Forms on Windows 7 and Vista have thicker borders than those of XP. As a result, some content that spans the entire height or width of a form will be cut off. Is there a simple way to fix this, or do all the forms of my application need to be resized to accommodate for this?
Update: It appears to be the fault of the form size and not the borders that are causing the problem. See the following images for an example. Notice how the controls have the correct location at the top-right corners, but they reach the each of the form in Windows 7 while a border is retained in XP. The same code is used to resize and position the controls.
Here's what a form looks like in XP:

You should fix the size of the form programatically, to make sure the client size is big enough to fit everything. You can easily calculate the difference between the current size and client size of the form, and increase/decrease by the right amount.
You probably want to perform this inside Form_Load.
In VB6, the client size and width are referred to as ScaleWidth and ScaleHeight for forms. Setting these values just messes up the scaling, rather than resizing the form, so you instead have to do calculations so you can set the normal Width and Height properties.
BorderSize = Me.Width - Me.ScaleWidth
Me.Width = BorderSize + CorrectScaleWidth
//Same for height!

Can someone help me in understanding how to calculate the Height and Width of a Powershell Forms. For Example I Created a blank Powershell form of Height 500 and Width 700 and now If want to place a Text box a little below from the top of the form what will be the height and width that I need to enter? and If I want to place a Button at middle of the Form? what will be the height and width that I need to enter? I am struggling with this calculation.
You should get the screen size and use the ratio to set position. The ratio is useful for different screen size.
I have an UI element that has a Text and an Image as its children. It has a HorizontalLayoutGroup component that enables Control Child Size and Child Force Expand.
I want the Image has a fixed size, and Text has strechable size controlled by the HorizontalLayoutGroup. So when the Image is set to inactive, the Text fills the whole space and when the Image is active, the Text shrinks a little bit in order to give space to the Image. Right now this part works good.
My second goal is to align them to both ends: the Text in the left and the Image on the right with space in between. But changing Child Alignment can't achieve this.
I tried the following solution:
Add LayoutElement both to Image and Text. On Text, enable Flexible Width and set a a value, on Image, enable Min Width and set to a value. Manually adjust the two values until it seems right.
This solution seems to work, but I don't know why. Is anyone familiar with this?What's the recommended way to do it? Thanks!
I worked it out. On the LayoutElement, treat Preferred Width or Preferred Height as Max Width or Max Height. Enable them, set the value the same with min value. One the other objects that you want to stretch, enable Flexible values. Then all worked as we want.
I'm using GTK3+ (3.22) on Ubuntu server 18 (beta2) / x11 / openbox. Language is C. I'm porting an embedded application from GTK2 which did not seem to do dynamic resizing of label widgets when the text content reached a certain limit.
On GTK3 the label (and button) widgets now seem to resize when the text content is close to the maximum size that can be displayed.
In the case of a button widget placed into a FIXED container on a window. I have tried the following...
The gtk_widget_set_size_request seems only to set a default or minimum, not a max:
gtk_widget_set_size_request( GTK_WIDGET( GuiBottomFarLeftButton ) , GuiBottomButtonWidth , GuiBottomButtonHeight );
I have tried gtk_widget_size_allocate but that doesn't seem to limit the maximum size.
GtkAllocation gtkallocTestSize = { GuiBottomButtonFarLeftX , GuiBottomButtonY , GuiBottomButtonWidth , GuiBottomButtonHeight};
gtk_widget_size_allocate( GTK_WIDGET( GuiBottomFarLeftButton ) , >kallocTestSize );
There does not appear to be a gtk_widget_... function that limits the maximum size or sizing behavior that I can find. So far I have not found a way to limit the maximum size of a specific widget. I would settle for a way to limit the maximum width as the vertical size of the controls seems to behave as it did under GTK2 in the application I'm working on. In most cases the resizing is only effecting the layout by 10 to 20 pixels but this creates a really bad user experience.
Is there a way to disable the resizing on a widget or limit it's maximum size? Or some other work around that actually functions on latest GTK3+ (3.22)?
