Custom editor for a delegate

Maser

This is a good idea)
But since im trying to learn Qt, i will save it for the emergency plan)
When i have a customer who wants it the exact way he described it, i wanna know how to do it, no matter of the cost)
Have you an idea why the over cells interfere with my editor and how i can solve it?

I assume that click goes to real cell as the images is just painted over it
so u can not click on them as such.

Maser

No, i can. I told you. if i aim right in the black marked cell, i can click and unclick the three left items, i can also click the three right items. Just when i click anywhere in the tablecells, the editor is gone.

PS: Maybe i have to somehow resize the "working area" of the cell to to fit my editor. I mean the clickable area associated with the cell. Idea on that?

Hi
The cell has the size it has.

The Editor can be anything so it should be possible
to float a transparent widget where u paint the pics
and get the selection.

Can u show code for editor creation ?

Maser

class ClickableIconHolder : public QWidget
{
    Q_OBJECT
public:
    ClickableIconHolder(uint Mark, QWidget *parent = 0);
    QSize sizeHint() const Q_DECL_OVERRIDE;
signals:
    void editingFinished();
protected:
    void paintEvent(QPaintEvent *event) Q_DECL_OVERRIDE;
private:
    QHBoxLayout *hbLayout;
    ClickableIcon *ci1 = 0;
    ClickableIcon *ci2 = 0;
    ClickableIcon *ci3 = 0;
    ClickableIcon *ci4 = 0;
    ClickableIcon *ci5 = 0;
    ClickableIcon *ci6 = 0;
    ClickableIcon *ci7 = 0;
};

Here is the header of the editor-widget. I create some clickable QLabel and add them to a HBoxLayout, thats all in general. I dont do nothing in the paintevent yet.

I tried to go cardcore and draw the widget myself, with no parent pased to it, but the problem is, the delegate doesnt wait for my editor to pass the data, whem im not making the editor delegates child. Im afraid for that id have to dig deep in the delegates sourcecode...

@Maser
well unless u want to use the normals means (combo / popup dialog)
then yes i think
you should look around in delegate code to get good idea.

Maser

Nah, that would be a waste of time at this point. I just took QDialog as a parentclass to my editor, now i can click everything and after i positioned it, it stays where it should be. Im not done yet completly implementing it, but the appearance(apart of some big margins for the boundaries) is quite what i wanted.
Thanks so far))

@Maser
please post final look :)

That is the look now. I added a Qt::FramelessWindowHint flag and this seems to be the minimal size. I have not figured out yet how to reduze the margins.

mrjj

@Maser
Ok . looks nice.
Did you use a layout ?
It has margins.
http://doc.qt.io/qt-5/qlayout.html#setContentsMargins

"On most platforms, the margin is 11 pixels in all directions."

Maser

yes, the hboxlayout. Ok, i set the margins now. Looks better. Thanks again))
