Can anyone give an example of using the media player / video widget? I'm having trouble translating the Qt 5.5 examples.. Thanks.

(btw, maybe there should be a forum or google group?)

I am trying to rewrite some PyQt app in Go using this bindings. Can uitools somehow load resource files that are included in .ui files?

I also tried to use go-bindata to include icons in binary, but QPixmap LoadFromData2 always returns libpng error: Read Error . This is what I tried so far https://gist.github.com/gen2brain/2d56084e797d98cf26703142613d438b .

How to get return value from slot ?
for example:

type SignalHandler struct {
core.QObject
_ func(a int, b int) int           `slot:sum`   
}

How to get result of the sum function?

Don't known why, but it will fail to translate the QML files when create QmlEngine from go.
I tried to create QmlEngine from c++ and the translator works.

    func mousePressEvent(e *widgets.QGraphicsSceneMouseEvent) {
        var color = gui.NewQColor2(160, 160, 160, 255) // r,g,b,a
        var pen = gui.NewQPen3(color)
        pen.SetWidth(1)
        var brush = gui.NewQBrush()

        scene.AddRect2(float64(e.ScreenPos().X()), float64(e.ScreenPos().Y()), 5, 10, pen, brush)

    }

AddRect only accepts a float64. Your version of QGraphicsSceneMouseEvent uses only ScreenPos which returns a QPoint, not QPointF.

Running this, the rectangles appear 100 pixels from where the mouse cursor actually is in the scene.

Maybe I have done something wrong?

Compile time is too long...
Will this be fixed future

I have xCode and QT installed on my computer and when I try to go-get the package I get an error: stat ./internal/setup/check.go: no such file or directory. How can I fix this?

Event filters are not working (i am testing on linux x64), when i try it on a QPlainTextEdit control. I have tried different ways, but still not able to figure out how to get this done. I am new to GO, QT and ofcourse the bindings, so can't figure it out myself ( Too many new things i know at this time ).

when i use InstallEventFilter method, i get this as compile error.
widgets.QPlainTextEdit does not implement core.QObject_ITF (missing QObject_PTR method)

Also, i tried using various Connect methods for events such as ConnectEventFilter, ConnectKeyPressEvent, ConnectEvent but in all the case i was not able to catch any events. Also, no compile time/runtime error occurs.

btw, extremely good work, this seems to be a holy grail, because using the binding is easy rather than clumsy C.This might easily take the place of https://github.com/google/gxui, if more documentation, examples are provided.

Thank you very much for making such an amazing library.
I ran into a problem today. I want to subclass a QObject to add some signals and slots and then pass the pointer to QmlEngine so I can call go functions from QML. This can be done easily in c++ , but how to do this with golang?

Dear Sir,

Do you think is possible to provide us with .a libraries for the ARM processor?
Do you have any methodology how it could be done that?

Many thanks in advance for your answer
Dimitris

Hi,

I made this example as a base test of QGraphicsPathItem. I am using something like it right now that works but for some reason this example does not work. (edit: modified and still doesn't work..)

I wanted to test QGraphicsPathItem separately. I have added QGraphicsPathItem by using Scene AddItem but could not get RemoveItem to work.

    package main

    import (
        "os"

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

    var (
        canvas *widgets.QWidget
        scene  *widgets.QGraphicsScene
        view   *widgets.QGraphicsView
    )

    type line struct{ *widgets.QGraphicsPathItem }

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

        NewCanvas().Show()

        widgets.QApplication_Exec()
    }

    func NewCanvas() *widgets.QWidget {
        canvas = widgets.NewQWidget(nil, 0)
        scene = widgets.NewQGraphicsScene(nil)
        view = widgets.NewQGraphicsView(nil)

        var l = &line{QGraphicsPathItem: widgets.NewQGraphicsPathItem(nil)}
        l.ConnectBoundingRect(l.boundingRect)
        l.ConnectPaint(l.paint)

        scene.AddItem(l)

        view.SetScene(scene)

        var layout = widgets.NewQVBoxLayout()
        layout.AddWidget(view, 0, 0)

        canvas.SetLayout(layout)

