I am opening a pop up within a application and problem is that this popup window is not opening correctly when i want to open popup at the end of the application that means popup height decreases and some data truncated in popup window .I am using canvas for pop up.
You can position the popup using Point Object.Set the titlewindow's width and height to fit the contents.
var titleWin:FileUpload=PopUpManager.createPopUp(this, PopupName, true) as FileUpload;
var point:Point=new Point(0, 0);
point=this.parentDocument.parent.localToGlobal(point);
titleWin.x=point.x + 100;
titleWin.y=point.y + 100;
titleWin.width=500;
titleWin.height=400;
Refer this link to read about Point object.
You would use the PopUpManager.centerPopUp() function.

Why when creating a button with a script in the function _ready, these buttons cannot be resized. (And position)
var pos
var siz
var yBut = 150
var but
func _ready():
siz = get_viewport().get_visible_rect().size
pos = get_viewport().get_visible_rect().position
but = Button.new()
$sc/vb.add_child(but, true)
but.rect_position = pos/2
but.rect_size = Vector2(siz.x, 150)
ps. The buttons are placed in a ScrollContainer in which the vBoxContainer.
Container controls will auto resize and position children controls. Try using the Button's size flags to suggest it's size.
You can also compose ui with multiple levels of other Container controls such as V and HBoxContainer using size flags. This will give you finer control over the whole look of the ui. This will also make it easier to add controls later that will adaptively resize.
You can also set rect_min_size and the Container will not resize it any smaller than min size. However, that may break dynamic layout.
Hope this helps!
I followed the tutorial on creating a popup for an add-on in Firefox, and it worked great.
The issue I'm having now is that the popup it creates doesn't change size to fit the content I add to it. Instead, it adds scroll bars.
So, how do I change the size of a Firefox Add-on SDK popup to show all content?
You do have to deal with that yourself.
If you already know the desired size when creating the panel, you can pass the height and width as properties of the object to the Panel() constructor.
After a panel is created, its size can be changed by setting the height and width properties on it.
height and width values are numbers in pixels.
See https://developer.mozilla.org/en-US/Add-ons/SDK/High-Level_APIs/panel for a full documentation of how to use panels.
Though the tutorial and docs never say it, the height and width of a panel always defaults to the same small size.
To change it you can use the height and width parameters for the panel class.
If you want it to change automatically you can use this code:
//index.js
var panel = require("sdk/panel").Panel({
height: 200, //choose your default
width: 200,
contentURL: data.url("popup.html"),
contentScriptFile: data.url("auto_resize_popup.js")
});
panel.port.on("resize", function (size) {
console.log(size);
panel.resize(size.width, size.height);
});
...
//auto_resize_popup.js
var content = document.body;
var size = {};
size.width = content.offsetWidth + 2; //2 extra pixels get rid of scroll bars
size.height = content.offsetHeight + 2;
self.port.emit("resize", size);
Somehow I can't manage to get an imageview to be on top of a window. This is my code:
var win = Titanium.UI.createWindow();
var startupView = Titanium.UI.createImageView({
image: 'iphone/Default.png',
opacity:1,
zIndex:20
});
var w = Titanium.UI.createWindow({
title:'Menu',
url:'menu.js',
zIndex: 1,
backgroundImage:'ui/bg.gif'
});
w.open();
win.add(startupView);
win.open();
Basically, I am loading something in the background, and upon finish I am fading out the "startupView". When faded out, I want to have the "w" window to be open underneath it.. What am I missing here?
dont add the startupView...
just open the window... then open the startup view... then fade the startupView out when the window is finished loading
The Flex Canvas container is limited to 10,000x10,000 pixels. Yet, I've seen Flex apps that are scrolling way more than 10,000 pixels. Any idea how this can be done?
The content I want to scroll is in pieces already, but I need to add those pieces to something that can scroll vertically more than 10,000 pixels.
