Flex :: Change The Imagealpha For A Multi-select Drag And Drop Operation?
Dec 4, 2010
Here's the code that allows multi-select list to drag into a tree area. What I would like to do is to change the alpha of the image that gets dragged around. I've done some research but most of the discussions out there talk about how to change the dragged image. What I want to do is simply change the default alpha of the dragged item from 0.5 to say 0.2. Also this solution should be able to handle multiple select dragging.
Below is a simple example of drag and drop that I would like to modify to allow for the alpha change of the draged item.
How do can you detect and dispatch an event when a drag and drop operation ends prematurely? I need to know that the user is no longer dragging an item. Even if the dragDrop and dragComplete events do no fire. Its almost as if I need to add an event listener to the dragManager, but that's not really possible..
I have a tree control with a custom item renderer. The item renderer has different states that should be set while an item is being dragged over the item renderer. I understand from reading this post [URL] that the 'right way' to do this is to override the 'getCurrentState' method and append some text. I do that.
Now in my tree control I handle the drag over event and get a reference to the itemrenderer that is being dragged over and I set the boolean 'dragOver' property to true. Now I just need to force my itemRenderer to redraw. I can't figure that out. A workaround, is to just set the currentState of the itemRenderer.
how can I force my itemRenderer to refresh? (and I've tried calling validateNow, invalideDisplayList/Properties/Size, to no avail)
Flex 4 Combobox is extended with a Text Input that helps in getting to the item that is searched for.I have created a Check Box as an itemrenderer for this Flex 4 Combobox. I would like to Add a Select All and Select None options in the drop down of the Combobox. I know that i could accomplish by editing the dropdownfactory in case of a Flex 3 Combobox. But in Flex 4 the dropdownfactory doesnt exist.
Now I set dragEnabled="true", dropEnabled="true" and dragMoveEnabled="true" to archive the ability to reorder my Items via Drag and Drop. But as soon as I start to Drag an Item the whole Application crashes with:
It's a Submit Form (name, age, etc...)If I have 4 font types embeded (eg. Arial / Varadana / Comic Sans / Eras) how can I create a drop down list of the fonts where anyone could select - change (runtime) the FONT TYPE by clicking the name?
Obasically I have the codes I need to make my project work but the problem is when I put my drag and drop code with my swap depth on hittest code my drag code stops working heeres the codes:
I'm using Flash CS5, and was wondering if this situation is possible:
I want to drag and drop an object to a specific area (which is a picture), and then the picture will change if the object is dropped at the area of the picture.
And I have one more question. Must drag and drop an object be in movie clip? I searched for examples and almost all use movie clip, a concept I have yet to understand.
Now, I'm writing a small game. I use actionscript to load a group of soldiers.It's pretty easy. But how do I select all of the soldiers by dragging the mouse?
I am trying to do a flex drag and drop. It is very similar to this first example.url....The problem is that event.currentTarget.mouseX,mouseY is showing the position where I put the mouse down rather than the position where I had finished dragging.
we want to drag a button with a css layout from one grid to the other. On the second grid should be the same button with this layout. The grids are in different mxml files.
I'm doing an application in flex where I draw different sprites inside a canvas. Depending of the dimensions, scrollbars can be appear. I would like to move the "image" with the movement of the mouse as you can see at the Adobe Reader when you are reading a document with zoom (hand mouse icon). In this way, you dont have to touch the scrollbar.I'm start trying with drag and drop properties of the canvas, setting the position of the scrollbar according with the movement of the mouse but that is not as I expect.
I am dragging item from a datagrid and while dragging I could see all of the columns in the selected record, being getting dragged. However I only want to show one column (maybe name or id of the record)? Is there a way to achieve this? Also, could I show an icon or image instead of the record while dragging.
I am building a flex project involving drag+drop of fxg graphics. My graphic is instantiated as below: <graphics:arrow2 id="object" mouseMove="mouseMoveHandler(event);" /> I get an error: "Call to a possibly undefined method Graphic."
This works if I change my drag-object to Image and replace the 'Graphic' below with 'Image'. What should I use to be able to reference the fxg graphic in the drag-drop? My drag drop functionality is as follows private function mouseMoveHandler(event:MouseEvent):void { var dragInitiator:Graphic = Graphic(event.currentTarget); var ds:DragSource = new DragSource(); ds.addData(dragInitiator,"gph"); DragManager.doDrag(dragInitiator, ds, event); [Code] .....
I have implemented drag and drop between 2 AdvancedDataGrid, but the default behaviour from Flex displays the row data during the drag using the grid item renderer showing all 5 columns.
Instead, I would like to display an icon / image or my own custom item renderer during the drag and drop.
How do I determine which Flex AdvancedDataGrid cell - row and column index - I've just dropped onto? calculateDropIndex seems to give me the row, but how do I get the column?
I was wondering, if I have two list boxes, and I want to drag and drop between both of them, how do I prevent the user from dragging onto the same list (thus duplicating the item? I cannot have a situation where that is the case
[code]I want a tree in this structure, having line between the nodes, also, instead of Open and Close Folders, I have added my own graphic there with label. I did by extending TreeItemRenderer Class. Now, I if iam dragging and dropping a child node ex:label5, and try i drop it above label1 here, it is getting dropped there. i.e.,it is becoming like.[code]
I'm trying to drag an item from a datagrid and drop it onto a UIComponet. Basically I just want the UIComponent to know that something has been dropped onto it and allow it to access the data of the dropped item.
I thought just listening for the drop event would do it but it seems not.
I found lots of documentation on dragging from one IList to another but nothing for this.
I have a List with an item renderer and would like to enable drag-and-drop onto the items in the list, rather than adding the data to the list. Is it possible to find the item that is being hovered over when dragging?
I'm developing an application that will randomize a list of words, and display them to the user. The user will then be able to drag the box containing each word over a Cartesian plane, and drop it anywhere they like. They will also be able to link various words together on the same plane. Once a user has completed these tasks, I want to update a database with that user's data - the coordinates of each word, as well as any parent words that may exist for each word. I started developing the application in Flex, but I'm running into problems integrating the data manipulation. It might just be me, but I find the way Flex is structured to be very counter-intuitive. I'm playing around with shifting the project over to perhaps a JQuery build. I'm proficient in neither JQuery nor Flex, however, and I'm not sure which one will be easier to pick up and develop a working prototype with.
I am trying to build a visual simple electric circuitry model. Towards thata) I am looking to build a drag & drop functionality, whereby I have items (wires, resistors, battery) that can be dragged and dropped on screen where I have a 10 x10 grid- the dropped items will take line positions on the grid based on where they fall.Should I do this using the mouseX, mouseY and connect them to grid points they fall closest to? The typical drag and drop examples I have seen, don't concern themselves with exact position in destination- which is obviously important here
When I enter with a dragged item into datagrid, a bold line appears over the active row of the datagrid (which is fine to show the active row), but the problem is that even after I drop the item into datagrid, that line remains there. It goes only if I enter with a new item (in which case a new line comes to the respective row again).
I am using custom handler for dragdrop event for this datagrid.