        return canvas
    }

    func (l *line) paint(p *gui.QPainter, o *widgets.QStyleOptionGraphicsItem, w *widgets.QWidget) {
        var color = gui.NewQColor3(0, 0, 0, 255)
        var brush = gui.NewQBrush3(color, 0) // solid = 1, nobrush = 0
        var pen = gui.NewQPen3(color)
        pen.SetWidth(1)

        p.SetRenderHint(1, true) // Antiailiasing
        p.SetPen(pen)
        p.SetBrush(brush)

        path := gui.NewQPainterPath()

        sx, sy, tx, ty := 0.0, 0.0, scene.Width(), scene.Height()/2

        path.MoveTo2(sx, sy)
        path.LineTo2(tx, ty)
        p.DrawPath(path)
    }

    func (l *line) boundingRect() *core.QRectF {
        return core.NewQRectF4(0.0, 0.0, scene.Width(), scene.Height()/2)
    }

var window = widgets.NewQMainWindow(nil, 0)
window.

When I type '.', it will be block a long time, without any prompt

try to run qtQml.exe and get a blank screen, no error messages

Hi,

Adding text works but as soon as I add a line or rectangle, the source compiles but the executable doesn't run. Commenting out color, pen and addline2 produces a working file.

package gfx

import (
    "github.com/therecipe/qt/gui"
    "github.com/therecipe/qt/widgets"
)

var (
    canvas *widgets.QWidget
    scene  *widgets.QGraphicsScene
    view   *widgets.QGraphicsView
)

func NewCanvas() *widgets.QWidget {
    canvas = widgets.NewQWidget(nil, 0)
    scene = widgets.NewQGraphicsScene(nil)
    view = widgets.NewQGraphicsView(nil)

    font := gui.NewQFont2("Meiryo", 20, 2, false)
    scene.AddText("Hello 世界", font)

    var color = gui.NewQColor2(255, 0, 0, 1)
    var pen = gui.NewQPen3(color)

    scene.AddLine2(20, 20, 20, 20, pen)

    view.SetScene(scene)

    var layout = widgets.NewQVBoxLayout()
    layout.AddWidget(view, 0, 0)

    canvas.SetLayout(layout)

    return canvas

}

For future reference, seeing as I can't delete this, in case someone else runs into the same/similar issues..

First issue was with an "out of memory" error during the widgets part of the "install" routine. Fixed by reinstalling Go (I had the same version, but it was custom built so probably something about the compile limiting memory usage or something I'd guess)

Second error I got was "bad reloc address 0x4 in section `.data'" during install routine for uitools. The cause was that it referenced/used my local mingw install and not the one I installed as part Qt.

Hi, great project ! But it seems only working under Qt 5.5.1. And this morning i tried for replacing all "5.5.1" with "5.6.0", I know it's a foolish move, i got a lot of path not found error.

So any chance to support Qt5.6? or add an option to choose the qt version?

I uploaded the graph editor I've been working on. It's very incomplete but I need to stop here because the screen updates just don't work.

Left click on screen to plot rectangle

If you have two rectangles you can click on one and click on the other and it will draw a connecting line.

Right click to delete rectangle. This should also delete the lines connected to it.

Left clicking the top right of rectangle switches into Move mode. Clicking again will drop the rectangle where you moved it to.

All this appears to work.

However if you play around you can see:

Sometimes the line to draw the connections will stay on the screen even though there's already been a RemoveItem call.

If you move the rectangle and drop it then right click to remove, the node will disappear from the list on the left panel but the image will persist on the screen. So will it's edges. And if it's connected to another rectangle and you move that rectangle, the edge will follow as if it hasn't been deleted but it has.

I will try to strip this project down to the bare minimum so as to be a good example program for others but at the moment the scene updates don't work right.

Original define is

QString QInputDialog::getText(QWidget * parent, const QString & title, const QString & label, QLineEdit::EchoMode mode = QLineEdit::Normal, const QString & text = QString(), bool * ok = 0, Qt::WindowFlags flags = 0, Qt::InputMethodHints inputMethodHints = Qt::ImhNone)

your definition is

func QInputDialog_GetText(parent QWidget_ITF, title string, label string, mode QLineEdit__EchoMode, text string, ok bool, flags core.Qt__WindowType, inputMethodHints core.Qt__InputMethodHint) string {
    defer qt.Recovering("QInputDialog::getText")

    return C.GoString(C.QInputDialog_QInputDialog_GetText(PointerFromQWidget(parent), C.CString(title), C.CString(label), C.int(mode), C.CString(text), C.int(qt.GoBoolToInt(ok)), C.int(flags), C.int(inputMethodHints)))
}

if you see carefully, the ok bool parameter is a pointer, which causes the application to crash randomly.similiar bug appear in various other forms of QInputDialog.

