<span class="post-date">Cts 26 Şubat 2022</span>
<h1>Komut Dosyasıyla Yazılmış Nesneler</h1>
<h2>Takdim</h2>
<p>Açıklamalar, ağlar ve parça nesneleri gibi standart nesne türlerinin yanı sıra, FreeCAD ayrıca <a href="https://wiki.freecadweb.org/App_FeaturePython">Python Özellikleri</a> adı verilen %100 python komut dosyasıyla oluşturulmuş parametrik nesneler oluşturmak için harika bir olanak sunar. Bu nesneler, tam
olarak diğer herhangi bir FreeCAD nesnesi gibi davranacak ve dosya kaydetme/yükleme sırasında otomatik olarak kaydedilecek ve geri yüklenecektir.</p>
<p>Anlaşılması, bilinmesi gereken bir husus var, o da şudur: FreeCAD dosyaları hiçbir zaman gömülü kod taşımaz, bu güvenlik nedenleriyledir.
Parametrik nesneler oluşturmak için yazdığınız Python kodu, hiçbir zaman bir dosyanın içine kaydedilmez. Bu, başka bir makinede (bilgisayarda) böyle bir nesne içeren bir dosyayı açarsanız, bu python kodu o makinede (bilgisayarda) mevcut değilse, nesnenin tamamen yeniden oluşturulmayacağı anlamına gelir. Bu tür nesneleri başkalarına
dağıtırsanız (gönderirseniz), Python komut dosyanızı da örneğin bir <a href="https://wiki.freecadweb.org/Macros">Makro</a> olarak dağıtmanız, göndermeniz gerekir.</p>
<p><strong>Not:</strong> Python kodunu bir <code>App::PropertyPythonObject</code> ile <code>json</code>serileştirmeyi kullanarak bir FreeCAD dosyası içinde paketlemek (yerleştirmek) mümkündür, ancak bu kod hiçbir zaman doğrudan çalıştırılamaz ve bu nedenle buradaki amacımız için çok kullanışlı değildir.</p>
<p><a href="https://wiki.freecadweb.org/App_FeaturePython">Python Özellikleri</a>, tüm FreeCAD özellikleriyle aynı kuralı izler: <code>App</code>ve <code>GUI</code>bölümlerine ayrılırlar. <code>App</code> bölümü, Belge Nesnesi, nesnemizin geometrisini tanımlarken, <code>GUI</code> bölümü, Görünüm Sağlayıcı Nesnesi, nesnenin ekranda nasıl çizileceğini tanımlar. Görünüm Sağlayıcı Nesnesi, diğer FreeCAD özellikleri gibi, yalnızca FreeCAD'i kendi GUI'sinde çalıştırdığınızda kullanılabilir. Nesnenizi oluşturmak için kullanılabilecek birkaç özellik ve yöntem vardır. Özellikler, FreeCAD'in sunduğu önceden tanımlanmış özellik türlerinden herhangi biri olmalıdır ve kullanıcı tarafından düzenlenebilmeleri için özellik görünümü penceresinde görünecektir. Bu şekilde, <code>FeaturePython</code> nesneleri gerçekten ve tamamen parametriktir. <code>Object</code> ve <code>ViewObject</code> için özellikleri ayrı ayrı tanımlayabilirsiniz.</p>

<h2>Dikkat Edilmesi Gerekenler</h2>
<p>Nesneniz oluşturulur oluşturulmaz yeniden hesaplanması gerekiyorsa, otomatik olarak çağrılmadığı için bunu <code>__init__</code> işlevinde manuel olarak yapmanız gerekir. <code>Box</code>sınıfının <code>onChanged</code> yöntemi, <code>execute</code> (çalıştır) fonksiyonuyla aynı etkiye sahip olduğu için bu örnek buna gerek duymaz, ancak aşağıdaki örnekler, 3B görünümde herhangi bir şey görüntülenmeden önce yeniden hesaplanma mantığına dayanır. Örneklerde
bu, <code>ActiveDocument.recompute()</code> ile manuel olarak yapılır, ancak daha karmaşık senaryolarda, tüm belgenin veya <code>FeaturePython</code> nesnesinin nerede yeniden hesaplanacağına karar vermeniz gerekir.</p>
<p>Bu örnek, <strong>rapor görünümü penceresi</strong>nde bir dizi istisna yığını izi üretir. Bunun nedeni, <code>__init__</code> içine her özellik eklendiğinde <code>Box</code> sınıfının <code>onChanged</code> yönteminin çağrılmasıdır. İlki eklendiğinde, <strong>Genişlik</strong> ve <strong>Yükseklik</strong> özellikleri henüz mevcut değildir ve bu nedenle bunlara erişme girişimi başarısız olur.</p>
<p><code>__getstate__</code> ve <code>__setstate__</code> için bir açıklama <a href="https://forum.freecadweb.org/viewtopic.php?f=18&t=44009&start=10#p377892">obj.Proxy.Type is a dict, not a string</a> forum başlığında bulunmaktadır.</p>

