How to do with resolution adaptation?

Limer

For better layout, I often use plain number to layout, such aslayout->setSpacing(20),font.setPixelSize(12);,etc...(I know setPointSize() can replace setPixelSize() to get better adaptation, here is just a example, ignore it.)

So, if you use plain numbers to layout your app interface, it will lost it's adaptation.

I think it deeply for some time, finally find a way: by using resolution proportion.

for example,

QSize currentResolution = getResolution();
double resolutionProportion = currentResolution.width() / 1920.0; // 1920 is the resolution's width of your pc on which develop this app
...
...
...
layout->setSpacing(20 * resolutionProportion );

Is this a good solution? If not, could you tell me the better or best solution?

Thanks a lot.

Hi
You are using an int for resolutionProportion so i fear it will be truncated and zero
for most cases.
To have effect, i think you need something like

double resolutionProportion = (double )currentResolution.width() / 1920.0;
layout->setSpacing( ceil(20 * resolutionProportion ));
(or floor or round )

Other than that, i think the idea is fine enough.

@mrjj Yes, yes....I wrote it wrong, sorry, thanks for your response.