There are many interface methods named xxxxx2(...),xxxx3(...)

Will these interface methods be renamed future?

I run this example:
therecipe\qt\internal\examples\widgets

And then run the exe file
therecipe\qt\internal\examples\widgets\deploy\windows\widgets.exe

Error Msg:

we just build desktop classic app ,just need qtbase/qtwidget.
almost people just need one useful uilib,but none,so build gui with c++.

Hi,

Using Win7 64-bit. Check out Line Edits example. Just cursoring over application window, application memory keeps increasing.

This didn't happen on the video player example.

I noticed this in my graph app.

Thanks

During the execution of setup.bat with administrator account I come across to this message

During the generate-phase says that "can't load package: .../therecipe/qt/core
nobuildable Go Source files in c:\prog\gopath\src\github.com\the recipe\qt\core.

1. Before TheRecipe you changed the source code to use the GOROOT env variable (thanks for that) i was managed to build the code but, it couldnt see to be able to link the core.a library.

I do not know if there is any implication by using the administrator account during the creation of .a files, a file takes elevated privileges.

Thank you in advance.

P.S. A GO/QT executable, using 2 only widgets weighs a lot in MB?

is it already implemenTed?
if yes, how to use it?

Am I doing this right?:

var list = widgets.NewQListWidget(nil)
list.ConnectKeyPressEvent(func(event *gui.QKeyEvent) { keyPressEvent(event) })

...

func keyPressEvent(event *gui.QKeyEvent) { ... }

Hello,

Do you have plans to implement these?

Currently NewQTableViewFromPointer / NewQTableWidgetFromPointer exist.

Also, gui.NewQPixmap?

Thanks.

Will 'FromWinId' be supported? (http://doc.qt.io/qt-5/qwindow.html#fromWinId)

    var hw win.HWND
    ...
    hw = win.FindWindow(nil, syscall.StringToUTF16Ptr(windowName))

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

    var window = widgets.NewQMainWindow(nil, 0)

    w := gui.NewQWindow(nil)
    w.FromWinId(hw)
    x := widgets.CreateWindowContainer(w, nil, 0)

    window.SetCentralWidget(x)
    window.ShowMaximized()
    widgets.QApplication_Exec()

dll/so will save time when build. now, too long...

Hi tr :)

I saw you implemented webengine and gave it a try :)

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

    // Main Window
    var window = widgets.NewQMainWindow(nil, 0)
    window.SetWindowTitle("Browser")

    // Main Widget
    view := widgets.NewQWebEngineView(window)

    // Set Central Widget
    window.SetCentralWidget(view)

    var url = core.NewQUrl("http://doc.qt.io/qt-5/qurl.html", 0)
    view.Load(url)
    view.Show()

    // Run App
    widgets.QApplication_SetStyle2("fusion")

Hi,

Using QListWidget:

func (ptr *QListWidget) ConnectCurrentItemChanged(f func(current *QListWidgetItem, previous *QListWidgetItem))

func (ptr *QListWidget) CurrentItemChanged(current QListWidgetItem_ITF, previous QListWidgetItem_ITF)

I get error:

λ qtdeploy


build_1
output:# local/AM/controlbox/graphpanel
controlbox\graphpanel\graphpanel.go:102: cannot use gp.NodeList.CurrentItemChanged (type func(widgets.QListWidgetItem_ITF, widgets.QListWidgetItem_ITF)) as type func(*widgets.QListWidgetItem, *widgets.QListWidgetItem) in argument to gp.NodeList.ConnectCurrentItemChanged

error:exit status 2

I've used both:

type Nodelist struct{ *widgets.QListWidget }

func (n *Nodelist) CurrentItemChanged(current widgets.QListWidgetItem_ITF, previous widgets.QListWidgetItem_ITF) {

}

func (n *Nodelist) CurrentItemChanged(current *widgets.QListWidgetItem, previous *widgets.QListWidgetItem) {

}

When I run setup.bat on win7 I get generate message then:

and keeps repeating. I shut the console down. I then go to therecipe/qt directory (using cmder console app), list the dir and I get:

By only listing the directory!

