encountering scol .exe crash with modified plugit

colleagues:

I`m encountering a crash (scol.exe has stopped working window, os3d editor quits without indicating any error in the editor log window with the my modified plugit on its cbresize callback.  perhaps I am casting from one basic type to another and the compiler is not detecting the illegal cast? is
app data>local>scol voyager > logs  the only place to look for an eror

the crash is happening with the cbresize callback.  all I am doing is setting some struct I (interger) fields to the new ones following computePosSize.

I'm pretty sure my code is to blame but I don't knno where to look.

(I tested the original cbutton with the same configuration no crash there)

I added some fields to the button struct, put in some if then tests to prevent multiple fingers from controlling button (it allows only one control), along with creating and destroying the touchpoint widget i add when only one finger is contacting the button.

something is making the button height and width radically increase if and only if percentages are being used instead of pixel height and width...the increase happens in the computepossize function, even though i cannot find anything multiplying the button width and height fields.

Re: encountering scol .exe crash with modified plugit

for some reason if i set the button width to 10, and check % directly to the right, when the code extracts the btnstr.PBTN_tPercent tuple, the third item of the list turns into 8....hmph

Re: encountering scol .exe crash with modified plugit

whatever you do you should not encounter a crash.

can you make a zip of your plugIT and send it to me with an xos scene that make it crash ?

Re: encountering scol .exe crash with modified plugit

Your size callback and calculation are bad, and you try to create a too huge bitmap size.
Ogre return an exception because of a memory issue.

I added a try catch for this  case to try to prevent the crash but you should correct the code anyway.

Re: encountering scol .exe crash with modified plugit

if you change the values in the resize callback that are definied in the editor, and this values are used to compute the position and size.
So you get an incremental behavior.

if you want to get the current widget pos and size use directly widget functions.
Do not change values that are used to compute the current position.

i see, so i use SO3WidgetGetPosition and SO3WidgetGetSize, etc.

this is strange, in your version of the button plugit you don't do this, you get the values from the struct. oh well, i will fix it and won't worry too much about how i broke it.

Re: encountering scol .exe crash with modified plugit

computePosSize calculate the new position of the widget on resize from the parameters set in the editor.
if you change btnstr.PBTN_iWidth or something else latter or in resize function the values will not be correct anymore.

aha, i see....well the only thing i guess i will have to recalculate are the horizontal and vertical centers of the button at each resize event, since i am varying output by offset from the center of the throttle. i know what to do i think. thx.

I did this in order to revise the horizontal center and offset values that control widget output... as you said, I will get those with the widget methods and set my struct according to the widget properties and not the initial values set in the editor.

Re: encountering scol .exe crash with modified plugit

I removed the setting of PBTN_iWidth and PBTN_iHeight cbResizeCtrl and the button is behaving itself (not incrementing in size). and resizing is resulting in the correct button vertical center values. will do more work later in weekend/early next week, thx guys
