Removed widget remains on parent

it fixes the issue Move the child inside the parent's showeEvent. You can use a bool flag to do it only when the parent is shown for the first time.

void Parent::showEvent(QShowEvent *)
{
    if(_first_show)
    {
        _first_show = false;
        _child->move(this->rect().center() - _child->rect().center());
    }
}

To fix this issue Hey all I'm relatively new to coding, only few months into my games development course, and I'm trying to figure it all out still, anyways I'm making a small bullet hell style space shooter for my course and I'm having issues with despawning my boss enemy. The players bullets collide with the sprite and the sprite is removed however the hitbox of the boss still remains intact and the player can keep shooting it to gain points. , It appears you are removing the sprite with

BaseClass.allSprites.remove(boss)

if not bossdead    
    bulletGroup = pygame.sprite.spritecollide(boss, player.bulletGroup, False)
    count = len(bulletGroup) #Check if any colliding
    #Draw enemy
    if count > 0: # Begin Removal from sprite groups
        player.removeBulletGroup(bulletGroup)
        BaseClass.allSprites.remove(boss)
        #boss.kill()
        bossdead = True
        score += 100

To fix the issue you can do You need to pass a key to your children. Or else the renderer won't be able to know which SlideTransition got removed, and use the index.
But in your case there's a much easier solution. Use Dismissible

With these it helps I have a radiobutton that highlights the corresponding LabelFrame. , I've found a way to get what I want.

    def colorLabels(self):
        if self.radioBtnVar.get() == 'PCG':
            for child in self.LabelFrame1.winfo_children():
                child.config(state='enabled')
            self.LabelFrame1.config(highlightbackground='cyan', highlightcolor='cyan', highlightthickness=2)

            for child in self.LabelFrame2.winfo_children():
                child.config(state='disabled')
            self.LabelFrame2.config(highlightthickness=0)

        elif self.radioBtnVar.get() == 'UG':
            for child in self.LabelFrame2.winfo_children():
                child.config(state='enabled')
            self.LabelFrame2.config(highlightbackground='cyan', highlightcolor='cyan', highlightthickness=2)

            for child in self.LabelFrame1.winfo_children():
                child.config(state='disabled')
            self.LabelFrame1.config(highlightthickness=0)

help you fix your problem Your filter command is git filter-branch … HEAD but your list command is git rev-list … --all. That is, you filtered one branch (master) but searched the file in all branches.
Filter all other branches too:

git filter-branch --index-filter "git rm -r -rf --cached --ignore-unmatched file_123.xlsx" -- --all
