SetWidth + Anchor point

[Ronkkrop]

Hey guys. This is my first attempt at an addon, and it's going pretty awesome except for this little hang up. I have a small movable frame that i want to grow to the right no matter where it is on the screen. Yes, obviously i'm a little bit anal lol, but i do have a button on the left that changes the size of the frame, and its annoying that it gets moved away from my mouse whenever i click it. So anyways, i was told elsewhere that the problem is my anchor point and that after StopMovingOrSizing() i need to re-anchor my frame somewhere left. Which is fine...however doing so results in some wierd bugs. It resizes, and grows just as it should when its anywhere to the left of the screen, and anywhere center, however when i move it to the right side of the screen, my backdrop no longer changes size at all. Also of note is that GetWidth() returns the correct value. Is there any reason for this, is there anything i can do? It moves around via:

Conveniently, getpoint(1) just before StopMovingOrSizing(), seems to have all the right info for anchoring TOPLEFT.

function GoldTracker_OnMouseDown()
    
    GoldTracker_MainFrame:StartMoving()
 
end 
 
function GoldTracker_OnMouseUp()
    local gtpoint, gtrelativeTo, gtrelativePoint, gtxOfs, gtyOfs = GoldTracker_MainFrame:GetPoint(1)
 
    GoldTracker_MainFrame:StopMovingOrSizing()
    GoldTracker_MainFrame:SetPoint(gtpoint, gtxOfs, gtyOfs)
        
end

I seem to have fixed the issue. Apparently :ClearAllPoints() needs to be called right before :SetPoint().

However, i do have another question. Is calling :GetPoint() just before :StopMovingOrSizing() and acceptable way to retrieve the TOPLEFT x and y offsets? Will this cause problems for me later on? ...and will it function the same system to system?

if i remember correctly
StopMovingOrSizing() - changes the anchor point to the nearest - so it could be TOPLEFT x,y=100,200 - if you force it to center -> the icon is to far away - as maybe really moved by user

Thank you for the advice, but i already have a good knowledge of StopMovingOrSizing(). My question is if its acceptable to get a TOPLEFT x and y offset by calling GetPoint() just before StopMovingOrSizing(). Right now, it seems to give me the correct offsets, what i'm concerned about is that it's just some wierd coincidence. So, will doing what i stated always have the same behaviour?

It's probably better to retrieve these values from frame:GetLeft() and frame:GetTop() after calling frame:StopMovingOrSizing(). I wouldn't trust anything frame:GetPoint() returns after a user has started moving a frame. It's also a better idea to stop movement before trying to get any coordinates from the frame.
