Does creating apps without any layouts create any problems ?

[Ahti]

@Pradeep-Kumar if i use layouts then no matter if its fixed size or not it won't give any issues right ?

@Ahti We can't of course guarantee you won't run into problems with Layouts but you will have much less problems with them than without. Of course you have to learn to use them, but that time and effort is well spent. In general you will avoid many problems later if you just make your UIs more general and responsive with Layouts, no matter what your needs are at the moment.

I suggest learning the Layout concepts with Qt Creator Design view. Add a Layout and some items into it and play with the Layout's own properties and the Layout attached properties of the items inside the Layout. Then try nested Layouts. Even if you prefer coding UIs by hand it's often easier to create a mockup using the Design view and then continue manually.

@Ahti
if you give fixed size based on resolution of the different devices, then i wont give any issues but if you directly give the size it wont align properly.

Hi,

@Ahti

u need to look into consideration of all platforms, and then move ahead, not only using fixed sizes for apps, later point of stage, requirement may vary, in that point re doing everything, time effort and requirement, come into picture so now plan well on how u design .

Thanks,

@Ahti What is the background of your question? You don't want to use layouts? If so why?

[Ahti]

@jsulm I was working on a project in my old pc but now i brought a new pc and i moved the same project in my new pc ( which has a different resolution ) but now when i run the same project on my new pc all the text and some widgets get out of alignment and for that reason i had left that project as its. I didn't used any layout in the project so now i thought maybe its because of these layouts why it looks so ugly.

@Pradeep-Kumar but for desktops the minimum resolution is 800600 and i have put the fixed size to 600400 and i also check if the resolution is below that then the app should throw error saying "resolution not supported"

Seeing this, 2 things come to mind.

Your new PC has a high-dpi (dots per inch) display or a different scaling factor is set for your display.

Either way

QApplication::setAttribute(Qt::AA_Use96Dpi);

before

QApplication a(argc, argv);

should do it as a quick and dirty workaround. :-)

@Ahti That is a perfect example why you SHOULD use layouts and what happens if you don't.
Just use layouts (it is really not hard) and you will not have such problems.

@jsulm after using gridlayout the text appears small why ? have a look:

@Ahti
Hi
Font size is varies from device to device based on their screen resolution. so that before going to give font size calculate with screens dpi and set the size.

[jsulm]

@Ahti If the font is too small then increase its size
