Hi
It's not clear for me if it's possible to change dynamically the size of the graph axis.
The function gwinGraphDrawAxis seems to do that but i do not understand how should work
Can anyone provide an example?
-
It works! Thank you very much

I'd like to switch between images (normal button and pressed button) when a specific button is pressed
I want to use my set of routine for manage the events, so i need to change the image of the pressed and released button by my code
A single image (normal button) is size 50x49, so i've merged the two images in a single file size 50 x 98
Is there a way to switch between the two images in a similar way that you do with your GINPUT/GEVENT mode ? (i mean programmatically)
It's clear to me the way to switch between two different images (size 50x49), but i was wondering if there was the possibility to use a single image file

Is it possible to change the image of a Push Button programmatically without use GEVENT (and GINPUT) ?
Thanks

It's hard to explain but i'll try..
In my project i perfrom many gwinSetText that writes on different labels updating values, for example a time clock
The refresh seems to be good but every 10-15 seconds i get a noisy "black refresh" on the widget
In attachment my ugfx configuration. Any idea why this happen?
The same thing happen if i put an image on another image and i perform gwinSetVisible action in way to switch betweeen images (like if it's a button)
Some times i get a black area on the image.
My project is a baremetal so there are not other threads and readrawing operations should be immediate.
My MCU is a K64F Cortex M4 at 120Mhz... i don't think i should have these problems.. what do you think it could be?
Thank you

Hi,
i have a question about the navigation throught menus
I have for example three menus : A() , B() , C()
Whan i call for example the function A() it performs :
- a full clear screen (my primitive for my screen)
- set invisible every widget on menu B (gwinSetVisible)
- set invisible every widget on menu C (gwinSetVisible)
- destroy every widget on menu A (gwinDestroy)
- create every widget on menu A (gwinLabelCreate)
- set visible every widget on menu A(gwinSetVisible)
- redraw every widget on menu A (gwinRedraw)
Whan i call the function B() it performs :
- a full clear screen (my primitive for my screen)
- set invisible every widget on menu C (gwinSetVisible)
- set invisible every widget on menu A (gwinSetVisible)
- destroy every widget on menu B (gwinDestroy)
- create every widget on menu B (gwinLabelCreate)
- set visible every widget on menu B(gwinSetVisible)
- redraw every widget on menu B (gwinRedraw)
etc...
It works, but it's very slow.
I'm sure this is not the best method. I know for example that containers can perform destroy actions on all his child.
Now i ask what are the right actions to perform a simple navigation throught menus and if exists examples about thatThank you
-
Thank you very much!
This example is very clear
Do you have other routines example for make round buttons or something similar?

Hi folks!
Does someone wants to share their widgets rendering functions?
Graphically I'm not very good so if anyone has some nice graphical effects (for example on the buttons) to share it would be really appreciated
I would be very interested to know how you can achieve gradient effects
Thank you!
-
Ok, thank you
I also ask if it is possible to customize the widgets items for example the lighting color of a key pressed?

Hi
Is it possible to change the layout of the widget "Keyboard" on the display to a numeric keypad?
Thanks

Hi
I am having trouble viewing more than 2 images in the same screen.
I've imported 3 bmp into uGFX studio and generated the header file.
The code for load a single BMP is this:
GHandle ghImagebox3; wi.g.show = TRUE; wi.g.x = 400; wi.g.y = 150; wi.g.width = 67; wi.g.height = 67; ghImagebox3 = gwinImageCreate(0, &wi.g); gwinImageOpenMemory(ghImagebox3, ico3);It works perfecty until i load 2 BMP
Whan i try to open the third i cannot see it on the display
I'm absolutely sure that x and y are in a valid area of the screen and there are not others widget on this area.
Every ghImageBox element seems to be initialized correctly so i can understand why the image is not visible
Suggest?

