Panel with Elements as Button - Click only works on panel Topic is solved

[Morfio]

Hi,

I want to write my own button-component. I've got a panel, on this a static bitmap and a static text. In my gui the event is pushed only if I click on the panel, but not on the static bitmap/text. How can I make them pushing the event, too?

Code: Select all

// lknopf.h
#ifndef LKNOPF_H_
#define LKNOPF_H_

#include <wx/wx.h>
#include <wx/event.h>

class LKnopf : public wxPanel {

	public:
		LKnopf(wxWindow *, wxWindowID, const wxString &, const wxString &);
		
	protected:
		wxBoxSizer *bsHauptanzeige;
		wxStaticBitmap *sbmpKnopf;
		wxStaticText *stBeschriftung;
};

#endif /*LKNOPF_H_*/

Code: Select all

// lknopf.cpp
#include "lknopf.h"

LKnopf::LKnopf(wxWindow *parent, wxWindowID id, const wxString &bild, const wxString &beschriftung) :
																	wxPanel(parent, id) {
	bsHauptanzeige = new wxBoxSizer(wxVERTICAL);
	sbmpKnopf = new wxStaticBitmap(this, -1, wxBitmap(bild, wxBITMAP_TYPE_PNG));
	stBeschriftung = new wxStaticText(this, -1, beschriftung);
	stBeschriftung->Connect(wxID_ANY, wxEVT_LEFT_DOWN, wxMouseEventHandler(LKnopf::klick));
	bsHauptanzeige->Add(sbmpKnopf, 0, wxALIGN_CENTER);
	bsHauptanzeige->Add(stBeschriftung, 0, wxALIGN_CENTER | wxTOP, 5);
	SetSizer(bsHauptanzeige);
}

Code: Select all

// Code with my own button (very dirty, just tests)
VAdministration::VAdministration(wxWindow *parent, wxWindowID id) :
								wxDialog(parent, id, _("Administration"), wxDefaultPosition, wxDefaultSize) {
	wxBoxSizer *test = new wxBoxSizer(wxHORIZONTAL);
	test2 = new LKnopf(this, ADMIN_TEST, _("anzeigen.png"), _("Anzeigenbearbeitung"));
	test->Add(test2);
	SetSizer(test);
	
	test2->Connect(wxID_ANY, wxEVT_LEFT_DOWN, wxMouseEventHandler(VAdministration::klick));
}

Thank you all,

It is the normal process.

If you look at the wxMouseEvent, it directly derives from wxEvent and not from wxCommandEvent so it is not passed to the parent window if not processed.

If you want this process, you must derive your own wxStatic* from the bases, use an event table to intercept mouse events and process them to the parent panel.

[Morfio]

Ok, I did it and it works perfectly. But how can I process the event I try to connect when I put more of my buttons in my application?

Code: Select all

// My Button
#ifndef LKNOPF_H_
#define LKNOPF_H_

#include <wx/wx.h>
#include <wx/event.h>

class LStaticText : public wxStaticText {

	public:
		LStaticText(wxWindow *, wxWindowID, const wxString &);
		
	protected:
		DECLARE_EVENT_TABLE()

};

class LStaticBitmap : public wxStaticBitmap {

	public:
		LStaticBitmap(wxWindow *, wxWindowID, const wxBitmap &, const wxPoint & = wxDefaultPosition, const wxSize & = wxDefaultSize, long = 0, const wxString & = _("staticBitmap"));
		
	protected:
		DECLARE_EVENT_TABLE()

};

class LKnopf : public wxPanel {

	public:
		LKnopf(wxWindow *, wxWindowID, const wxString &, const wxString &);
		
		void klick(wxMouseEvent &);
		
	protected:
		wxBoxSizer *bsHauptanzeige;
		LStaticBitmap *sbmpKnopf;
		LStaticText *stBeschriftung;
};

#endif /*LKNOPF_H_*/


#include "lknopf.h"

BEGIN_EVENT_TABLE(LStaticText, wxStaticText)
	EVT_LEFT_DOWN(LKnopf::klick)
END_EVENT_TABLE()

LStaticText::LStaticText(wxWindow *parent, wxWindowID id, const wxString &label) : wxStaticText(parent, id, label) {
}

BEGIN_EVENT_TABLE(LStaticBitmap, wxStaticBitmap)
	EVT_LEFT_DOWN(LKnopf::klick)
END_EVENT_TABLE()

