Change WxPropertyGrid based on button click Topic is solved

[gillp28]

I have a property window that is going to be controlled from the list. Every item on the list corresponds to the same property window but with different colour and label values. The colour is just going to be the background colour of the item. The only question i have is how do i change a property or the colour that has been appended to the wxPropertyGrid based on a new selection.

grid = new wxPropertyGrid(treePanel, wxID_ANY, wxDefaultPosition, wxDefaultSize, wxPG_AUTO_SORT | wxPG_SPLITTER_AUTO_CENTER| wxPG_DEFAULT_STYLE);
wxPGProperty* prop = grid->Append(new wxColourProperty(wxT("Label Colour"),wxPG_LABEL,wxColour(242, 109, 0)));

You will need to read this first
In your case you will need to catch relevant event.
To understand which item was clicked you will need to catch event of interest and use the unique names to differentiate items

//add the property in the grid
m_editorGeneralProps->Append(new wxPropertyCategory(_("Label"), "unique-name-here"));

Code: Select all

void MyClass::OnGridPropChanged(wxPropertyGridEvent &event) // catching wxEVT_PG_SELECTED
{
    wxPGProperty *property = event.GetProperty();
    wxString name = property->GetName();
    wxVariant value = property->GetValue();
    
    if(name == "unique-name-here")
    {
    	//change color here
    }
}

wxPGProperty* pg = grid->Append(new wxColourProperty(wxT("Label Colour"),wxPG_LABEL,
wxColour(242, 109, 0)));

grid->ChangePropertyValue(pg,new wxColourProperty(wxT("Label Colour"), wxPG_LABEL,
wxColour(*wxBLACK)));

if I just want to change the colour property can I do it using the change property value? I tried this but it's not working

[evstevemd]

wxPGProperty* pg = grid->Append(new wxColourProperty(wxT("Label Colour"),wxPG_LABEL,
wxColour(242, 109, 0)));

grid->ChangePropertyValue(pg,new wxColourProperty(wxT("Label Colour"), wxPG_LABEL,
wxColour(*wxBLACK)));

if I just want to change the colour property can I do it using the change property value? I tried this but it's not working

Do you want to do that immediately or you do it in some handler? Can you make small example?
I have never tested this but if you want to change property you can try this

Code: Select all

void MyClass::OnGridPropChanged(wxPropertyGridEvent &event) // catching wxEVT_PG_SELECTED
{
    wxPGProperty *property = event.GetProperty();
    wxPGPropArgCls pid(property);
    
    wxColor color = *wxBLACK;
    wxVariant value(color);
    grid->ChangePropertyValue(pid, value);
    
}

Cannot help further without illustrating your case with sample example of what you are doing!

[gillp28]

This is the sample I'm working on. So based on the item selected on the listview the property window selected colour changes.

Code: Select all

wxTreeCtrlFrame::wxTreeCtrlFrame(wxWindow* parent, wxWindowID id)
{
	Create(parent, id, wxEmptyString, wxDefaultPosition, wxDefaultSize, wxDEFAULT_FRAME_STYLE, _T("id"));
	SetClientSize(wxSize(500, 500));

	wxPanel* treePanel = new wxPanel(this, wxID_ANY);
	wxBoxSizer* mainSizer = new wxBoxSizer(wxVERTICAL);
	wxBoxSizer* horSize = new wxBoxSizer(wxHORIZONTAL); 

	listView = new wxListView(treePanel, ID_TREELISTCTRL1, wxDefaultPosition, wxDefaultSize);
	wxListItem NewItem;
	grid = new wxPropertyGrid(treePanel, wxID_ANY, wxDefaultPosition, wxDefaultSize, wxPG_AUTO_SORT | wxPG_SPLITTER_AUTO_CENTER| wxPG_DEFAULT_STYLE); 
	mainSizer->Add(listView, 1, wxEXPAND | wxALL, 4);
	mainSizer->Add(grid, 3, wxEXPAND | wxALL, 5); 

	horSize->Add(addNodeBtn); 
	horSize->Add(deleteNodeBtn);
	horSize->Add(editNodeBtn); 
	mainSizer->Add(horSize, 0 , wxALIGN_TOP | wxALIGN_RIGHT | wxTOP | wxRIGHT | wxBOTTOM, 4);
	treePanel->SetSizer(mainSizer);

	listView->AppendColumn("Column 1");
	listView->AppendColumn("Column 2");

	// Add three items to the list
	listView->InsertItem(0, "Item 1");
	listView->SetItem(0, 1, "Amber");
	listView->SetItemBackgroundColour(0, *wxRED); 
	listView->InsertItem(1, "Item 2");
	listView->SetItem(1, 1, "Blue");
	listView->SetItemBackgroundColour(1, *wxRED); 

	listView->InsertItem(2, "Item 3");
	listView->SetItem(2, 1, "Cyan");
	listView->SetItemBackgroundColour(2, *wxRED); 

   pg =  grid->Append(new wxColourProperty(wxT("Label Colour"),wxPG_LABEL,
		wxColour(242, 109, 0)));

	Connect(idMenuQuit, wxEVT_COMMAND_MENU_SELECTED, (wxObjectEventFunction)& wxTreeCtrlFrame::OnQuit);
	Connect(idMenuAbout, wxEVT_COMMAND_MENU_SELECTED, (wxObjectEventFunction)& wxTreeCtrlFrame::OnAbout);
	Connect(ID_TREELISTCTRL1, wxEVT_COMMAND_LIST_ITEM_SELECTED, (wxObjectEventFunction)& wxTreeCtrlFrame::OnNodeSelected);
	//*)
}


wxTreeCtrlFrame::~wxTreeCtrlFrame()
{
	//(*Destroy(wxTreeCtrlFrame)
	//*)
}

void wxTreeCtrlFrame::OnQuit(wxCommandEvent& event)
{
	Close();
}

void wxTreeCtrlFrame::OnAbout(wxCommandEvent& event)
{
	wxString msg = wxbuildinfo(long_f);
	wxMessageBox(msg, _("Welcome to..."));
}

void wxTreeCtrlFrame::OnNodeSelected(wxTreeListEvent& event)
{
	 wxColour back = listView->GetItemBackgroundColour(listView->GetFocusedItem());
	 grid->SetPropertyValue(pg, new wxColourProperty(wxT("Label Colour"), wxPG_LABEL,
		 back));
}

Looking at your code, why do you even use wxPropertyGrid? You have only one property that need to change color.
Have you checked wxColorPickerCtrl?

[gillp28]

I will be adding more properties after but for now just trying to get the colour part to work.

Appending change it to include unique name

Code: Select all

pg =  grid->Append(new wxColourProperty(wxT("Label Colour"),"unique-name-here", wxColour(242, 109, 0)));

Then try this code for event. Untested but according to docs it should work

Code: Select all

void wxTreeCtrlFrame::OnNodeSelected(wxTreeListEvent& event)
{
	 wxColour back = listView->GetItemBackgroundColour(listView->GetFocusedItem());
	 wxPGPropArgCls pid("unique-name-here");
    	wxVariant value(back);
    	grid->ChangePropertyValue(pid, value);
}

Did that work?
