="onSelectDisease">
<core:Item key="{diseaseList>id}" text="{diseaseList>Name}"/>
</drex:DropDownWithTags>
Any idea why it happens ? I cannot see my mistake.
there are many ways to do this. here is one way
sap.ui.define([
'sap/ui/core/Control',
'sap/ui/core/Item',
'sap/m/MultiComboBox',
'sap/m/HBox',
'sap/m/Text'
], function (Control, Item, MultiComboBox, HBox, Text) {
Control.extend('DropDownWithTags', {
metadata: {
aggregations: {
combo: { type: 'sap.m.MultiComboBox', multiple: false },
_hbox: { type: 'sap.m.HBox', multiple: false }
},
},
init: function () {
Control.prototype.init.apply(this, arguments);
this.setAggregation('_hbox', new HBox({
items: [
]
}));
},
renderer: function (rm, oControl) {
rm.write('<div');
rm.writeControlData(oControl);
rm.write('>');
rm.write('<div>');
rm.renderControl(oControl.getAggregation('combo'));
rm.write('</div>');
rm.write('<div>');
rm.renderControl(oControl.getAggregation('_hbox'));
rm.write('</div>');
rm.write('</div>');
},
onAfterRendering: function() {
var combo = this.getAggregation('combo')
var hbox = this.getAggregation('_hbox');
combo.attachEvent("selectionChange", function() {
hbox.destroyItems();
var text = this.getSelectedItems().map(function(item) {
return item.getText();
});
if (text.length > 0) {
hbox.addItem(new Text({ text: text.join(",")}))
}
})
}
});
var combo = new DropDownWithTags({
combo: new MultiComboBox({
items: [
new Item({
key: "test",
text: "test"
}),
new Item({
key: "test1",
text: "test1"
})
]
})
});
combo.placeAt("content")
});
I need to filter a Tree (search for a node by comparing a text to a node attribute).
This fiddle is exactly what I need, but seems it is not working with ExtJS 6.2.
After a day trying to find out what is wrong in my code, I've decided to simply change the framework version in the fiddle from 4.2.1 (default) to 6.2.981 classic gray and can see the code is obsolete (removing all nodes or an arbitrary amount I can't see why).
Can someone verify that code and tell me how to port it to v6.2?
EDIT:
Almost there. This code is doing the job, but stops in deep level 2, not all the tree: JSFiddle
Ext.define('TreeFilter', {
extend: 'Ext.AbstractPlugin',
alias: 'plugin.treefilter',
collapseOnClear: true, // collapse all nodes when clearing/resetting the filter
allowParentFolders: false, // allow nodes not designated as 'leaf' (and their child items) to be matched by the filter
init: function(tree) {
var me = this;
me.tree = tree;
tree.filter = Ext.Function.bind(me.filter, me);
tree.clearFilter = Ext.Function.bind(me.clearFilter, me);
},
filter: function(value, property, re) {
var me = this,
tree = me.tree,
matches = [], // array of nodes matching the search criteria
root = tree.getRootNode(), // root node of the tree
property = property || 'text', // property is optional - will be set to the 'text' propert of the treeStore record by default
re = re || new RegExp(value, "ig"), // the regExp could be modified to allow for case-sensitive, starts with, etc.
visibleNodes = [], // array of nodes matching the search criteria + each parent non-leaf node up to root
viewNode;
if (Ext.isEmpty(value)) { // if the search field is empty
me.clearFilter();
return;
}
tree.expandAll(); // expand all nodes for the the following iterative routines
// iterate over all nodes in the tree in order to evalute them against the search criteria
root.cascadeBy(function(node) {
if (node.get(property).match(re)) { // if the node matches the search criteria and is a leaf (could be modified to searh non-leaf nodes)
matches.push(node) // add the node to the matches array
}
});
if (me.allowParentFolders === false) { // if me.allowParentFolders is false (default) then remove any non-leaf nodes from the regex match
Ext.each(matches, function(match) {
if (!match.isLeaf()) {
Ext.Array.remove(matches, match);
}
});
}
Ext.each(matches, function(item, i, arr) { // loop through all matching leaf nodes
root.cascadeBy(function(node) { // find each parent node containing the node from the matches array
if (node.contains(item) == true) {
visibleNodes.push(node) // if it's an ancestor of the evaluated node add it to the visibleNodes array
}
});
if (me.allowParentFolders === true && !item.isLeaf()) { // if me.allowParentFolders is true and the item is a non-leaf item
item.cascadeBy(function(node) { // iterate over its children and set them as visible
visibleNodes.push(node)
});
}
visibleNodes.push(item) // also add the evaluated node itself to the visibleNodes array
});
root.cascadeBy(function(node) { // finally loop to hide/show each node
viewNode = Ext.fly(tree.getView().getNode(node)); // get the dom element assocaited with each node
if (viewNode) { // the first one is undefined ? escape it with a conditional
viewNode.setVisibilityMode(Ext.Element.DISPLAY); // set the visibility mode of the dom node to display (vs offsets)
viewNode.setVisible(Ext.Array.contains(visibleNodes, node));
}
});
}
,
clearFilter: function() {
var me = this,
tree = this.tree,

} // collapse the tree nodes

I want to send the result re.category to app.userdetails page.kindly anyone help me.
