position and size of current viewport

[Alexey Vanzhula]

Yes, you right.

[Alexey Vanzhula]

So if at least one viewport show:

1. get window with ID=0 -> main window

2. get window with ID=1 -> viewport window

it is good

But

if all viewports in currect desktop are hidden and opened at least one floating window - we get wrong viewport window (with ID=1)

So, i need something like isFloatingWindow()

[Alexey Vanzhula]

Other question:

Is it possible to add callback for change window size? I dont find solution

Look at enum RE_WindowType:

http://www.sidefx.com/docs/hdk13.0/_r_e___types_8h_source.html

cout << currentWindow->getWindowType() << endl;

Main Window will return 0, that means RE_WINDOW_MAIN. Viewport will return 6, that means RE_WINDOW_CHILD. And it return 6 even if we tear of pane. Other windows (tooltips, parameter etc) return other values. I don't know is there any other window that return 6 beside another viewport.

I have a problem.

When i change viewport size it gives me wrong x and y components ( w and h change normally )

look at this video:

Drag&drop your node to python shell and call on it cook(), so you should get something like this:

hou.node('yournode').cook(force=True)

Now try to change viewport size, then execute the same line in pythonshell and press button on your node. Does it help?

It does not help

[Guest mantragora]

Than you are doing something wrong. If I don't recook the node I also get incorrect reading if I rescale viewport. But when I added to my button callback cook() it updates values correctly.

[Guest mantragora]

You got some code in your button callback field? add after your callback cook(), so it look like this:

yourcallback(), hou.pwd().cook(True)

Does it help?

[Alexey Vanzhula]

It is very funny:

As you can see if i simple press mouse button on size-border after drag it (and before next update callback) - it updates normally.

Any ideas...

Yes i added cook before and after callback - nothing changed

[Guest mantragora]

I don't know. Can't say anything without testing this myself. It may be only Linux thing.

[Alexey Vanzhula]

this is my quick test (button callback) code

import inlinecpp

def alignMayaViewport( node ):
    mymodule = inlinecpp.createLibrary(
    name='test',
    acquire_hom_lock=False,
    includes=
    '''
    #include <RE/RE_Render.h>"
    #include <RE/RE_window.h>"
    ''',
    structs=[("IntArray", "*i")],
    function_sources=[
    """
    IntArray test()
    {
    RE_Render* render = RE_Render::getMainRender();
    RE_WindowList* winList = render->getWindowList();
    int winCount = winList->getNumWindows();

    int i=0;
    while (i < winCount)
    {
            RE_Window* win = winList->getWindow(i);
            if ( win->getWindowType() == 6 )
            {
                    int ints[] = {win->getX(), win->getY(), win->getW(), win->getH()};
                    std::vector<int> vec (ints, ints + sizeof(ints) / sizeof(int) );
                    return vec;
            }
            i++;
    }

    int ints[] = {0, 0, 0, 0};
    std::vector<int> vec (ints, ints + sizeof(ints) / sizeof(int) );
    return vec;

    }
    """])

    l = mymodule.test()

    # print l[0], l[1], l[2], l[3]

    # exec_ send cmd to Maya via commandPort
    exec_( 'ui.qMayawindow.move({0},{1}); ui.qMayawindow.resize({2},{3})'.format(l[0],l[1],l[2],l[3]), node )[/CODE]

If you print values, do you always get correct ones? On Windows it looks like it updates them correctly.

[Alexey Vanzhula]

No. But If i click on border before update it return valid values.

I also think that it is linux problem. I tried a few window mangers - same result.

[Alexey Vanzhula]

Can you show your test code?

[Guest mantragora]

I took yours and added just button with callback to my node and also moved inlinecpp module outside of you function. I'm just calling it inside and printing values. This is all I can check since I don't have Maya.

[Guest mantragora]

The only moment I get incorrect corner position is when I tearOff viewport pane. Then it always prints position as [12,119]. Beside this situation it updates OK.

ACTUALLY, It is correct if I tear off pane too BUT I just realized that viewport corner is counted from its parent corner. So if your viewport is inside your MainWindow and you move your MainWindow, to get correct corner position for the whole screen you need to take into account both positions.

If you tearoff viewport to separate window it always shows position as [12,119] because it doesn't change it's position like it is when you change pane size inside main window. In this situation the only changing value is the position of parent window that keeps the viewport.

Most likely it is not possible with HDK, but nevertheless... I need to emulate click on any pane border (border that change size of pane).

And in general: how to emulate mouse click? I see HDK documentation and think that it is possible but i still the layman in these questions )