Good morning
I'd like to make the following thing:
- Draw a graph (it's ok)
- Show an image (or a box containing a fixed value or text)
- The image should blink on the graph until another graph startFor example i want to see the image on "example1.jpg" , after few seconds "example2.jpg", after few seconds "example1.jpg" , etc..
Obviously the problem is the redrawing of the graph
I think that the best way is to store the graph points then draw the image and redraw the missing points until the box is blinking
I'd like to have suggests if there are better ways to do what i want or if i'm taking a wrong way
Thank you very much and congratulations for the support that you bring to every userP.S.
i can't use pixmap module because i can't include it with makefile
others modules works properly
-
About a.
I've enabled PIXELMAP in the configuration and i get some compilation errors
This topic has already discussed here:
I'm using SD1963 driver with KDS 3.2.0 on a K64F by freescale (nxp)
-
Thank you for the suggests Joel
a. I will try
b. I've tryed but is not working.. the TTF file is ok and the characters have all the same width, but when i export them and check the size (gdispGetStringWidth) i get different width values
for example:
"0" --> 43 pixels
"1" --> 44 pixels
"2" --> 43 pixels
etc..
in your opinion on what you can depend this additional pixels?
c. ok it works! i've made a mistake in the settings property of a label
-
Hi
I've seen a lot of project examples showing numberic values changes in real time
I'm trying to do the same with a label widget but i have some issues:
a. Using gwinSetText i get a refresh of the whole string so i get an annoying effect because all the area is turned black and redrawed character by character.
b. Every digit can have a different width from each other so if i refresh them is it possible to see each character move left or right. Although this effect is annoying.
c. The label widget doesnt have a left alignment. For example if i want to put a counter in the top-right of the corner it should see the number increasing its digits from the right to the left.
So i ve made an array of label. Every label contain a single digit or a "." , so the width is fixed to the maximum width of a digit or the width of a "." and this solve the b. and also a. because using array i can refresh only digits that are changed
I'm working on c. because it is necessary to reverse the original string and do some stuff
I wonder if anyone has already had to deal with these problems and how he dealt
I'd like to know if there are ways more 'effective and maybe already made that resolve the problems I have described

UPDATE
I've made a preset with a font Isonorm Bold (IsonormBold.ttf)
http://oi64.tinypic.com/5l2clu.jpg
I've made another preset with a font Isonorm Regular (Isonorm-regular.ttf)
http://oi65.tinypic.com/2yud940.jpg
In uGFX Studio when i set the regular font preset to a label i get this:
http://oi65.tinypic.com/20573u1.jpg
If i apply the bold preset to another label i continue to see the regular version:
http://oi67.tinypic.com/msjhvp.jpg
It's quite strange
I get the same thing on the display
-
Absolutely not a priority for me
I think the problem is in the wrong export of the TTF modified (regular size ~ 123k , modified size ~ 59k )
If I can fix i'll let you know
-
In attachment the font i've used
Isonorm-regular.ttf is the starting true type font and it works but i have only the regular version, so i've tryed to edit the numbers and make them in bold using FontForge (changing the width)
http://oi65.tinypic.com/2iuu68y.jpg
The result is Isonorm_modified.ttf
When i try to build the array to convert the TTF to .C file i get a bad format error message
Probably i make a mistake or maybe the tool i've used is wrong for do this
-
Yes, I realized later how had to work
I think that makefile also should work because KDS use Eclipse that support ".mk" files but i had compilation errors so i changed way and this workaround works for me
You can add "K64F" to your supported microcontrollers list
-
Hello
I've searched on the forum about the topic but nothing i've found
My question is: how can i import a TTF bold?
I've seen in the examples that Dejavu Font already start in bold version. What tool have you used? I've tryed FontForge but when i try to convert the TTF to .C table i get a wrong format message
-
I think some references in "gdisp/fonts" that point to "gfx.h"
-
It works!
It was quite complicated to reconstruct the right hierarchy of the modules but in the end it works.
Some useful tips:
- makefile don't work for me in KDS so i used the inclusion of "gfx_mk.c"
- many path into the g-directory have a wrong path ("../.." missing) so... enjoy
& good luck to redefine them!
- try to change values from the top to the bottom of the "gfxconf.h" and see if compile errors decrease
- check to put "TRUE" the show of the widget ghContainerPage0 (into "gui.c") because was set "FALSE" by default from the uGFX Studio
- "gl" is a variable set by the environment so it is necessary to change the name into the "gui.c" (GListener)

Tested on K64F with KDS 3.2.0 on ARM Cortex M4
Thank you very much
Graph axis size
in Support
Posted · Edited by ForTest
Ok, so this is the default graph style i use How should i change it for have for example a x/y axis line size of 3 pixel?// A graph styling static GGraphStyle GraphStyle1 = { { GGRAPH_POINT_DOT, 2, Red }, // Point { GGRAPH_LINE_SOLID, 1, Red }, // Line { GGRAPH_LINE_SOLID, 25, Black }, // X axis { GGRAPH_LINE_SOLID, 25, Black }, // Y axis { GGRAPH_LINE_DOT, 5, Gray, 50 }, // X grid { GGRAPH_LINE_DOT, 5, Gray, 50 }, // Y grid GWIN_GRAPH_STYLE_POSITIVE_AXIS_ARROWS // Flags };
