How to change the app resolution

[roseicollis]

Hi!

I'm making a new GUI app and I want it to show up with a especific resolution, so when in main.cpp I say w.show() it runs in 550x300. I've tried w.resize() but it just shows a little part of the screen instead of change its resolution so if I put an element like this:


QRect rec = QApplication::desktop()->screenGeometry();
int h= rec.height()/8;
int w= rec.width();

button->setMinimumSize(w,h); //this button will fit inside the screen with full width
button->setMaximumSize(w,h);

with the resize I just see a part of the button and I should see it complety.

Thanks.

So what is your question?

How is setting a fixes size on a button related to resizing any window?

No,

My question is:

if my ui size its 300,300 and I put w.show() it will show up as 300 300. If I put a w.showFullScreen() it will be 1920x1080 which is my actual computer screen. What I want is to set that screen at 550x300 when showing it and I know that w.resize isn't the answer.

Hmm, resize should work. When you resize(550, 300) how large does the window appear?

w.show()
result: 300x300 which is the ui size


w.resize(550,300);
w.show();
result: 550 300 with just a little part shown of the buttons and things inside

BUT when I change to the next page (its a wizard structure with wizardpages) then the next page became full screen on the width ... dunno if its because the buttons inside are like I said in the first post.

w.resize(550,300);
w.show();

So, do I understand this correctly: then it shows by itself in 300x300 all "things inside" fit, but when you make it larger it no longer does?

Does the widget have a layout ?

[roseicollis]

Nop XD Sorry for my bad explanation. If I resize its like if I had the fullscreen with all the elements in their right place and size and I cut a square of 550, 330 more or less so I just see a part of a label, and a part of a button. And when I change to the next page, the app becames 1920x300 (the same high but the computer screen max width).

yes stampede

Show us your widget layout definition, please. And maybe show us a screenshot of what the problem is about.

Hi, I just found a way to do it:

I jsut fix it with setFixedSize(), and then change the sizes.

thank you for all :)

I don't know what this is supposed to accomplish but it's probably a very bad approach. I'm still suspecting you don't have a proper layout setup.
