This should be a relatively easy question for you veterans to answer. I would like to be able to move a window, or as the case might be, a frame generated by Graphics().

Graphics 512,256
MoveGraphics 50,50
WaitKey
MoveGraphics 100,100
WaitKey

Is there an easy way to do this ? How would you do it ?

Not sure if this is what you are after...

Graphics 800,600
Cls

DrawRect(0,0,50,50)
Local image=CreateImage(50,50,1,DYNAMICIMAGE|MASKEDIMAGE)
GrabImage(image, 0, 0)

Flip
WaitKey()
Cls

DrawImage(image, 50, 50)

Flip
WaitKey()
Cls

DrawImage(image, 100, 100)

Flip
WaitKey()

There is "SetOrigin" if you want to offset all things drawn to your graphics context.

If you want to move the entire application window - maybe MaxGUI offers something "cross platform".

Hi Chapman & Derron:

Thanks, but no. I want the entire frame to be moveable, for instance, in GFABasic it is

MoveW#(windno),x,y

Where X & Y coordinates re-position the display frame you have opened with 0,0 being the absolute top-left corner of your monitor.

Yeah, I was thinking MaxGUI earlier could handle this; trying to avoid that route. I can look there tho, good place to go.

Currently when you use Graphics() it always centers the frame despite its size. No way to shift it to any other location - with perhaps the exception of MaxGUI.

I would use MaxGUI. If your app is windows only you can use this http://www.blitzbasic.com/Community/posts.php?topic=66129

How about this!

Thanks Chapman and Nurgle. Nurgle, your sample code is perfect. Now I just need to set down to look at it proper.

Curiously SetWindowPos() is a command internal to BlitzMAX, not requiring any additional library or MOD loading. Yet, it does not appear in the standard command set.

In any case, well done - exactly the solution I was looking for !

Bonus, it appears you have created a nice and flawless borderless window - also without requiring usage of external MODs and achieved in no more than 4-lines of code.

Outstanding ! :D

Nurgle, do you have a website showing other BlitzMAX source codes you have done for other applications I might be able to learn from ?

And/or is there a unique HELP file for BlitzMAX that lists these 'non-listed' commands and functions ?

Hi,

those are Windows native functions and wont work in X systems.

SetWindowPos() is a Win32 API function.

Documentation for Win32 stuff like this, can be found here : https://msdn.microsoft.com/en-us/library/windows/desktop/ms633545(v=vs.85).aspx

Hi Henri & Brucey:

* I was wondering ! I have a comprehensive help file from GFA on all windows functions. Is one reason I chose it years ago.

So - apparently all functions here:

https://msdn.microsoft.com/en-us/library/windows/desktop/ff468925%28v=vs.85%29.aspx

Can be accessed in BlitzMAX ?

Nurgle, at line # 67 you have:

MouseXSpeed() ; MouseYSpeed() 'update window position

As these are used to retrieve values, are they doing anything here ? REMMING them out the program runs the same.

I not the author of the example Zeke is.

Oh, you're right, Nurgle. In any case, that's some pretty nifty code. I thank you for showing it to me. :)

Functions are exposed through the Pub.Win32 module, although the ones listed there don't actually cover the full set available in the Win32 APIs.