using $stateParams
$state.go('app.userdetails',{'category': res.category});
I try to build an input field for quantities with plus and minus buttons. More like to understand how composite controls are working. I found this documentation.
I thought I could use the new control like this:
new ex.perimental.Input({
width: "14em",
editable: true,
input: new sap.m.Input({
width: "8em",
value: {
path: "model>Quantity",
type: new sap.ui.model.type.Integer({}, {
minimum:0
})
},
description: "{model>Unit}"
}),
})
The control code looks like this:
sap.ui.define([
"sap/ui/core/Control",
"sap/m/Button",
"sap/m/Input"
], function(Control, Button, Input) {
"use strict";
return Control.extend("ex.perimental.Input", {
metadata: {
properties: {
width: {
type: "string",
defaultValue: "14em",
},
editable: {
type: "boolean",
defaultValue: false,
},
},
aggregations: {
_increaseButton: {
type: "sap.m.Button",
multiple: false,
visibility: "hidden",
},
_decreaseButton: {
type: "sap.m.Button",
multiple: false,
visibility: "hidden",
},
input: { type: "sap.m.Input", multiple: false },
_hBox: { type: "sap.m.HBox", multiple: false, visibility: "hidden" },
},
events: {
increase: {},
decrease: {},
},
},
_onDecrease: function(oEvent) {
var oResourceBundle = this.getModel("i18n").getResourceBundle();
var oldValue = this.getAggregation("input").getValue();
var newValue = 0;
if (!isNaN(Number(oldValue))) {
newValue = Number(oldValue) - 1;
}
oInput.setValue(newValue);
this.fireEvent("decrease", {
oldValue: oldValue,
newValue: newValue,
});
},
_onIncrease: function(oEvent) {
var oResourceBundle = this.getModel("i18n").getResourceBundle();
var oldValue = this.getAggregation("input").getValue();
var newValue = 0;
if (!isNaN(Number(oldValue))) {
newValue = Number(oldValue) + 1;
}
oInput.setValue(newValue);
this.fireEvent("increase", {
oldValue: oldValue,
newValue: newValue,
});
},
init: function() {
this.setAggregation(
"_decreaseButton",
new Button({
icon: "sap-icon://sys-minus",
press: this._onDecrease.bind(this),
})
);
this.setAggregation(
"_increaseButton",
new Button({
icon: "sap-icon://sys-add",
press: this._onIncrease.bind(this),
})
);
this.setAggregation(
"_hBox",
new sap.m.HBox({
items: [
this.getAggregation("_decreaseButton"),
this.getAggregation("_increaseButton"),
],
})
);
},
setEditable: function(sValue) {
debugger;
// aggregations will be null now
// I assume because they are reused in the HBox control
// this.getAggregation("_increaseButton").setEditable(sValue);
// this.getAggregation("_decreaseButton").setEditable(sValue);
// this.getAggregation("input").setEditable(sValue);
},
setWidth: function(sValue) {
this.getAggregation("_hBox").setWidth(sValue);
},
setInput: function(oInput) {
this.setAggregation("input", oInput);
var oHBox = this.getAggregation("_hBox");
oHBox.insertItem(oInput, 1);
},
renderer: function(oRenderManager, oControl) {
oRenderManager.write("<div");
oRenderManager.writeControlData(oControl);
oRenderManager.addClass("myStyle");
oRenderManager.writeClasses();
oRenderManager.write(">");
oRenderManager.renderControl(oControl.getAggregation("_hBox"));
oRenderManager.write("</div>");
}
});
});
It will be rendered but the setEditable is not working.
