Probleme avec Form1_DragEnter

Voila j'ai crée une petite appli ou je crée en Graphics une petite bar de position pour pouvoir naviguer dans une video. En gros le meme principe qu'un lecteur video.
Pour l'instant, l'utilisateur peux cliquer sur cette barre pour l'amener ou il le souhaite dans la video. Mais j'aimerais maitenant qu'il puisse faire du drag sur cette bar. J'ai donc crée cette fonction :

déclaration :

Code:

---

1 2	this->DragEnter += gcnew System::Windows::Forms::DragEventHandler(this, &Form1::Form1_DragEnter);

---

événement :

Code:

---

1 2 3 4 5 6 7

private: System::Void Form1_DragEnter(System::Object ^ sender,System::Windows::Forms::DragEventArgs ^ e) {   //bla bla bla   }

---

Mon souci est qu'apparement Form1_DragEnter n'est pas membre de MaForm::Form1. J'ai regardé sur le net et tout le monde le déclare comme ca. Alors je ne sais pas pourquoi chez moi ca ne marche pas...

PS: Pour précision, pour mon appli, il vaut utiliser quel type de Drag, DragEnter, DragDrop ? En fait j'ai juste besoin de connaitre en temps réel les coordonnées de la souris ;)


Merci de votre aide !

Voyons voir ce que les gens de C++/CLI en pensent ;)

tu as utilisé l'assistant pour générer la fonction ?

Non je l'ai généré moi meme.

Aurais je oublié quelquechose, parceque pour les autres événements que j'ai crée, ca marchait tres bien !

on peut ptete voir tout le code et l'erreur du compilo ?

question con, tu as bien mis dans la méthode dans la classe ? dans le meme .h ? dans un .cpp ? (si oui, n'as-tu pas oublié l'opérateur de résolution de portée ? et le namespace ?)

Bon voila mon code :

Code:

Et bizarrement, je viens d'essayer de compiler pour récupérer l'erreur, mais en fait plus d'erreur ! :yaisse2:

Ce pendant rien ne s'inscrit dans ma picturebox, je m'y connais tres peu en drag and drop, je sais pas si DragEnter est la bonne solution...

Voila merci de votre aide !

tu peux poster un exemple minimal qui reproduit ton problème ? parce que j'avoue ne pas avoir trop compris ce que tu voulais faire, et qui tu voulais draguer ?

En fait maintenant je n'ai plus d'erreur lors de la compilation tout marche nickel !

Pour tester si mon événement marche bien des que je l'execute, j'ai fait ce petit test :

Code:

---

1 2 3 4 5 6 7

private: System::Void Form1_DragEnter(System::Object ^ sender,System::Windows::Forms::DragEventArgs ^ e) {   textBox1->Text="ca marche";   }

---

Mais voila, quand je clique sur ma souris et que je me déplace, rien se passe. Rien d'afficher dans la textbox, et de toute facon quand je met un point d'arret dans ma fonction, je ne passe pas dedans.

Bref, ce que je voudrais faire ca serait de récupérer les coordonnées de ma souris qui se déplace en temps réel. En fait j'ai crée moi meme une petite scrollbar, et j'aimerai pouvoir y incruster le drag and drop.

Mais au final je ne sais pas trop quel événement utilisé, peut etre que je pars totalement dans la mauvaise direction avec mon dragenter. Je suis ouvert à toute critique ! :D

Merci Nico !

ben, moi j'aurai plutot travaillé sur l'événement MouseDown
avec un boolean qui passe à true quand c'est cliqué, et qui passe à false quand le bouton est relaché.
Dans l'evenement mouseMove, tant qu'il est appuyé, tu fais ton déplacement

tiens, il y a un truc dans la faq C++/CLI qui se rapproche de ce que tu veux faire http://dotnet.developpez.com/faq/cpp...ms#MoveControl

Ecoute tout ce que je peux te dire Nico c'est merci !:king:

J'utilisais deja l'évenement MouseDown, et quand j'ai commencé à regarder pour le drag and drop je me suis jeté sans réflechir sur l'évenement du meme nom.
Alors que l'événement MouseMouve était bien plus approprié à mon cas !

Maintenant ca marche nickel, ton lien m'a bien aidé ;)