Using windows to go to the directory or the cmd console prints the directory normally..

Btw thanks for your hard work attempting to get this ported over. This is very important work imo :)

Hi, therecipe. Thank you for this hard work.
I ran the example. And it works well without any error in my opensuse13.2!

Hi,

I am wanting to hook into events for rectangle, ellipse and text but it looks like these are not completely implemented yet:

QGraphicsEllipseItem
QGraphicsLineItem
QGraphicsPathItem
QGraphicsPixmapItem
QGraphicsPolygonItem
QGraphicsRectItem
QGraphicsSimpleTextItem
QGraphicsTextItem

Thanks

Really thank you for your wonderful effort.
Your guide is simple and understandable

Please during the execution of setup.bat (install_std_1 phase) I had the error
"output:go: cannot find GOROOT directory: c:\go"

My Go installation is not in C:\GO but is described from GOROOT
Can you change it generally to check GOROOT?

Thank you in advance

As an example using with QPainterPath:
http://stackoverflow.com/questions/16877667/qt-modify-pathitem

QGraphicsPathItem / QGraphicsItem is stubbed out.

I need to mix c++ with objective-c , I used to mix them in .mm files and compile into one project, will this library auto compile the *.mm files?

Hi tr - this is just something I was testing out.

Hi, help me please!
How can i use custom context menu with QTreeWidget?
I can't find ConnectCustomContextMenuRequested method.
Thanks!

I'm sorry to trouble you. I watch your course study. But when I had a problem, I couldn't solve it.
d:\gopath\src\github.com\therecipe\qt\core\core.cpp:4:30: fatal error: QAbstractAnimation: No such file or directory

compilation terminated

Do you plan on refine this library? Like qt.NewDialog instead of qt.NewQDialog_QWidget_WindowType and mirroring the Qt documentation.

Hi,

The moc generates method names that I am using so I have to rename those. But it is also using camelcase NewPackagename for my struct creations - which is kind of aggravating because I'm not sure what I should rename all my struct creators. I began putting underscores at the end of the method names to distinguish them. Now I am putting underscores behind the struct creators. Is it possible to have your moc program use these alternate name + underscore instead so my code doesn't look so strange?

Thanks

package controlbox

type Controlbox struct {
    *widgets.QWidget
    Mode            string
    Tool            string
    }

func NewControlbox(canvas *widgets.QWidget, statusbar *widgets.QStatusBar) *Controlbox {

    cb := &Controlbox{}
    ... }

controlbox\moc.go:56: NewControlbox redeclared in this block
        previous declaration at controlbox\controlbox.go:22

Is this possible or should I just use the Tree/Table Widget?

Hi,

Trying drag and drop with QListWidget. When I attempt to drop the cursor shows circle and slash as if it can't accept drops. Also on the MimeData there doesn't seem to be a Urls() method.

Thanks

    gp.ValueList = Valuelist{widgets.NewQListWidget(nil)}

    gp.ValueList.SetAcceptDrops(true)

    vlayout.AddWidget(gp.ValueList, 0, 0)

    gp.ValueList.ConnectDragEnterEvent(gp.ValueList.DragEnterEvent)
    gp.ValueList.ConnectDropEvent(gp.ValueList.DropEvent)

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

    type Valuelist struct{ *widgets.QListWidget }

    func (v *Valuelist) DragEnterEvent(e *gui.QDragEnterEvent) {
        e.AcceptProposedAction()
        //  if e.MimeData().HasUrls() {
        //      e.AcceptProposedAction()
        //  }
    }

    func (v *Valuelist) DropEvent(e *gui.QDropEvent) {
        //  if e.MimeData().HasUrls() {
        e.SetDropAction(core.Qt__CopyAction)
        e.AcceptProposedAction()
        e.SetAccepted(true)

        for _, i := range e.MimeData().Formats() { // Urls() ??
            v.AddItem(i)
        }
        //  }
    }
