Anyone has an idea how to do BreadCrumb Trails in Flex 4?
For example something like:
Screen1 -> Screen2 -> Screen 3
Is it possible after all?
Help Pls
You generally navigate using currentState and ViewStacks.
Where ever you are just add link buttons on the screens separated by ">" and have their behaviour be the relevant state or stack change.
You could even dynamically add and remove buttons on entering the state.
It just depends how fancy you want to be.
But basically what you are asking is:
How do I make a button that goes to some place in my ui. Repeat for as many as needed.
click="currentState='TheNameOfTheState'"
click="SomeViewStackName.selectedIndex=1"
Thats all there is to it.

I recently noticed the following popup message ("6 occurrences replaced") in Qt Creator (3.4.2).
I like its style and want to use it in my own application. But how is it done? Is this a particular widget or what else? Can someone point me in the right direction.
You could create your own window with round corners like that with text in the middle paid show it when you want too make the window so it takes a parameter text and you can add different text each time and show
I've added some code as found here Big problems with MFC/WinAPI to colour tab titles the same as the reset of the dialog, which works, but unfortunately all the tabs end up with the same name. This doesn't surprise me all that much as GetCurSel() is used to grab the text to use, and only one tab can currently be selected, but I'm struggling to see how you access the correct tab index from OnDrawItem().
I've googled and had a look on MSDN but don't see how anything passed to OnDrawItem lets you know which tab is currently being drawn, rather all the examples I've seen assume you're only interested in the one currently selected. All I want to do is something along the lines of GetWindowText() on the child window and redraw with that. I'm also unsure of the parent/child/sibling relationship between the sheet, tab control and page - it depends who you listen to.
I should probably add that I'm also unsure why all the tabs are redrawn when I select one. I don't know if this is normal or something specific to this implementation (that's something I'm looking at, but like seemingly everything else in this code base it's multiply inherited several times over ...).
Cheers for any help.
Not to worry, I now realise lpDrawItemStruct->itemID holds the tab index so I can get a handle to the tab using that.
I want to create a form with iOS like transitions (in a Cocoa desktop application) between the form input. For instance, the user would input information to the form and click next to continue to input the remainder of the information. On the last form, the user would click submit. Upon clicking next, the form would have an animated transition, like on the iPhone before displaying the next set of forms. Sort of like how Turbo Tax ask a ton of questions before allowing you to submit that grouped information.
What would be the best approach to achieve this goal?
This is commonly referred to as a wizard.
You basically have two options:
Use a tabless tab view, following Apple's sample code in AnimatingTabView from http://developer.apple.com/library/mac/#samplecode/Reducer/Introduction/Intro.html
Manually swap the views in and out yourself.
There are pros and cons to both approaches. Which you choose will probably depend on your requirements. One issue with Core Animation on the desktop is lack of subpixel rendering for layer-backed views. This is mostly an issue with text display but some people find it not to be an issue.
I've needed this functionality a few times. I used this tutorial to get started.
I am a beginner so please take it easy. First some history, I am trying to modify a flash movie (not created by me) that has 4 images in it.
I have to now add 2 more images (pic5.png and pic6.jpg) to the "slideshow" as shown in the attachment, I have added the 2 images to the library. The problem I am having (as I understand, I may be incorrect) is that _root.count = 4 causes the movie to jump back to the first image after it displays the 4th one which does not display the 5th & 6th image.
My question, how do I edit the value of _root.count to 6, so that it will show all the 6 images. Additionally how do I create a hyperlink on each image.
Please can someone guide me.
Many thanks.
Looking at your screen shot, Layer 2 (which contains the slideshow movieclip) is locked. If you unlock the layer by clicking on the padlock icon you should then be able to edit the script.
To edit the script double-click on the script in the Movie Explorer panel and the Actions panel should open. You can edit the script here.
The second part of your question - how to create a hyperlink - is very broad and there are many different ways to approach it. The most elegant approach would depend on how your project was structured.
The simplest way might be to define a variable to hold the path to the current image and add another onClipEvent handler.
So in the existing onLoad you would add…
this.path_to_image = http://your-domain.com/images/your-first-big-image.jpg;
Then add the new event handler
onClipEvent(mouseUp){
getURL (this.path_to_image);
}
You would then have to update the path_to_image variable whenever the image changed.
slideshow.path_to_image = http://your-domain.com/images/your-next-big-image.jpg;
I'm making a simple Qt application. It has 4 screens/pages:
Start import
Select folder to import images to
Accept or reject each image in folder, and when no images left:
"No images left" and an OK button.
I can't figure out the best way to implement this. I started off with a QWidget, but this quickly got unmanageable.
Is a QWizard too constrained?
EDIT: Part of the problem with QWizard is it seems to always have "Back" and "Next" buttons. I don't want those as options in this program, so this leads me to believe that a wizard isn't exactly what I'm after.
I'm going to disagree slightly on using a QWizard here. It would be fairly easy to do, but in this case I think it might be easier to just use a QStackedWidget and swap the widget shown based on what you want the user to be able to do. This is likely what is done inside QWizard anyway, without some of the complication for running the buttons and moving back and forth. You also might want to take a look at the state machine stuff they're looking at adding soon, since you're application could so easily be split into states.
I think a QWizardPage is your best bet.
You can disable the 'back' on a QWizardPage by using setCommitPage(True) on it.
You'll also have to override nextId for the 'variable' amount of QWizardPages you want in between step 2 and 4.
here (basic) and here are examples of QWizards.
You can make QWizardPages for your screens and add them to a QWizard. With registerField() you can register fields to communicate between pages.
EDIT:
I didn't test this, but i guess you can control the button layout of QWizard with
setButtonLayout
Create a dialog with a "Start Import" button on top. When the user clicks this:
Populate a QFormLayout :
The layout should have a checkbox and the label is the name of the picture to import. I'm not sure of your requirements, but you could also display a thumbnail of the image.
The user just checks the images he wants.
Then at the bottom have a "Save..." button. When the user clicks this, a Save As dialog appears. You save all the checked images, discard the others.
If there are no images, change the "Save..." button text to "OK", and display a QLabel with the "No images left" string. You can switch between the QLabel and QFormLayout using a QStackedWidget.
Checkout this article on QFormLayout: http://doc.trolltech.com/qq/qq25-formlayout.html
Option: Get rid of the "Start Import" button. Have the app automatically populate the QFormLayout on startup (possibly in constructor if its fast enough).