LStaticBitmap::LStaticBitmap(wxWindow *parent, wxWindowID id, const wxBitmap &label, const wxPoint &pos, const wxSize &size, long style, const wxString &name) :
							wxStaticBitmap(parent, id, label, pos, size, style, name) {
}

LKnopf::LKnopf(wxWindow *parent, wxWindowID id, const wxString &bild, const wxString &beschriftung) :
																	wxPanel(parent, id) {
	bsHauptanzeige = new wxBoxSizer(wxVERTICAL);
	sbmpKnopf = new LStaticBitmap(this, -1, wxBitmap(bild, wxBITMAP_TYPE_PNG));
	stBeschriftung = new LStaticText(this, -1, beschriftung);
	stBeschriftung->Connect(wxID_ANY, wxEVT_LEFT_DOWN, wxMouseEventHandler(VAdministration::klick));
	bsHauptanzeige->Add(sbmpKnopf, 0, wxALIGN_CENTER);
	bsHauptanzeige->Add(stBeschriftung, 0, wxALIGN_CENTER | wxTOP, 5);
	SetSizer(bsHauptanzeige);
}

void LKnopf::klick(wxMouseEvent &event) {
	printf("jo2\n");
	event.Skip();
}


// my test
VAdministration::VAdministration(wxWindow *parent, wxWindowID id) :
								wxDialog(parent, id, _("Administration"), wxDefaultPosition, wxDefaultSize) {
	wxBoxSizer *test = new wxBoxSizer(wxHORIZONTAL);
	test2 = new LKnopf(this, ADMIN_TEST, _("anzeigen.png"), _("Anzeigenbearbeitung"));
	test->Add(test2);
	SetSizer(test);
	
	test2->Connect(wxID_ANY, wxEVT_LEFT_DOWN, wxMouseEventHandler(VAdministration::klick));
}

Now only the panel execute VAdministration::klick. Thats realy correct (see the event tables). But I want that all components on the panel execute the event. Have I to deliver this function and if how can I do that?

It is the normal process.

If you look at the wxMouseEvent, it directly derives from wxEvent and not from wxCommandEvent so it is not passed to the parent window if not processed.

If you want this process, you must derive your own wxStatic* from the bases, use an event table to intercept mouse events and process them to the parent panel.

Or just simply set the eventhandler. (wxWindow::SetEventHandler)

Hi!

You can use Connect() for the label and bitmap, just like you tried. I do that for a thumbnail control with about the same setup and it works just fine.
Not that you should set the event sink to the panel when using Connect(). Instead of

Code: Select all

tBeschriftung->Connect(wxID_ANY, wxEVT_LEFT_DOWN, wxMouseEventHandler(LKnopf::klick));

try

Code: Select all

tBeschriftung->Connect(wxID_ANY, wxEVT_LEFT_DOWN, wxMouseEventHandler(LKnopf::klick),NULL,this);

to have LKnopf process the event. There is no need to create derived bitmaps and labels.

Hi!

Code: Select all

tBeschriftung->Connect(wxID_ANY, wxEVT_LEFT_DOWN, wxMouseEventHandler(LKnopf::klick),NULL,this);

Now it proccesses the LKnopf::klick, but I want to proccess VAdministration::klick without set it staticly:

Code: Select all

tBeschriftung->Connect(wxID_ANY, wxEVT_LEFT_DOWN, wxMouseEventHandler(VAdministration::klick),NULL,this);

because I want to use this button more than one time with different event. What I want is:

Code: Select all

LKnopf button1 = new LKnopf....
button1->Connect(..., wxMouseEvent(class::method1), ...);
LKnopf button2 = new LKnopf....
button2->Connect(..., wxMouseEvent(class::method2), ...);
LKnopf button3 = new LKnopf....
button3->Connect(..., wxMouseEvent(class::method3), ...);

I think I have to deliver the event-function to the LKnopf-Class, but I don't know how to do this. Something like that

Code: Select all

LKnopf::LKnopf(..., myDeliveredEvent, ...) {
   sbmpKnopf = new wxStaticBitmap(this...);
   sbmpKnopf->Connect(..., myDeliveredEvent, ...);
}

Then connect it to the correct event handler function and set the event sink to the VAdministration instance (in your case "parent").

[Morfio]

Ok, now I set the EventHandler:

stBeschriftung->SetEventHandler(this);
sbmpKnopf->SetEventHandler(this);

But now the static bitmap isn't repainted any more. How can I avoid this?

[Morfio]

Ahh, SetNextHandler works. Is this the correct way?

It's not the "wrong" way
PushEventHandler() might work, too.

[Morfio]

Ok, thank you all.
