FR: Option to allow ComboBox to reselect the same item

[stephenk]

Presently, it is impossible to reselect the same item from a ComboBox - it is filtered out.

However, this can be a useful expected behavior, as in the case of reselecting a preset in order to blow out any edits. This has been discussed in multiple threads here.

Therefore, it seems it would be really easy to add this as an option. It’s basically a one line edit to the .cpp file and the inclusion of a bool variable.

Something like this:

ComboBox.h:

public:
	void setCanReselectSameItem(const bool state) { canReselectSameItem = state; }

private;
    bool canReselectSameItem = false;

ComboBox.cpp:

void ComboBox::setSelectedId (const int newItemId, const NotificationType notification)
{
    auto* item = getItemForId (newItemId);
    auto newItemText = item != nullptr ? item->text : String();
    
    //if (lastCurrentId != newItemId || label->getText() != newItemText)
    if (canReselectSameItem || (lastCurrentId != newItemId || label->getText() != newItemText))
    {
        label->setText (newItemText, dontSendNotification);
        lastCurrentId = newItemId;
        currentId = newItemId;

        repaint();  // for the benefit of the 'none selected' text

        sendChange (notification);
    }
}

ComboBox: Handling item reselection

What is the proper way of getting notified when the user selects the same item in a ComboBox that is currently selected? What I tried so far with no success: Overriding comboBoxChanged or valueChanged or handleAsyncUpdate in a subclassed ComboBox. All of those methods get only called if the value actually changed. What I tried with partial success: Passing a PopupMenu::CustomCallback that handles menuItemTriggered() to every PopupMenu::Item in the ComboBox. Problem here is that the callback…

How to add a function that will be triggered when the same item has been selected in the combobox?

I have been trying to override combobox class to add this feature but nothing worked. Combobox calls comoboboxChanged function when we select an item from its popup menu but it does not do anything when we try to reselect the same ( already selected and ticked ) item. I overrode the drawcombobox and drawComboboxItem to change the font of the popup menu items. But I could not find a way to get the mouse down event of the combobox popup menu. It is defined in its class but it is internal. I just …

comboboxChanged is not being called when i click on the same item

Does anybody know a way to solve this issue ? I am using a combobox to display my presets and after loading a preset, user can change many things but if the user does not want to keep it like that or reload the unmodified preset, he/she will try to go to combobox again and click on the same preset. At that moment the preset should be reloaded but I when i try to click on the same item, it does not call comboboxChange. I tried to do it by using mouse down event, resetting selected id,… noth…

I already used my two votes, but we would definitely like this, as well!

OT, but afaik you should have 5 votes…?

Check on your User-Icon -> Activity -> votes

Also OT, but related: at what point do we give up hope on requests that are using votes?

Most of mine are on requests that are 2 years old now.

I wish there was a public roadmap to see what the team is working on/will be tackling next, it could even just be a pinned topic with comments disabled that they update periodically.

These kind of questions are considered lèse-majesty and ignored generously instead of incarceration

Setting ComboBox's PopupMenu colors

Btw. What happens to feature requests that you decide not to fix despite being the fifth most voted feature request?
