wxColourPickerCtrl->GetColour() method crashes PHP #111
Description
Activity
FYI this works fine on GNU/Linux/Ubuntu 14.04:
The
print_r()doesn't show the contents, but this is normal behaviour in my experience - I expect the data is still available with the right properties/getters.@halfer:
print_r()works in debug mode (using .wxphpd extension)
This crash happens not just on wxColourPickerCtrl, but it happens on calling GetColour(), GetForegroundColour() or GetBackgroundColour() method in other objects too.
Here are the screenshots after pressingMyButton:
@halfer: As I had written previously, it is really a crash and therefore there is no error message. I do not have debug tools on my windows system, so I cannot attach debug logs. That is the reason, that I cannot debug and solve the problem and make suggestion to correct it. All, that I can do is to report the phenomenon and attach a sample wxphp code which can help to reproduce the crash on windows 10.
Beside this, I can attach a screenshot about application log from control panel, but it does not contain any additional information about the exact error:
Your screenshot illustrates exactly the point I was making @raernon - thanks for adding it. Windows was hiding a great deal of information in your previous screenshot, but the new one adds more detail. I agree the new details aren't particularly self-explanatory, but it does at least include version numbers and fault codes. We also now know it is Windows 10, which might be relevant.
Do you get this behaviour on any other versions of Windows? I don't run Windows at all myself, but running older versions through a virtual machine may help to determine if it's new on W10, or has always been an issue on Windows.
Do you get the crash if the
print_r()is removed? I'm not clear whether exposing the palette is causing the crash, or clicking a colour.I get the crash when I call the GetColour() method. It is independent from print_r() function. But it crashed on GetBackgroundColour() and GetForegroundColour() methods too.
OK. Would you be in a position to try this on any other versions of Windows? (I don't know what the cause is, just making suggestions to help someone digging into the internals in the future).
@jgmdev: is there anything the OP can do to provide more detailed fault information from Windows? I wonder if there is a debugging mode available, for example?
I have installed vmware player, windows xp sp3 and the same crash happened, so this bug affects every windows builds.
Here is a screenshot of the line of code with values of exception break. File is pickers.cpp line 479.

The wxColourPickerCtrl->GetColour() method crashes PHP under windows. I've tried both x86 and x64 versions of wxPHP (wxphp-3.0.2.0-php5.4-x86.exe and wxphp-3.0.2.0-php5.5-x64.exe)
I've created a sample code with wxFormBuilder: I've dropped a colourpicker and a button control on a frame, all controls with default properties. The button has an onclick event which try to read the colourpicker actual colour value. When the button pressed, the PHP crashes.
