ループが私の機能ボタンを認識しないwhileボタン

Question

ボタンが押されたときに実行されるスクリプトがあり、whileループを開始します。私の停止ボタンが押されると、それはループ条件を真実にさせてループを停止させるはずです。私の停止ボタンはテスト中にループを止めていないようです。私がpushDisconnectボタンで割り当てた値がwhileループに更新されていないように見えますが、なぜこれが起こっているのかわかりません。

Answer 1

がguidata(hObject, handles)ラインを殺し、そしてhandles=guidata(hObject)でそれを置き換えますGUIの状態をポーリングする必要があります。 handles.stopNowが実際にそれが解決しない場合は、追加の問題は、他のコールバックがあるまで、MATLABは1つのボタンのコールバックから処理コマンドを待機するかもしれ0

にリセットされることを保証するために、ループの前にguidata(hObject, handles) -lineを置きます実行を完了しました。

2つの方法を試すことができます：一時停止の前にdrawnowコマンドを追加してください。これにより、GUIが強制的に更新され、すべての対話が処理されます。また、pushConnectのプッシュボタンコールバックが割り込み可能であることを確認してください。
