if(anchorWidthFlag)
{
popUp.popUpWidthMatchesAnchorWidth = false;
popUp.explicitWidth = anchorWidth;
}
here AnchorWidthFlag = true and anchorWidth = 350;
i tried this way
1) popUpWidthMatchesAnchorWidth = false
2) explicitWidth = anchorWidth //350
but not get appropriate output.
I want to set minWidth and maxWidth to anchor popup, can anyone help me?
Try to set popUpWidthMatchesAnchorWidth to false and set minWidth and maxWidth on dropDown group. If I understood what you want, it would work.
Setting minWidth/maxWidth on popupAnchor woudn't make any effect due to the fact, that popup is not a child of popupAnchor. So standard flex measuring steps wouldn't work here. Though popup doesn't know parent minWidth/maxWidth. If you open the source code of PopUpAnchor you will see that if popUpWidthMatchesAnchorWidth is true the size of popup is set to explicit size of the popupAnchor, but there is no code about minWidth/maxWidth. If you really need to set these sizes on PopUpAnchor you would extend PopUpAnchor class and implement this functionality.

I want to change the color of a state of a cell during resize of the cell.
To achieve this, I have added the following code to mxVertexHandler.prototype.updateLivePreview:
mxVertexHandler.prototype.updateLivePreview = function (me) {
...
this.state.x = this.bounds.x;
this.state.y = this.bounds.y;
this.state.origin = new mxPoint(this.state.x / scale - tr.x, this.state.y / scale - tr.y);
this.state.width = this.bounds.width;
this.state.height = this.bounds.height;
...
this.state.shape.fill = "#CCCCCC";
this.state.shape.fillOpacity = 30;
...
}
What happens is that this code changes the opacity of the cell while resized, but does not change the fill color.
How can I cange the fill color too?
Thanks,

No, that does not work either.
BTW, I thought that temporal changes, e.g. during a resize, should go via the state.
I do not understand why fillOpacity (and other properties) works, and fill not. It seems that the fill is overwritten somewhere else (e.g. after calling updateLivePreview), but I can not figure out where.
I need to know the width and height of a SVG element? Im trying to use the following:
$('g#myGroup').height()
...but the result is always zero?
svg <g> elements don't have explicit height and width attributes, they auto size to whatever they contain. You can get their actual height/width by calling getBBox on the element though:
var height = document.getElementById("myGroup").getBBox().height;
If you're really into jquery you could write it as
$('g#myGroup').get(0).getBBox().height;
according to Reed Spool
I wasn't able to get any of the answers above to work, but did come across this solution for finding it with d3:
var height = d3.select('#myGroup').select('svg').node().getBBox().height;
var width = d3.select('#myGroup').select('svg').node().getBBox().width;
getBBox() here will find the actual width and height of the group element. Easy as that.
Based on the above answer, you can create jQuery functions .widthSVG() and .heightSVG()
/*
* .widthSVG(className)
* Get the current computed width for the first element in the set of matched SVG elements.
*/
$.fn.widthSVG = function(){
return ($(this).get(0)) ? $(this).get(0).getBBox().width : null;
};
/*
* .heightSVG(className)
* Get the current computed height for the first element in the set of matched SVG elements.
*/
$.fn.heightSVG = function(){
return ($(this).get(0)) ? $(this).get(0).getBBox().height : null;
};
I'm trying to wordwrap a textfield inside a button, however after i set wordwrap to true some unexpected behavior happened.
Button.width = 390;
Button.textField.autoSize = TextFieldAutoSize.LEFT;
Button.textField.border = true;
Button.textField.wordwrap = true;
Button.textField.multiline = true;
Button.textField.width = textButton.width - 10;
Button.textField.x = 5;
Button.height = 60;
This is what happens:
When I'm outputting the Button.textField.textWidth, it seems shown a value that so much less than Button or Button.textField.width. I just want to make the word break after textwidth meets the textField.width maximum value. Is there anything that I can do to change this behavior? …since I can't change the value of Button.textField.textWidth (read-only).
Comment out the Button.textField.autoSize setting. This is probably what is throwing everything off.
You're setting the text field's width to match the size of the button when you set width = textButton.width - 10, but you're also telling it to automatically resize the textField to match the size of the actual text when you set the autoSize setting. So it's not going to fit the button the way you want it to.
I have been trying to get the height of an image dynamically while adjusting the browser window.
I used console.log() to get the value to check if my results are correct, and somehow the result is always 0! What am I doing wrong?
$(function(){
var ScreenHeight = $(window).height();
var ImageHeight = $('#bkgImages').height();
var ImageMove = (ScreenHeight-ImageHeight)/2
$('#wrapper').slideDown(500);
$('#bkgScreen').animate({opacity: .5}, 700);
$('#bkgImages').css({top: "-" + ImageMove + "px"});
console.log(ImageHeight);
});
I manage to get the window height result working but not the div element height. The other issue is this calculates the result only once per session, where as I need to function to run every-time a user adjusts the browser window size. How do I go about doing that?
I think it depends on the css property of the div, and you may refer to answer here https://stackoverflow.com/a/10656669/693110.
In short, you need to specify the div to have display: inline-block; property.
What is the default height of a scroll bar(Horizontal)?
I couldn't find the document online.
UPDATED: Can we write a javascript function to get it? Please don't down vote it. It is hard to get it.
Thank you.
Found this here: How can I get the browser's scrollbar sizes?
function getScrollBarWidth () {
var inner = document.createElement('p');
inner.style.width = "100%";
inner.style.height = "200px";
var outer = document.createElement('div');
outer.style.position = "absolute";
outer.style.top = "0px";
outer.style.left = "0px";
outer.style.visibility = "hidden";
outer.style.width = "200px";
outer.style.height = "150px";
outer.style.overflow = "hidden";
outer.appendChild (inner);
document.body.appendChild (outer);
var w1 = inner.offsetWidth;
outer.style.overflow = 'scroll';
var w2 = inner.offsetWidth;
if (w1 == w2) w2 = outer.clientWidth;
document.body.removeChild (outer);
return (w1 - w2);
};
alert( getScrollBarWidth () );
That's going to depend on the clients screen resolution and browser. If you explain why your asking then I might be able to give a better answer.
Whatever the user's computer is set to. There is no hard-and-fast rule on this. For example, on my Ubuntu machine, the default scroll bar size is 0 - instead of a conventional scrollbar, it has a scroll line with arrows that appear when the mouse moves near it, and it takes no space on the document. However, on my Windows installation, the scrollbar size is 14 pixels, but I could set it from anything between about 8 and over 500...
Interesting question. My thought is: when a property you are interested in is not readily available, test.
One DOM property I can think of that would be affected by the scrollbar height is the clientHeight of the body (or whatever box has the scrollbar) if you set it to 100%. This is maybe a dumb approach, and not sure how useful it really is, but check it out:
get clientHeight before
expand width of an internal element, wide enough to cause a scrollbar
get clientHeight after
subtract
I made a fiddle of this. Like I said, not sure how useful this approach could be in real life, but maybe it's a start on something.
