is there a easy method to create objects that you can interact with the mouse in actionscript. Something like a few lines of code ?
var sprite:Sprite = new Sprite(); // create a new sprite.
sprite.graphics.beginFill(0); // set fill color to black
sprite.graphics.drawRect(0,0,100,100); // draw a square
addChild(sprite); // add the sprite to the display list making it appear on screen.
sprite.addEventListener(MouseEvent.MOUSE_DOWN, onMouseDown); // add responders for mouse interaction.
sprite.addEventListener(MouseEvent.MOUSE_UP, onMouseUp);
function onMouseDown(event:MouseEvent):void {
// When the mouse button is released over the object, this code executes.
Sprite(event.target).startDrag(); // make the object follow the mouse.
}
function onMouseUp(event:MouseEvent):void {
// When the mouse button is pressed over the object, this code executes.
Sprite(event.target).stopDrag(); // make the object stop following the mouse.
}

I would like to activate the "swiperight" function only for the area marked in green.
I it possible to define a non-swipeable area?
There is more than one possible solution, to achieve what You asked for.
The swipe, swipeleft and swiperight are custom jQuery Mobile events. JQM is attaching to these events a custom structure which contain the start and stop coordinates of the original touch events.
First of all, if You want to handle the swipe by yourself, You need to tell this to the framework:
Skip the built-in panel swipe handler:
<div data-role="panel" id="myPanel" data-swipe-close="false">
After that, to open or close the panel, You can simply check either the coordinates of the touchstart, touchend or both (up to You to decide this).
Custom handling of the touch events:
$('body').on('swiperight', function (e) {
var startX = e.swipestart.coords[0],
stopX = e.swipestop.coords[0];
if(startX < 100) {
$('#myPanel').panel('open');
}
});
$('body').on('swipeleft', function (e) {
var startX = e.swipestart.coords[0],
stopX = e.swipestop.coords[0];
if(stopX < 100) {
$('#myPanel').panel('close');
}
});
If You want a more systematic approach, You may also check the some of the relevant panel options:
var data = $('#myPanel').data("mobile-panel"),
display = data.options.display, /* Panel Type: reveal, push, overlay */
position = data.options.position; /* Panel position: left, right */
and fine-tune the swipe actions (or whatever You want) accordingly.
I am using spreadsheetgear, and I want to place the combobox (ComponentOne) into 1 cell. I want that when the user go to this cell, this combobox will activate and show the list to user. After user chose item on the list, it will place this item into the cell value and hide the combobox.
How to do it in Spreadsheetgear.
Thanks,
Doit
I am not familiar with ComponentOne controls, so cannot really speak for that portion of your question. However, regarding a more general approach to embedding custom controls onto a SpreadsheetGear WorkbookView UI control, this is possible by sub-classing the UIManager class, which would allow you to intercept the creation of existing shapes on a worksheet and replace them with your own custom controls.
Below is a simple example that demonstrates this with the Windows Forms WorkbookView control and a sub-class of SpreadsheetGear.Windows.Forms.UIManager. This example just replaces a rectangle AutoShape with a button. You could modify it to show a ComponentOne CheckBox instead.
Note that the UIManager.CreateCustomControl(...) method gets called anytime a shape is scrolled into view / made visible on the WorkbookView. Also note that that your custom control will be disposed of every time it is scrolled out of view or otherwise made invisible. Please see the documentation for more details on this API.
Another important point about shapes and worksheets in general--shapes are not embedded inside a cell. Instead they hover over cells. So there will be no explicit "link" between a given shape and a given cell. The closest you could come to making such an association is with the IShape.TopLeftCell or BottomRightCell properties, which will provide the ranges for which this shape's respective edges reside over. The IShape interface contains a number of other API that you might find useful in your use-case. For instance, you can hide a shape by setting the IShape.Visible property to false.
using System;
using System.Windows.Forms;
using SpreadsheetGear;
using SpreadsheetGear.Shapes;
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
// Create the UIManager replacement.
new MyUIManager(workbookView1.ActiveWorkbookSet);
}
private void buttonRunSample_Click(object sender, EventArgs e)
{
// NOTE: Must acquire a workbook set lock.
workbookView1.GetLock();
try
{
// Get a reference to the active worksheet and window information.
