Subject: [Lazarus] MDI implementation<div><br><br>Hi there.<br><br>I'm trying to write a MDI application in Lazarus (Win32/Vista, Lazarus 0.9.31).<br><br>I created the main form and set its FormStyle property to fsMDIForm. Then I created the child form and set its FormsStyle to fsMDIChild.<br>
<br>I also created a menu where I can start a new form. I moved the child form the non-automatic-created form list. And used the following code to create it:<br><br>-----------------<br>procedure TfrmMain.mnuEntrarDadosClick(Sender: TObject);<br>
var frmChild: TfrmRelatVend;<br>begin<br> frmChild := TfrmRelatVend.Create(self);<br> frmChild.Show;<br>end; <br>-----------------<br><br>I also wrote a formClose handler for the child so it gets freed when I close it.<br>
-----------------<br>procedure TfrmRelatVend.FormClose(Sender: TObject;<br> var CloseAction: TCloseAction);<br>begin<br> CloseAction := caFree;<br>end; <br>-----------------<br><br>>Altough the form gets created and shows up, it does not have a MDI behavior, eg, it does not "stay" in the limits of its parent form and it gets maximized on top of its parent form.<br>
<br>>What am I doing wrong?<br><br>>thank you<br><br clear="all"></div>I cannot tell you exactly what you're doing wrong, but I can do the next best thing.<div><br></div><div>I have a Simple_Ed (simple text editor) which supports unlimited MDI child text windows working.</div>
