Choosing optimal layouts for resizeable windows in qooxdoo - layout

I am trying to understand Qooxdoo.
So, window, using "VBox" layout is working, toolbar too, but the table component
working wrong.
qx.Class.define("tiny.MainWindow",
{
extend : qx.ui.window.Window,
construct : function()
{
this.base(arguments, "tiny")
this.setContentPadding(0);
this.setWidth(400);
this.setHeight(300);
var layout = new qx.ui.layout.VBox();
this.setLayout(layout);
this.setShowMinimize(false);
this.setAllowClose(false);
this.setContentPadding(0);
this.open();
// toolbar and buttons is hidden
// because only table works wrong
var tableModel = new qx.ui.table.model.Simple();
tableModel.setColumns(["ID"]);
tableModel.setData([[0],[1],[2],[3]]);
var table = new qx.ui.table.Table(tableModel);
this.add(table, {row: 1, column: 0, colSpan: 10});
this.add(table, {flex: 1});
}
});
var tiny_window = new tiny.MainWindow();
tiny_window.open();
tiny_window.moveTo(100, 100);
I've got this output:
"The property 'row' is not supported by the VBox layout!"
Table is shown correctly, but vertical resizing isn't changing
table vertical size.
So, what layout types I must use with table component, toolbar?
P.S.: I am already tried "Dock" layout. Here, error is similar: "The property 'row' is not supported by the Dock layout!: The value 'row' must have any of the values defined in the array 'flex,edge,height,width'". Maybe I need other way to define the table size?

just drop the line
this.add(table, {row: 1, column: 0, colSpan: 10});
it is only valid for a grid layout
The optimal layout in your case with only one item in the window would probably be
qx.ui.layout.Grow()

How to find bit length of text with specific font and font size

I'm developing NativeScript JavaScript code to create dynamic text marker for maps. I have the code working that creates a marker for a specific string. My next step is to take any given string, determine its height and width in bits, and create the marker sized to contain the text.
My problem is finding the size of the text, given the text string itself, the font size, and the font family.
It looks like getMeasuredWidth could work, except that the string must already be loaded on a page before that function will return a value. In my case, I simply need to compute the size; the text won't otherwise appear as such on a page (the text in the marker becomes an image).
Is there a way to do this?
var bmp = BitmapFactory.create(200);
bmp.dispose(function (b) {
try {
b.drawRect(
"100,34", // size
'0,0', // upper-left coordinate
KnownColors.Black, // border color
KnownColors.Cornsilk // fill color
);
b.writeText(
"Parking",
"2,25",
{ color: KnownColors.Black, size: 8, name: 'fontawesome-webfont', });
...
In the code above, the width of "100" of the bounding rectangle actually represents the bit width of "Parking" with a small amount of padding. What I want to does calculate the rectangle's height and width and not hard-code it.
Try this, finding label size without adding it to Page upon button click
export function onFindButtonTap(args: EventData) {
const button = <any>args.object;
const label = new Label();
label.text = "Hello, found my size?"
label.fontSize = 20;
(<any>label)._setupAsRootView(button._context);
label.onLoaded();
label.measure(0, 0);
console.log(`Width : ${label.getMeasuredWidth()} x Height : ${label.getMeasuredHeight()}`);
}

Note: I didn't get a chance to test it with iOS yet, let me know if you hit any issues.

Setting LayoutParams but its not working android

Trying to create a linear layout programmatically and setting its width and height by layout params. But it seems layout params isn't working.
this is the code:
// CREATING A NEW LINEAR LAYOUT PROGRAMMATICALLY
LinearLayout linearLayout = new LinearLayout(getActivity());
ViewGroup.LayoutParams layoutParams = new
ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.WRAP_CONTENT);
linearLayout.setLayoutParams(layoutParams);
linearLayout.setOrientation(LinearLayout.HORIZONTAL);
// CREATING CHILDDRENS (TEXT VIEWS)
TextView name = new TextView(getContext(), null, 0, R.style.item_layout_style);
name.setText("Pine");
TextView qty = new TextView(getContext(), null, 0, R.style.item_layout_style);
qty.setText("10");
TextView cost = new TextView(getContext(), null, 0, R.style.item_layout_style);
cost.setText("785");
TextView tCost = new TextView(getContext(), null, 0, R.style.item_layout_style);
tCost.setText("1000");
// SET TEXT VIEW TO LINEAR LAYOUT
linearLayout.addView(name);
linearLayout.addView(qty);
linearLayout.addView(cost);
linearLayout.addView(tCost);
// SET LINEAR LAYOUT TO PINE LAYOUT
LinearLayout daddy= (LinearLayout) view.findViewById(R.id.layout);
daddy.addView(linearLayout, 2);
// Return the view
return view;
I have root layout (daddy) which has many linear layouts (vertically oriented), but I need to create a linear layout programmatically and add that to "daddy". But the text views are sticked together, they aren't getting the entire space horizontally.
Do help me!
Everything is fine with the code. It is the style that I tried to give to text views, they weren't getting layout weight, width and height. How did I find this out? Well I set the linear layout's background-color to black to see if it's really not getting width and height set by LayoutParams. And I wasn't wrong! Width was set to match parent. So what I did was create a new layout param for text views and set it to them.