IWorksheetWindowInfo windowInfo = workbookView1.ActiveWorksheetWindowInfo;
IWorksheet worksheet = workbookView1.ActiveWorksheet;
// Get a reference to a cell.
IRange cell = workbookView1.ActiveWorksheet.Cells["B2"];
// Add a placeholder shape to the worksheet's shape collection.
// This shape will be replaced with a custom control.
double left = windowInfo.ColumnToPoints(cell.Column) + 5;
double top = windowInfo.RowToPoints(cell.Row) + 5;
double width = 100;
double height = 30;
IShape shape = worksheet.Shapes.AddShape(AutoShapeType.Rectangle, left, top, width, height);
// Set the name of the shape for identification purposes.
shape.Name = "MyCustomControl";
}
finally
{
// NOTE: Must release the workbook set lock.
workbookView1.ReleaseLock();
}
buttonRunSample.Enabled = false;
}
// UIManager replacement class.
private class MyUIManager : SpreadsheetGear.Windows.Forms.UIManager
{
private Button _customControl;
public MyUIManager(IWorkbookSet workbookSet)
: base(workbookSet)
{
_customControl = null;
}
// Override to substitute a custom control for any existing shape in the worksheet.
// This method is called when a control is first displayed within the WorkbookView.
public override System.Windows.Forms.Control CreateCustomControl(IShape shape)
{
// If the shape name matches...
if (String.Equals(shape.Name, "MyCustomControl"))
{
// Verify that a control does not already exist.
System.Diagnostics.Debug.Assert(_customControl == null);
// Create a custom control and set various properties.
_customControl = new Button();
_customControl.Text = "My Custom Button";
// Add a Click event handler.
_customControl.Click += new EventHandler(CustomControl_Click);
// Add an event handler so that we know when the control
// has been disposed. The control will be disposed when
// it is no longer in the viewable area of the WorkbookView.
_customControl.Disposed += new EventHandler(CustomControl_Disposed);
return _customControl;
}
return base.CreateCustomControl(shape);
}
private void CustomControl_Click(object sender, EventArgs e)
{
MessageBox.Show("Custom Control was Clicked!");
}
private void CustomControl_Disposed(object sender, EventArgs e)
{
// Add any cleanup code here...
// Set the custom control reference to null.
_customControl = null;
}
}
}
Originally I was going to create a view component that was the size of half the screen and wrap it in a TouchableHighlight, but that seems messy.
Have a look at the Gesture Responder system, which can let you set a view to react to a touch:
http://facebook.github.io/react-native/docs/gesture-responder-system.html#content
Specifically if you pass your view a onStartShouldSetResponder prop which is a function that returns true. You can then also pass a onResponderGrant function as a prop which will receive an event object with the details you need.
Fixed it.
I added a wrapper <View {...this.panResponder.panHandlers}> to the element and filled in the onPanResponderGrant function:
onPanResponderGrant: ({ nativeEvent: { touches } }, { x0, y0, moveX }) =>{
// if on right side of screen
if (x0 > (Dimensions.get('window').width / 2)){
_this.nextPhoto();
}
}
I have a toolbar using TActionToolBar and TActionManager. A button has sub-buttons that are available clicking the small down arrow placed in the right of the button.
The width of the "arrow down" button is very thin and requires precise mouse control. How can I customize it?
Thank you
A solution is using the OnGetControlClass event of TActionToolBar.
