QSplitter like a "grid" splitter [Using qt 4.4]

[yandy]

Hi,

my problem is the following

I have several widgets I want to layout in a grid style and I also want to
have the QSplitter sizing features.

With QSplitter i only can layout the widgets horitzontally or vertically but
not in a grid with a handle in the centre to resize the widgets at the same
time.

For example, if I have 4 widgets like this picture

(such as 1.png in attachment)

if I move the handle in the centre to the right then

(such as 2.png in attachment)

if I move the handle in the centre down then

(such as 3.png in attachment)

I've seen this kind of feature in some windows app's but I don't know if
this is possible using qt 4.1.

I would like to know if there's a way to do that with the actual
QSplitter's. Although if somenone has tried something similar and can give
some hints to do it with another classes to get a similar result

Thanks.

We also can read small texts!

In one orientation you have one QSpliter in the other you have two.
QSplitter s1 = new QSplitter(Qt::Horizontal);
QSplitter s2 = new QSplitter(Qt::Horizontal);
// add 2 widgets to each of them
QSplitter s3 = new QSplitter(Qt::Vertical);
s3->addWidget(s1);
s3->addWidget(s1);

Now connect s1 and s2: sX::splitterMoved( int pos, int index ) to sY->handle(index)::moveSplitter(pos). (and vice versa!)

Not tested but should work.

Thank you for your reply.But,maybe, I haven't expressed my problem properly. I'd like to move the point at the cross centre of the 4 splitter widgets to resize all of them four at the same time.Not just move "up to down" or "left to right". Thanks

then extend the sample by an own splitter handle for s3 (painted at the position of the handles s1/s2). Use mouse tracking to get the coordinates and emit proper signals which are connected to s1 and s2. Pack all in one widget with an function setWidgetInSplitter(...).
Easy :cool:

Thank you,Let me have a try

Go on, that's some work to get thinks work right. When you are ready, share your knowledge with us :)

This is an old thread, but I don't quite understand Lykurg's suggestion. moveSplitter() is a member of QSplitter, not QSplitterHandle. Further, it's a protected function. So I can't figure out how to get it to work. Any ideas?

You could subclass it to access it, but you don't need it. It was mainly an example on how to do it theoretical. Use QSplitter::setSizes() to set the size of the spliter. (for that you have to create a custom slot!)

void slotForS2Moved() {
s1->setSizes(s2->sizes());
}
