QUESTION

Failed linking file resources when using Motion Layout KeyPosition

Asked 2019-Oct-19 at 04:01

I am getting

"Failed linking file resources"

with

"error: attribute type (aka com.testapp.client:type) not found"

When using the new MotionLayout, specifically when adding a KeyPosition element to the scene file.

My scene file for reference:

Nevermind :)

Attribute "type" on KeyPosition element has been changed in Alpha 2 to be "keyPositionType"

QUESTION

Why does custom cursor image show up incorrect?

Asked 2017-Nov-27 at 19:52

Background

I have written a function, which creates a custom cursor, based on the bitmap associated with a given Device Context. I use this to create drag-and-drop cursors that appear as "tear-offs" - a bit like they are used in "Trello".

I've been using the function for a while without problems, but when I use it with a new tree component I'm working on it started creating partially blank cursors.

I have verified that the problem occur both in Delphi 2010 and Delphi Berlin, and I have also verified that it's broken both in Windows 7 and Windows 10.

Here is a photo that shows what the cursor should look like (Sorry - couldn't find a quick way to screen-grab a cursor):

And here is what it looks like when it's partially blank (well, it's more than partially blank - it's practically invisible):

Troubleshooting

After troubleshooting I've found, that if a PNG-image is written to the bitmap associated with the DC before a call to GetDragCursor, the cursor is messed up.

Here is the simplest code I can think of that demonstrate the problem:

A form with two TPaintBox components: MyPaintBoxWorks and MyPaintBoxBroken.

When you click on MyPaintBoxWorks, you get the expected cursor.
When you click on MyPaintBoxBroken you just get the png-image.

In the name of making it easy to read (I hope), I've excluded all error- and resource-handling. This has no impact on the problem. In order for it to work, you need to have access to a Png-image. Any png-image will do. Then update the code to load your image instead.

I was able to make it work with GDI+.
Seems like the Delphi png draw does not paint well on a transparent 32bit Bitmap. (* see EDIT)

Your GetDragCursor worked well for me.

I used a TPaintBox with height of 16. and loaded a PNG with size of 32x32. and used a 32bit off-screen bitmap to create the cursor.

AttributeError: GameObject instance has no attribute - PyGame

Asked 2017-Oct-21 at 18:52

class GameObject:
def __init__(self, x=0, y=0, width=0, high=0, imName="", imAlpha=False ):
    self.x = x # on screen
    self.y = y
    self.width = width
    self.high = high
    self.imageName = imName
    self.imageAlpha = imAlpha
    self.image

def loadImage(self):
    self.image = pygame.image.load(self.imageName)
    self.image = pygame.transform.scale(self.image, (self.width, self.high))
    if self.imageAlpha == True:
        self.image = self.image.convert_alpha() 
    else:
        self.image = self.image.convert()


pygame.init()
player = GameObject(px0, py0, width, high, "player.png", True)
player.loadImage()

In the last line of __init__, which is called when you define player, you are attempting to access self.image, which does not exist.

QUESTION

Slow App Store Download Times

Asked 2017-Mar-13 at 08:19

I'm a developer and I want to speed up the time it takes for a US user to download my app. I'm looking into image compression like ImageOptim and ImageAlpha to reduce the overall file size. But it just seems like App Store downloads are very slow and some users are probably cancelling or forgetting about the download.

This is a long shot but my question is: Is there a way to self-host and use a Content Delivery Network (CDN) to speed up the download?

...

ANSWER

Answered 2017-Mar-13 at 08:19

No, you can't host your app on a CDN and make it available on the App Store. Just make sure your app binary is as small as possible, on everything else you have basically zero influence.

You can use ImageAlpha like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