Before, it is necessary to derive a class from TThemedDropDownButton and override the GetDropDownButtonWidth function:
function TThemedDropDownButtonEx.GetDropDownButtonWidth: Integer;
begin
Result := 14; // default drop down button width
end;
Then, in OnGetControlClass function:
void __fastcall TWorkAreaToolBarFrame::ActionToolBarLeftGetControlClass(TCustomActionBar *Sender,
TActionClient *AnItem, TCustomActionControlClass &ControlClass)
{
if(ControlClass == __classid(TThemedDropDownButton))
ControlClass = __classid(TThemedDropDownButtonEx);
}
In few words, in GetControlClass event, the toolbar allows you to define which button class you want to use. We use a custom class with the default width changed.
What I have currently is a very simple div that has a flexcroll scroll bar. This simple div contains some draggable itmes inside of it. My goal is to be able to drag one of the items and and move it about without the flexcroll scroll bar moving.
As it stands right now if I were to drag one of the items below the viewable area the simple div will scroll down. I would like to prevent this.
I'm using jQuery UI for the draggable items. I've already tried using the option "scroll:false" but this does not work for flexcroll.
I'm sorry I don't have any example code, I'm currently away from my work computer.
flexcroll: http://www.hesido.com/web.php?page=customscrollbar
I don't know if you have already resolved this problem. This morning, I have the same problem and I found your post. After that, I have googled a lot to find a solution without any lucky. So finally, I decided to do someting myself, I hope my idea will help you.
After read the Programming Guid, I found that in this version (2.0) of flexcroll, we could register a function for onfleXcroll whose description could be found by searching the keyword "Pseudo-event: onfleXcroll". This is to say that the method will be executed after a scroll is done. So here, what I restore the "top" style with the value before you drag an element.
Here are the code
var $assetswrapper; // This variable indicates the contentwrapper of you div.
var $assetsscrollbar; // This variable indicates the vscroller of you div.
window.onfleXcrollRun = function () { // This method will be executed as soon as the div has been rendered with the help of flexcroll
// You could find these two divs by using firebug, because the top value of these two divs will be changed when we scroll the div which use the class .flexcroll.
$assetswrapper = $('#contentwrapper');
$assetsscrollbar = $('#vscrollerbar');
}
var wrapperTopPosition = 0; // This is used to stock the top value of the wrapperContent before dragging.
var scrollbarTopPosition = 0; // This is used to stock the top value of the scrollbar before dragging.
var dragged; // This is a boolean variable which is used for indicating whether the draggable element has been dragged.
var dropped = false; // This is a boolean variable which used to say whether the draggable element has been dropped.
$('.draggable').draggable({ // you could change .draggable with any element.
start: function (event, ui) {
// Your code here.
wrapperTopPosition = $assetswrapper.position().top;
scrollbarTopPosition = $assetsscrollbar.position().top
dragged = true;
},
stop: function (event, ui) {
// Your code here.
dragged = false;
dropped = true;
}
});
$('your drag div')[0].onfleXcroll = function () { // This method will be called each time when a scroll has been done.
if (dragged) {
$assetswrapper.css('top', wrapperTopPosition);
$assetsscrollbar.css('top', scrollbarTopPosition);
} else {
// Code here is used for keeping the top position as before even though you have dragged an element out of this div for a long time.
// You could test the scrollbar without this piece of code, if you drag an element out of the div for a long time, the scrollbar will keep its position,
// but after you dropped this element and try to scroll the div, then the scrollbar will reach the end of the div. To solve this problem,
// I have introduced the method setScrollPos with the old top position plus 72. 72 here is to set the scroll increment for this scroll, I know
// this value is not fit for any size of windows, but I don't know how to get the scroll-increment automatically.
if (dropped) {
dropped = false;
$('your drag div')[0].fleXcroll.setScrollPos(false, Math.abs(wrapperTopPosition) + 72);
$('your drag div')[0].fleXcroll.setScrollPos(false, Math.abs(wrapperTopPosition) + 72);
}
}
};
I hope this could give you a help if you haven't found any solution yet.
