Setting position of a widget

tanmay2227

i tried that but the size of the widgets are not the same so it goes more down.
i want the the bottom point of the widgets to be the same and not the top .
so the bottom point of the widget should match with the bottom of the first one

p3c0

Are the two widgets of the same size ?

tanmay2227

no the first one is much smaller the width is same but the the height of the one to be positioned is much more

p3c0

Then you need to do some calculations.
Try this and see if this is what you want

@
QLabel *bottom = new QLabel(this);
bottom->setGeometry(250,250,200,50);
bottom->setStyleSheet("background-color: rgb(255,0,0)");

QLabel *top = new QLabel(this);
top->resize(200,200);
top->move(bottom->x(),bottom->y()-(top->height()-bottom->height()));
top->setStyleSheet("background-color: rgba(0,0,255,150)");
@

I have set the alpha component of the top widget so that we may see the effect.

tanmay2227

it is appearing at that position but not on top of it i want it to appear on top of the previous widget but on doing this the previous widget just changes its position and appears over or under it .

p3c0

This is because i have set the alpha component of the top widget to make it appear transparent so that we may see the bottom points of the two widgets coincide.
Change
@top->setStyleSheet("background-color: rgba(0,0,255,150)");@
to
@top->setStyleSheet("background-color: rgb(0,0,255)");@

and check if this is what you want

tanmay2227

no i meant that the transparency is not happening it first component is moving its position they appear like this

list1

list2

while i want that they appear over one another
i want the second widget to be placed over every other widget like a menu is visible over the others

Can you post you code or what you have tried? It would be hard to guess what would be the problem in your code.

Please can you include it in Code tags. Its difficult to understand like this.

Is it possible to make next window as child of first it will show your next window always placed upon the parent and according to its geometry.

tanmay2227