libgdx table lays out components only in bottom right area

I'm using a Table to add some Labels to a stage. For some reason it adds it to the bottom right corner instead of the top left. Any ideas about how I can lay out the components correctly?
int dialogWidth = 450;
int dialogHeight = 650;
Label label1 = new Label("MUSIC:", skin);
Label label2 = new Label("SOUND EFFECTS:", skin);
Label label3 = new Label("JUMP SPEED:", skin);
TextButton btn1 = new TextButton("whatever", skin);
final Dialog dialog = new Dialog("Properties", skin);
dialog.setSize(dialogWidth, dialogHeight);
dialog.setX(Helper.RESOLUTION_X_CENTER-dialogWidth/2);
dialog.setY(Helper.RESOLUTION_Y_CENTER-dialogHeight/2);
Table t = new Table();
t.setBounds(0, 0, dialogWidth, dialogHeight);
t.add(label1);
t.row();
t.add(label2);
t.add(btn1);
t.row();
t.add(label3);
dialog.add(t);
stage.addActor(dialog);
Fix 1:
Solution: Remove the following line
t.setBounds(0, 0, dialogWidth, dialogHeight);
Reason: Don't use setBounds yourself. Let the layoutmanager handle it.
Fix 2:
Solution: Replace the following line
dialog.add(t);
with
dialog.getContentTable().add(t).expand().left().top();
Reason: Dialog is itself a Table which contains 3 components viz Title, ContentTable, ButtonTable.
Your code was adding the new Table in the row of ButtonTable (last row hence at bottom) after ButtonTable (hence right).
The updated code adds it to the Content Table where it is supposed to be.
Refer to https://github.com/EsotericSoftware/tablelayout to understand reason behind
expand().left().top();
Lastly, to debug any Table related issue, consider using debug lines (explained in the same link)
Hope this helps.

Adding title text inside gauge Dojo

i need to insert a title (not a tooltip, a text on the top) inside the svg rendered by Dojo. How can i do that?
Here my Dgauge:
http://jsfiddle.net/MacroX/pZU93/1/
PD: The line
gauge.title = 'Test Report'
doesnt show the title
EDIT: The question is regarding a label at the top of the gauge, not the title attribute as I originally thought.
You can use a TextIndicator much like you did for the value label below the needle, but you can set a labelFunc property that defines a function called to set a label and displays whatever string is returned from it.
var labelText = new TextIndicator();
labelText.set('x', 73.3);
labelText.set('y', 55);
labelText.set('labelFunc', function() {return 'Test Report';});
gauge.addElement('labelText', labelText);
Here is a modified version of your fiddle with the title text in place.
Original answer remans below in case someone else needs it
Pass the title in when you create the gauge:
var gauge = new CircularLinearGauge({
title: 'Test Report'
}, dojo.byId("gauge"));
You can also use set to set it after the gauge is created:
gauge.set('title', 'Test Report'); //does work :)
The reason for this is that the gauge widget needs to set the text you give as the title on a specific element within the widget's template. gauge.title just sets the title property of the gauge widget, and the widget has no idea when or with what value that property is being set and thus is not able to make it show up as a title attribute on the gauge.
Finally i got a way to resolve this, and this is useful when you need to personalize your dgauge. Here the example:
http://jsfiddle.net/MacroX/THJqV/
What i did is basicly create a gauge, fill it with background white, and then add elements inside
var baseWidth = 400;
gauge.addElement("background", function (g) {
var auxHeight = baseWidth * objGauge.offsetHeight / objGauge.offsetWidth;
g.createRect({
width: 400, height: auxHeight
//width: 400, height: 300
}).setFill("#FFF");
});
I dont know if is the best way, but works and i didnt find something similar in other sites
And what I think is great, this support multiple chart dgauges in only one SVG
I hope this will useful to someone else

How to manage event through a fill color with highchart?

I've got two series in an Highchart graph. Both are handling event like mousemove (to show tooltip) and mouse click.
Unfortunatly one of those series is an area serie which block any event to be triggered by the other one.
Let's say I've got those series with those plot options :
plotOptions: {
series: {
cursor: 'pointer',
point: {
events: {
click: function() {
alert ('Category: '+ this.category +', value: '+ this.y);
}
}
}
}
},
series: [{
color:'red',
data: [29.9, 51.5, 16.4, 19.2, 44.0, 16.0, 35.6, 48.5, 26.4, 4.1, 9.6, 54.4]
},
{
type:'area',
data: [39.9, 75.5, 120.4, 150.2, 130.0, 120.0, 140.6, 158.5, 216.4, 194.1, 95.6, 54.4]}
]
}
as seen in this JSFiddle
I can never click or see the tooltip on the red series points.
What I could do is to change the order of the series so the red one is over the blue one.
( like this). But I've got situations where I've got several area graphs over each other like that. In this case, change the order won't help.
Is there a way I can handle events through the fill area?
Ok I found a way that suit my need : manimulating SVG element order as indicated in this topic :
SVG re-ordering z-index (Raphael optional)
I'm using this code in the redraw event of the chart :
redraw : function(){
//get a reference on the first series svg element.
var svgSeriesParent = document.querySelectorAll('.highcharts-series')[0];
//loop on all the path drawn by highchart
var pathArray = document.querySelectorAll('path');
for (var pathIndex = 0; pathIndex < pathArray.length; pathIndex++) {
var pathObj = pathArray[pathIndex];
//if attribute fill is not "none", this is an area path.
if ($(pathObj).attr('fill') !== "none") {
//move the current fill path before the first series svg element.
svgSeriesParent.insertBefore(pathObj, svgSeriesParent.firstChild);
}
}
}
See the result in this JSFiddle
Limitation :
The fill area doesn't have the same svg group anymore thus, hidding / showing the series is broken : all the fill area are considered being part of the first series. (click in the legend to see it).
In my case I don't need to hide series so I'll go on with this solution.
The svg order manipulation is not complicated that's why I would expect highchart to manage this case : add a fillZIndex parametter doesn't seem difficult and could be pretty usefull...
Only what comes to my mind is using 4 series, 2 area and 2 lines and use index.
