[Mono-dev] TableLayout problem in winforms between Win32 (.NET) and mono

[Paul]

Hi,

I've built an application which runs happily under Win32 and mono. The
design work was done under VS C# 2008, was compiled on there and tested
on both my Linux (fedora) boxes and an XP box.

On XP, everything works fine. Under Linux, the text boxes are not
correctly sized.

The setup code from the Win designer for the table is this

            this.table.ColumnCount = 6;
            this.table.ColumnStyles.Add(new
System.Windows.Forms.ColumnStyle(System.Windows.Forms.SizeType.Absolute,
60F));
            this.table.ColumnStyles.Add(new
System.Windows.Forms.ColumnStyle(System.Windows.Forms.SizeType.Percent,
25F));
            this.table.ColumnStyles.Add(new
System.Windows.Forms.ColumnStyle(System.Windows.Forms.SizeType.Percent,
25F));
            this.table.ColumnStyles.Add(new
System.Windows.Forms.ColumnStyle(System.Windows.Forms.SizeType.Percent,
25F));
            this.table.ColumnStyles.Add(new
System.Windows.Forms.ColumnStyle(System.Windows.Forms.SizeType.Percent,
25F));
            this.table.ColumnStyles.Add(new
System.Windows.Forms.ColumnStyle(System.Windows.Forms.SizeType.Absolute,
40F));
            this.table.Controls.Add(this.checkBox4, 5, 4);
            this.table.Controls.Add(this.checkBox3, 5, 3);
            this.table.Controls.Add(this.checkBox2, 5, 2);
            this.table.Controls.Add(this.diff4, 4, 4);
            this.table.Controls.Add(this.ass4, 3, 4);
            this.table.Controls.Add(this.teach4, 2, 4);
            this.table.Controls.Add(this.active4, 1, 4);
            this.table.Controls.Add(this.diff3, 4, 3);
            this.table.Controls.Add(this.ass3, 3, 3);
            this.table.Controls.Add(this.teach3, 2, 3);
            this.table.Controls.Add(this.active3, 1, 3);
            this.table.Controls.Add(this.diff2, 4, 2);
            this.table.Controls.Add(this.ass2, 3, 2);
            this.table.Controls.Add(this.teach2, 2, 2);
            this.table.Controls.Add(this.active2, 1, 2);
            this.table.Controls.Add(this.diff1, 4, 1);
            this.table.Controls.Add(this.ass1, 3, 1);
            this.table.Controls.Add(this.teach1, 2, 1);
            this.table.Controls.Add(this.label6, 5, 0);
            this.table.Controls.Add(this.label5, 4, 0);
            this.table.Controls.Add(this.label4, 3, 0);
            this.table.Controls.Add(this.label3, 2, 0);
            this.table.Controls.Add(this.label2, 1, 0);
            this.table.Controls.Add(this.label1, 0, 0);
            this.table.Controls.Add(this.numericUpDown1, 0, 1);
            this.table.Controls.Add(this.numericUpDown2, 0, 2);
            this.table.Controls.Add(this.numericUpDown3, 0, 3);
            this.table.Controls.Add(this.numericUpDown4, 0, 4);
            this.table.Controls.Add(this.active1, 1, 1);
            this.table.Controls.Add(this.checkBox1, 5, 1);
            this.table.Location = new System.Drawing.Point(6, 6);
            this.table.Name = "table";
            this.table.RowCount = 5;
            this.table.RowStyles.Add(new
System.Windows.Forms.RowStyle(System.Windows.Forms.SizeType.Absolute,
20F));
            this.table.RowStyles.Add(new
System.Windows.Forms.RowStyle(System.Windows.Forms.SizeType.Percent,
25F));
            this.table.RowStyles.Add(new
System.Windows.Forms.RowStyle(System.Windows.Forms.SizeType.Percent,
25F));
            this.table.RowStyles.Add(new
System.Windows.Forms.RowStyle(System.Windows.Forms.SizeType.Percent,
25F));
            this.table.RowStyles.Add(new
System.Windows.Forms.RowStyle(System.Windows.Forms.SizeType.Percent,
25F));
            this.table.Size = new System.Drawing.Size(605, 202);
            this.table.TabIndex = 1;

So, as you can see, the table width is 605, two columns make 100 leaving
505, there is a gap between each cell so the largest textbox there can
be is 495 in length).

The window itself has a radio button which that does the following

1. Makes all except active1-4 visible=false
2. Sets the column span to 4
3. Makes the active1-4 textboxes 495,39

The other radio button does the reverse.

The problem is that under Linux there are gaps where they shouldn't be.

I've uploaded two screenshots showing what is happening

Is this a known bug or do I need to put it into BZ?

TTFN