UX is a hard balance of optimisation. In general you should not assume that the gtk2 behaviour is what you want to replicate. The body of knowledge re: UX has increased since then and changes are in general positive. You will either be clipping text, decreasing font sizes or oversizing widgets. You can't have it all.
Scrolled windows help in many cases but obviously not for buttons and labels. In this case it is best to keep text short and use tooltips for anything that needs a more lengthy explanation.
Is there a way to change the height of a text field on the whole figure without changing the x and y position?
To change we must use the position, which requires to change the coordinates. I would like to change only the height, without changing x and y.
Just store the current x and y, and use those in your set call like so:
old_pos = get(text_field_handle,'Position');
set(text_field_handle,'Position',[old_pos(1:2),new_width,new_height]);
Well, you can change the FontSize property, this won't change the coordinates, but will increase width as well as height. See Text Properties in the doc for more details.
I am assuming you are working with uicontrol('style','text').
From the uicontrol properties you have:
Position
position rectangle
*Size and location of uicontrol*. The rectangle defined by this property
specifies the size and location of the control within the parent figure
window, uipanel, or uibuttongroup. Specify Position as:
[left bottom width height]
where left and bottom define the distance from the lower-left corner of the
container to the lower-left corner of the rectangle. width and height are the
dimensions of the uicontrol rectangle.
You can then just change the width and height keeping the original left and bottom.
One can set the Margin property of a text object to increase the height of the object without changing the fontsize, but this influences both the height and the width of the text object. I am not sure what it means to make the height smaller than what Matlab thinks is the text height, so I will assume you are interested in increasing the size.
Increasing the height of the text object is relatively easy if you are willing to use the LaTeX interpreter. You just need to add an "empty" box of whatever height you want:
text(0.5, 0.25, 'Hello World\parbox{\textwidth}{\vspace{1in}}', 'Interpreter', 'LaTeX', 'BackgroundColor',[1, 0, 0]);
This won't increase the height by exactly 1 inch, instead it will be more like 1 inch minus a baseline skip. Determining the actual height increase in displayed units adds even more problems. You might be able to change the height with unicode characters, and hence skip the LaTeX interpreter, but I have no idea how.
I am trying to use a UIImage with stretchableImageWithLeftCapWidth to set the image in my UIImageView but am encountering a strange scaling bug. Basically picture my image as an oval that is 31 pixels wide. The left and right 15 pixels are the caps and the middle single pixel is the scaled portion.
This works fine if I set the left cap to 15. However, if I set it to, say, 4. I would expect to get a 'center' portion that is a bit curved as it spans the center while the ends are a little pinched.
What I get is the left cap seemingly correct, followed by a long middle portion that is as if I scaled the single pixel at pixel 5, then a portion at the right of the image where it expands and closes over a width about twice the width of the original image. The resulting image is like a thermometer bulb.
Has anyone seen odd behavior like this and might know what's going on?
Your observation is correct, Joey. StretchableImageWithLeftCapWidth does NOT expand the whole center of the image as you would expect. It only expands the pixel column just right of the left cap and the pixel row just below the top cap!
Use UIView's contentStretch property instead, and your problem will be solved. Another advantage to this is that contentStretch can also shrink a graphic properly, whereas stretchableImageWithLeftCapWidth only works when making the graphic larger.
Not sure if I got you right, but LeftCapWidth etc is made for rounded corners, with everything in the rectangle within the rounding radius is stretched to fit the space between the 'caps' on the destination button or such.
So if your oval is taller or wider than 4 x 2 = 8, whatever is in the middle rectangle will be stretched. And yours is, so it would at least look at bit ugly! But if it's not even symmetrical, something has affected the stretch. Maybe something to do with origin or frame, or when it's set, or maybe it's set twice, or you have two different stretched images on top of each other giving the thermometer look.
I once created two identical buttons in the same place, using the same retained object - of course throwing away the previous button. Then I wondered why the heck the button didn't disappear when I set alpha to 0... But it did, it's just that there was a 'dead' identical button beneath it :)
