QInputDialog_GetText crashes randomly about qt

[therecipe]

Hey

I'm aware of that, but all bool* parameters are currently ignored.
If you take a look at the widgets.cpp, you will see that the bool won't make it into the final call.

char* QInputDialog_QInputDialog_GetText(void* parent, char* title, char* label, int mode, char* text, int ok, int flags, int inputMethodHints)
{
    return QInputDialog::getText(static_cast<QWidget*>(parent), QString(title), QString(label), static_cast<QLineEdit::EchoMode>(mode), QString(text), NULL, static_cast<Qt::WindowType>(flags), static_cast<Qt::InputMethodHint>(inputMethodHints)).toUtf8().data();
}

I'm planning to make them usuable (change them from bool to *bool on the go side) and also pass them all the way into the c++ call, but I haven't found time for it yet.

But, I tested the code below and it works for me.

So, could you provide me a snipped of your code, so I can reproduce the problem?

package main

import (
    "os"

    "github.com/therecipe/qt/core"
    "github.com/therecipe/qt/widgets"
)

func main() {
    widgets.NewQApplication(len(os.Args), os.Args)

    var button = widgets.NewQPushButton2("open dialog", nil)

    button.ConnectClicked(func(_ bool) {
        button.SetText(widgets.QInputDialog_GetText(button, "Title", "Label", widgets.QLineEdit__Normal, "Text", false, core.Qt__Dialog, core.Qt__ImhNone))
    })

    button.Show()

    widgets.QApplication_Exec()
}

I have tested it more trying to extract code however as soon as i rip it away from my code base, it starts acting stable.
I tested the code the below code nearly a 100 times and it crashed just once
so i assume the problem is still there.

package main

import (
    "os"
    "fmt"
    "github.com/therecipe/qt/core"
    "github.com/therecipe/qt/widgets"
)


 func main() {

        widgets.NewQApplication(len(os.Args), os.Args)

        var widget = widgets.NewQWidget(nil, 0)

//this crashes because of boolean paramter which should be a pointer
        var u = widgets.QInputDialog_GetText(widget, "title Enter username", "Enter username",
            widgets.QLineEdit__Normal, "", true, core.Qt__Dialog, core.Qt__ImhNone)

        fmt.Printf("user entered %s\n", u) 

}

Hey

I looked into this again and tested the static function QInputDialog::getText manually (100 times), but it didn't crash.
And I also used the code below to test if a manually created QInputDialog would crash, but it didn't.

I'm using go1.7beta1 darwin/amd64, OS X 10.11.5 and Qt 5.7

Please try to find an example which crashes more often.

package main

import (
    "fmt"
    "os"
    "time"

    "github.com/therecipe/qt/core"
    "github.com/therecipe/qt/widgets"
)

func main() {
    widgets.NewQApplication(len(os.Args), os.Args)

    var widget = widgets.NewQWidget(nil, 0)

    for i := 0; i < 200; i++ {

        var dialog = widgets.NewQInputDialog(widget, core.Qt__Dialog)
        dialog.SetWindowTitle("title Enter username")
        dialog.SetLabelText("Enter username")
        dialog.SetTextEchoMode(widgets.QLineEdit__Normal)
        dialog.SetInputMethodHints(core.Qt__ImhNone)

        dialog.ConnectAccept(func() {
            fmt.Printf("user entered %s\n", dialog.TextValue())
            dialog.AcceptDefault()
        })

        go func() {
            time.Sleep(25 * time.Millisecond)

            dialog.SetTextValue(fmt.Sprint(i))

            dialog.Accept()
        }()

        dialog.Exec()
    }
}