The buttons (used inside the HBox control again) are not reachable via getAggregation. Also the input field (set from outside) can't be accessed.
Not sure how to do it right. Anyone an idea?
Edit2
This is the latest version but still not working.
I am asking me how to put the externally defined input control into the right place inside the inner Hbox control and be able to access this control in methods like setEditable?
sap.ui.define([
"sap/ui/core/Control",
"sap/m/Button",
"sap/m/Input"
], function(Control, Button, Input) {
"use strict";
return Control.extend("ex.perimental.Input", {
metadata: {
properties: {
width: {
type: "string",
defaultValue: "14em",
},
editable: {
type: "boolean",
defaultValue: false,
},
},
aggregations: {
_hBox: { type: "sap.m.HBox", multiple: false, visibility: "hidden" },
},
associations: {
input: { type: "sap.m.Input", multiple: false, singularName: "input" },
},
events: {
increase: {},
decrease: {},
},
},
_onDecrease: function(oEvent) {
var oResourceBundle = this.getModel("i18n").getResourceBundle();
var oldValue = this._input.getValue();
var newValue = 0;
if (!isNaN(Number(oldValue))) {
newValue = Number(oldValue) - 1;
}
this._input.setValue(newValue);
this.fireEvent("decrease", {
oldValue: oldValue,
newValue: newValue,
});
},
_onIncrease: function(oEvent) {
var oResourceBundle = this.getModel("i18n").getResourceBundle();
var oldValue = this._input.getValue();
var newValue = 0;
if (!isNaN(Number(oldValue))) {
newValue = Number(oldValue) + 1;
}
this._input.setValue(newValue);
this.fireEvent("increase", {
oldValue: oldValue,
newValue: newValue,
});
},
init: function() {
this._decreaseButton = new Button({
icon: "sap-icon://sys-minus",
press: this._onDecrease.bind(this),
});
this._increaseButton = new Button({
icon: "sap-icon://sys-add",
press: this._onIncrease.bind(this),
});
this.setAggregation(
"_hBox",
new sap.m.HBox({
items: [
this._decreaseButton,
this.getAssociation("input"),
this._increaseButton,
],
})
);
},
setEditable: function(sValue) {
var bEditable = false;
if (sValue === true) {
bEditable = true;
}
this._decreaseButton.setEnabled(bEditable);
this._increaseButton.setEnabled(bEditable);
// seems not always working
this._input.setEditable(bEditable);
},
setWidth: function(sValue) {
this.getAggregation("_hBox").setWidth(sValue);
},
setInput: function(oInput) {
this.setAssociation("input", oInput);
this._input = oInput;
var oHBox = this.getAggregation("_hBox");
oHBox.insertItem(oInput, 1);
},
renderer: function(oRenderManager, oControl) {
oRenderManager.write("<div");
oRenderManager.writeControlData(oControl);
oRenderManager.addClass("myStyle");
oRenderManager.writeClasses();
oRenderManager.write(">");
oRenderManager.renderControl(oControl.getAggregation("_hBox"));
oRenderManager.write("</div>");
}
});
});
I still have problems with the association handling (updated code) I guess handling the association should be done different? Sometimes the input field is still null.
a control can only be aggregated by one control at a time.
This is the difference between associations (control may be at multiple at the same time) and aggregations.
What you can do in your init is:
this._decreaseButton = new Button (...)
Basically you only need one aggregation for your HBox.
If your buttons are then aggregated by the HBox they will know the models of the parent and also be destroyed.
The only thing you need to check if your Root control is a Ancestor of the created controls (use myControl.getParent()).

I have a function :
var my_form = function() {
return {
layout:'form',
items: [
{
xtype:'textfield',
fieldLabel: "Name",
maxLength: 255
}
]
};
}
I want to render it dynamically. This doesn't work :
var t = Ext.DomHelper.createTemplate(my_form()).compile();
Ext.DomHelper.insertBefore('my_div', t);
How to do this ?
Thanks :)
I found out it can work this way: first create a div via DomHelper, then create the FormPanel using the "renderTo" config option.
Ext.onReady(function(){
var formdiv = Ext.DomHelper.insertBefore('my_div', {tag: 'div', id: 'form_div' } );
var my_form = function() {
return {
layout:'form',
renderTo:'form_div',
items: [
{
xtype:'textfield',
fieldLabel: "Name",
maxLength: 255
}
]
};
}
var t = new Ext.FormPanel(my_form());
});