<h2>Kullanılabilir Özellikler</h2>
<p>Özellikler, <code>FeaturePython</code> nesnelerinin gerçek yapı taşlarıdır. Bunlar aracılığıyla, kullanıcı etkileşimde bulunabilecek ve nesnenizi değiştirebilecektir. Belgenizde yeni bir <code>FeaturePython</code> nesnesi oluşturduktan sonra;</p>
<p>(<code>obj=FreeCAD.ActiveDocument.addObject("App::FeaturePython","Box")</code>), aşağıdaki kodu yazarak, kullanılabilir özelliklerin bir listesini elde edebilirsiniz:</p>

<p>Özel nesnelerinize özellikler eklerken şunlara dikkat edin:</p>
<ul>
<li>
<p>Özellikler açıklamalarında <code><</code> veya <code>></code> karakterlerini kullanmayın (bu, <strong>.fcstd</strong> dosyasındaki <strong>xml</strong> parçalarını bozar)</p>
</li>
<li>
<p>Özellikler bir <strong>.fcstd</strong> dosyasında alfabetik olarak saklanır. Eğer özelliklerinizde bir şekil varsa, ismi alfabetik olarak "Şekil"den sonra gelen herhangi bir özellik şekilden SONRA yüklenecektir ve bu da garip davranışlara neden olabilir.</p>
</li>
</ul>
<p>Özellik özniteliklerinin tam listesi <a href="https://github.com/FreeCAD/FreeCAD/blob/master/src/App/PropertyStandard.h">PropertyStandard C++ başlık dosyasında</a> görülebilir. Örneğin, kullanıcının yalnız sınırlı bir değer aralığı girmesine izin vermek istiyorsanız (örneğin <code>PropertyIntegerConstraint</code> kullanarak), Python'da yalnız özellik değerini değil, aynı zamanda alt ve üst sınırı ve adım boyutunu da içeren bir tanımlama grubu
atayacaksınız, aşağıda olduğu gibi:</p>
<div class="highlight"><pre><span></span><code><span class="n">prop</span> <span class="o">=</span> <span class="p">(</span><span class="n">value</span><span class="p">,</span> <span class="n">lower</span><span class="p">,</span> <span class="n">upper</span><span class="p">,</span> <span class="n">stepsize</span><span class="p">)</span>
</code></pre></div>
<h2>Özellik Türü</h2>
<p>Varsayılan olarak özellikler güncellenebilir. Örneğin bir yöntemin, sonucunu göstermek istemesi durumunda, özellikleri salt okunur yapmak mümkündür. Ayrıca özelliği gizlemek de mümkündür. Özellik türü aşağıdakiler kullanılarak ayarlanabilir:</p>
<div class="highlight"><pre><span></span><code><span class="n">obj</span><span class="o">.</span><span class="n">setEditorMode</span><span class="p">(</span><span class="s2">"MyPropertyName"</span><span class="p">,</span> <span class="n">mode</span><span class="p">)</span>
</code></pre></div>
<p>mod, şu şekilde ayarlanabilen kısa bir tamsayıdır (int):</p>
<div class="highlight"><pre><span></span><code><span class="mi">0</span> <span class="o">--</span> <span class="n">varsayılan</span> <span class="n">mod</span><span class="p">,</span> <span class="n">okuma</span> <span class="n">ve</span> <span class="n">yazma</span> <span class="p">(</span><span class="n">default</span> <span class="n">mode</span><span class="p">,</span> <span class="n">read</span> <span class="ow">and</span> <span class="n">write</span><span class="p">)</span>
<span class="mi">1</span> <span class="o">--</span> <span class="n">Salt</span> <span class="n">okunur</span> <span class="p">(</span><span class="n">read</span><span class="o">-</span><span class="n">only</span><span class="p">)</span>
<span class="mi">2</span> <span class="o">--</span> <span class="n">gizli</span> <span class="p">(</span><span class="n">hidden</span><span class="p">)</span>
</code></pre></div>
<p>EditörModları, FreeCAD dosyasının yeniden yüklenmesine ayarlanmamıştır. Bu, <code>__setstate__</code> fonksiyonu tarafından yapılabilir. <a href="http://forum.freecadweb.org/viewtopic.php?f=18&t=13460&start=10#p108072">Eigenmode frequency always 0? - Page 2 - FreeCAD Forum</a> adresine bakın. <code>setEditorMode</code> kullanılarak, özellikler yalnızca <strong>PropertyEditor</strong>'de okunur. Hala python'dan değiştirilebilirler. Bunları gerçekten okumalarını sağlamak için, ayarın doğrudan <code>addProperty</code> fonksiyonunun içine iletilmesi gerekir. Örnek için <a href="http://forum.freecadweb.org/viewtopic.php?f=18&t=13460&start=20#p109709">Eigenmode frequency always 0? - Page 3 - FreeCAD Forum</a> adresine bakın.</p>
<p><code>AddProperty</code> fonksiyonundaki doğrudan ayarı kullanarak, daha fazla olanağınız da olur. Özellikle, bir özelliği çıktı özelliği olarak işaretlemek ilginçtir. Bu şekilde FreeCAD, özelliği değiştirirken dokunulduğunda işaretlemeyecektir (böylece yeniden hesaplamaya gerek yoktur).</p>
<p>Çıktı özelliği örneği (ayrıca bkz. <a href="https://forum.freecadweb.org/viewtopic.php?t=24928">[Solved] Skip excution for some properties - FreeCAD Forum</a>):</p>