Depending on what you actually want to display you may be able to split your content into tiles. This is how Google Maps works, every time the map is moved the program determines which tiles are visible on the screen and loads them in. Any markers or overlays that are on the map are notified that the map has moved and determine where their new location is. If their location is off the screen they can be removed from the canvas. For example, the width of all the tiles at zoom level 20 on Google Maps is (256 pixels * 2^20) which equals 268,435,456 total pixels.
Essentially you just need to create a special Sprite that keeps track of the actual x,y location it is supposed to be positioned at. Any time the container moves you simply iterate through all of the child objects and determine where to put them.
function onCanvasScroll() {
//determine the top left coordinates of the canvas
//you will figure out how to do this depending on how the scrolling window
//is implemented
var canvas_scroll_x;
var canvas_scroll_y;
//create a bounding box for the canvas
var view_bounds = new Rectangle(canvas_scroll_x, canvas_scroll_y, canvas.width, canvas.height);
for (child in canvas) {
var x = child.actual_x - view_bounds.x;
var y = child.actual_y - view_bounds.y;
var childBounds = new Rectangle(x, y, child.width, child.height);
//determine if the component is visible on screen
if (view_bounds.intersects(child_bounds)) {
child.visible = true;
child.x = x;
child.y = y;
}
else {
child.visible = false;
}
}
}
So if you have a canvas that is positioned at (100, 20000), a sprite that is positioned at (300, 20100), and a window that is (640,408), you would place it at (200, 100) and it would be visible on the screen.
Instead of just setting visible to true or false a better approach would be to remove the items from the canvas entirely when they are not within the bounds of the view.
I have a several chart components that I have created in Flex. Basically I have set up a special UI that allows the user to select which of these charts they want to print. When they press the print button each of the selected charts is created dynamically then added to a container. Then I send this container off to FlexPrintJob.
i.e.
private function prePrint():void
{
var printSelection:Box = new Box();
printSelection.percentHeight = 100;
printSelection.percentWidth = 100;
printSelection.visible = true;
if (this.chkMyChart1.selected)
{
var rptMyChart1:Chart1Panel = new Chart1Panel();
rptMyChart1.percentHeight = 100;
rptMyChart1.percentWidth = 100;
rptMyChart1.visible = true;
printSelection.addChild(rptMyChart1);
}
print(printSelection);
}
private function print(container:Box):void
{
var job:FlexPrintJob;
job = new FlexPrintJob();
if (job.start()) {
job.addObject(container, FlexPrintJobScaleType.MATCH_WIDTH);
job.send();
}
}
This code works fine if the chart is actually displayed somewhere on the page but adding it dynamically as shown above does not. The print dialog will appear but nothing happens when I press OK.
So I really have two questions:
Is it possible to print flex components/charts when they are not visible on the screen?
If so, how do I do it / what am I doing wrong?
UPDATE:
Well, at least one thing wrong is my use of the percentages in the width and height. Using percentages doesn't really make sense when the Box is not contained in another object. Changing the height and width to fixed values actually allows the printing to progress and solves my initial problem.
printSelection.height = 100;
printSelection.width = 100;
But a new problem arises in that instead of seeing my chart, I see a black box instead. I have previously resolved this issue by setting the background colour of the chart to #FFFFFF but this doesn't seem to be working this time.
UPDATE 2:
I have seen some examples on the adobe site that add the container to the application but don't include it in the layout. This looks like the way to go.
i.e.
printSelection.includeInLayout = false;
addChild(printSelection);
Your component has to be on the stage in order to draw its contents, so you should try something like this:
printSelection.visible = false;
application.addChild(printSelection);
printSelection.width = ..;
printSelection.height = ...;
...
then do the printing
i'm not completely sure, but in one of my application I have to print out a complete Tab Navigator and the only method i have found to print it is to automatically scroll the tabnavigator tab in order to show the component on screen when i add them to the printjob.
In this way they are all printed. Before i created the tabnaviagotr scrolling the print (to PDF) result was a file with all the pages of the tab but only the one visible on screen really printed.
